Haidong (Chinese: 海东市; pinyin: Hǎidōng shì) is a prefecture-level city of Qinghai province in Western China. Its name literally means "east of the (Qinghai) Lake." On 8 February 2013 Haidong was upgraded from a prefecture (海东地区) into a prefecture-level city.[3] Haidong is the third most populous administrative division in Qinghai after Xining and Golmud.

Haidong was historically populated by the Qiang people, although the area has been inhabited as early as 6000 years ago. In 121 BC the area was captured by Huo Qubing, defeating the Xiongnu. In 399 AD the Xianbei founded the state of Nanliang, with its capital in Ledu District.[4]

Geography

[edit]

Haidong is the easternmost division of Qinghai province. It is bounded by Xining, the provincial capital, to the West, the Datong River Valley to the north, Gansu to the east, and the Yellow River to the south. Mountain ranges tower above the district of which the main valley is that of the Huang Shui (Tib. Tsong Chu), a major tributary of the Yellow River. This valley stretches from west to east and makes up - together with the area around Xining, the landscape which is called Tsongkha ("Onion Valley") by Tibetans. It has a total area of 13,100 square kilometres (5,100 sq mi).

Climate

[edit]

Haidong has a cool semi-arid climate (Köppen BSk) characterised by warm to very warm summers, freezing but extremely dry winters, and large diurnal temperature ranges. Temperatures are warmer than anywhere else in Qinghai due to the relatively low altitude, although minima in winter still typically fall below −10 °C or 14 °F. Precipitation is low and mostly confined to the summer months: less than 45 millimetres or 1.8 inches of water equivalent typically falls between October and April inclusive, and less than 12 millimetres or 0.5 inches between November and March.

from Grokipedia
Haidong (Chinese: 海东市; : Hǎidōng Shì) is a in northeastern Province, Northwest , located east of and deriving its name from this position, literally meaning "east of the sea." It spans an area of 13,200 square kilometers and had a resident population of 1,328,600 as of 2024. Upgraded to prefecture-level city status in 2013 from its prior role as a prefecture, Haidong functions as a key gateway to Qinghai Province, bordering Gansu Province to the east and adjacent to the provincial capital Xining to the west. The region boasts a history of human settlement dating back over 6,000 years, with archaeological evidence from the Neolithic period and significant development during the Sui and Tang dynasties as part of the ancient Hehuang area, a cradle of multi-ethnic cultures. Ethnically diverse, it is home to Han Chinese, Hui, Tu, Salar, and Tibetan populations, fostering a blend of Islamic, Buddhist, and traditional folk traditions evident in sites like the Youning Temple and Gautama Temple. Geographically, Haidong features rugged mountains, fertile valleys, and semi-arid plateaus at elevations of 2,100 to 4,300 meters, supporting natural attractions such as the Mengda National Nature Reserve, which spans 93 square kilometers of diverse forests and wildlife. Economically, it relies on agriculture (including highland barley and potatoes), animal husbandry, and burgeoning tourism, while emerging industries like renewable energy and logistics benefit from its strategic position along major transport routes connecting Xining to inland China.

History

Ancient and medieval periods

The Haidong region exhibits evidence of human occupation dating back approximately 6,000 years to the period, with settlements linked to the Majiayao culture in the upper valley. Archaeological findings from sites in eastern , such as pottery shards, ground stone tools, and faunal remains, reveal early mixed economies of millet farming and animal herding, including domesticated pigs, sheep, goats, and dogs. These communities are associated with proto-Qiang populations, who developed semi-sedentary lifestyles adapted to the plateau's riverine environments. During the ancient period, the area faced influences from nomadic confederations, notably the , who subjugated Qiang tribes around the early Han era (circa 200 BCE), compelling tribute and fostering alliances or conflicts that shaped regional power dynamics. By the 7th-8th centuries CE, Haidong—then known as Shanzhou—became a strategic frontier under oversight, integrated through military garrisons and diplomatic ties with the (Tubo). The 641 CE marriage of Tang Princess to Tibetan King symbolized this integration, promoting tea-horse trade along routes, though control oscillated amid wars, culminating in Tubo's temporary conquest of Shanzhou in 757 CE during the . In the medieval era, the (1271–1368 CE) incorporated the into its vast following Mongol conquests, establishing administrative units to oversee pastoral economies and extensions along the , blending Mongol, Han, and Tibetan governance. The subsequent (1368–1644 CE) reinforced these routes with fortifications and guard posts (wei-so) to counter Oirat Mongol threats, while formalizing local administration amid ethnic diversity. Notable sites include the Ruins in Minhe County, a settlement (circa 2000 BCE) preserving Qiang-linked artifacts like millet stores and skeletal remains from a catastrophic flood, offering insights into prehistoric disaster resilience; and the Chiling at Sun-Moon Mountain, erected in 729 CE to commemorate Tang-Tibetan peace accords and trade pacts, underscoring Haidong's role in cross-cultural exchanges.

Modern establishment and development

During the Republican era (1912–1949), the Haidong region, located in the fertile Huangshui River valley of eastern , fell under the control of the , a group of Hui Muslim warlords who dominated the province through military governance from . initially seized power in 1912 following the fall of the , establishing a base in the region and using it as a hub for agricultural production and trade, with annual pastoral product exchanges valued at around 800,000 silver liang by the 1920s. His nephew, , who became governor in 1938, intensified control over eastern , promoting agricultural intensification in lowland valleys like those around Ledu and Minhe counties through irrigation improvements and colonization efforts, though these were limited compared to western initiatives. Land reforms under the Ma regime focused on reclaiming "wastelands" for farming, but they often prioritized Hui and Han settlers, exacerbating tensions with local Tibetan pastoralists. Conflicts with Tibetan forces were frequent, culminating in the 1932–1933 Yushu Borderland War, where 's troops repelled a Tibetan invasion of 5,000–6,000 soldiers, reclaiming southern territories and reinforcing 's borders through a in June 1933. These military campaigns, including earlier expeditions in 1917, 1921, and 1925, secured the Ma clique's hold on Haidong as an economic and strategic core, while fostering Hui-dominated administration and education systems, such as the expansion of Muslim schools from 56 in 1931 to over 90 by 1934 under the Islam Progressive Council. Following the establishment of the in 1949, Haidong was integrated into Province as part of broader administrative reforms, with the Qinghai Provincial People's Government formed in 1950 to oversee the region's incorporation. In the , several key counties were established or reorganized to consolidate control and promote socialist development: Ledu County in 1954, Ping'an County in 1958, and Huzhu Tu Autonomous County in 1954, among others, reflecting national efforts to delineate ethnic autonomous units for Hui and Tu populations while integrating Tibetan areas. These divisions emphasized land redistribution through democratic reforms, redistributing estates from former holdings to peasants and cooperatives, which boosted agricultural output in the Huangshui valley. The (1966–1976) severely disrupted local governance in Haidong, a multi-ethnic area with significant Hui and Tibetan communities; mosques were destroyed or repurposed, Hui faced including pig-raising mandates and public humiliations, and Tibetan religious sites were ransacked, leading to social upheaval and economic stagnation as targeted "feudal" elements in minority customs. Recovery began in the reform era after 1978, with Deng Xiaoping's policies enabling the reopening of mosques and restoration of ethnic autonomy, alongside initial market-oriented agricultural adjustments that stabilized rural economies in Haidong by the . Development accelerated in the 2000s through national infrastructure initiatives, particularly the launch of the Western Development Strategy in 2000, which funneled investments into eastern Qinghai's transport networks. The , operational from 2006, significantly enhanced connectivity for Haidong, reducing travel times to and facilitating trade in agricultural goods, with regional accessibility improving markedly and supporting urbanization in counties like Ledu. This infrastructure boom, including road expansions and irrigation upgrades, laid the groundwork for economic diversification beyond subsistence farming. In 2013, Haidong was upgraded from a prefecture-level region to a full on February 8, marking its emergence as an independent administrative entity and accelerating ; this status shift detached several suburban districts from Xining's direct influence, enabling focused growth with a of about 1.7 million and emphasizing eco-development projects funded by institutions like the . Post-2013 economic policies centered on targeted poverty alleviation under China's national campaign, which lifted over 80 million rural poor nationwide by 2020; in Haidong, initiatives included photovoltaic installations in villages like Yangjiashan in Ledu District to generate income through clean energy subsidies. These efforts promoted sustainable livelihoods in ethnic minority areas, fostering Haidong's transition to a hub for , , and .

Geography

Location and topography

Haidong City is situated in the eastern part of Province, , at geographic coordinates of approximately 36°30′N 102°00′E. It serves as a key transitional region, bordering City to the west, Province (including Gannan and Linxia Prefectures) to the east, and Hainan Tibetan Autonomous Prefecture to the south, while Haibei Tibetan Autonomous Prefecture lies to the north. This positioning makes Haidong a vital link between the and the Qinghai-Tibet Plateau, spanning a total area of 13,200 km². The of Haidong features a diverse dominated by plateaus in the central and eastern areas, transitioning to the foothills of the in the north. Elevations vary significantly, ranging from around 1,800 meters in the lower river valleys to over 4,000 meters in the higher mountainous zones, creating a stepped that descends westward toward the provincial capital. This varied profile influences local , with lower areas supporting denser settlement and higher slopes remaining more rugged and sparsely vegetated. Geologically, Haidong is underlain by soils in the plateaus and alluvial deposits in the valleys, which facilitate through fertile sediments but also heighten risks of and landslides due to the region's steep gradients. The area lies within a seismically active tectonic setting on the northeastern margin of the , intersected by active fault lines such as extensions of the Haiyuan fault system, contributing to elevated seismic hazards that necessitate ongoing monitoring and efforts. As the eastern gateway to Province, Haidong's topography offers a relatively accessible entry to the province's broader high-altitude terrain, contrasting with the more extreme elevations found further west.

Hydrology and natural features

Haidong's hydrology is dominated by the (Huang He), which forms the southern boundary of the region and serves as its primary waterway, supporting irrigation, transportation, and ecosystem services across the . The river's main stem in Province spans 1,694 km overall, with a significant portion traversing Haidong's southern counties such as Minhe and Hualong, where it receives major tributaries like the Huangshui River and the Datong River. The Huangshui River, the largest tributary in the area, measures 374 km in total length, with 226 km within Qinghai and 139.2 km specifically in Haidong, contributing an average annual runoff of 2.15 billion cubic meters and an average flow of 61.68 m³/s at the Ledu hydrological station. These waterways harness substantial potential in the upper basin, where projects like the nearby Yangqu Hydropower Station exemplify the region's capacity for generation, with installed capacities reaching into the gigawatt scale across Qinghai's segments. Lakes and wetlands further enrich Haidong's aquatic systems, with the Liujiaxia Reservoir on the —straddling the Qinghai-Gansu border near Hualong County—providing critical water storage, flood regulation, and sediment control over an area exceeding 130 km². Smaller saline lakes and riverine wetlands, totaling about 268 km² in the Huangshui River basin as of 2009, play vital ecological roles, including serving as stopover sites for migratory birds such as waterfowl and shorebirds during seasonal passages along the flyway. These wetlands support diverse aquatic flora like reeds (Phragmites spp.) and cattails (Typha spp.), while also mitigating and enhancing water quality in the basin. The region's natural features include concentrated in mountainous uplands, covering approximately 6% of Haidong's land area as natural (76,500 ha in ), alongside broader green coverage rates up to 38% in like Ledu and Ping'an through integrated belts. Expansive grasslands dominate the plateaus and valleys, facilitating traditional practices and sustaining economies, while hotspots harbor endemic species such as indigenous fish from the family (e.g., Schizothorax spp.) and common avifauna. Environmental challenges persist, particularly in the hilly terrains, where agricultural and dry lands account for over 50% of eroded areas, with annual soil loss rates exacerbated by slope gradients of 55-80° in cliff zones. Conservation initiatives, including under China's Grain-for-Green Program since 1999 and riparian greening projects, have stabilized slopes across thousands of hectares, reducing by up to 1,119 tons per year in targeted areas and bolstering ecosystem resilience.

Climate

Climate classification and data

Haidong experiences a cold (Köppen BSk), characterized by low and significant temperature fluctuations due to its high-altitude continental plateau location. The annual average ranges from 300 to 500 mm, mostly concentrated in the summer months, primarily influenced by the East Asian monsoon. Data from the Ledu District meteorological station, a key monitoring site in the region, indicate an annual average temperature of approximately 7°C over the period 1991-2020, with monthly averages showing lows around -10°C and highs reaching 25°C. Historical records reveal extreme temperatures in the region, including a record low of -25.1°C and a high of 33.5°C. For Ledu specifically, the recorded low is -20.9°C (2016) and high 38.4°C (2000). Since the , observations show a warming trend, with annual mean temperatures increasing by approximately 0.3-0.4°C per decade, consistent with broader patterns across the Qinghai-Tibet Plateau driven by global . Recent observations up to 2023 indicate continued warming and slight increases (about 4.3 mm per decade since 1961), exacerbating risks in semi-arid zones. This data, derived from long-term meteorological observations at Ledu and surrounding stations, provides a baseline for assessing environmental conditions in Haidong. Microclimatic variations are pronounced across Haidong's topography, with valleys along the Huangshui River exhibiting milder temperatures (up to 8.6°C annually) and slightly higher due to orographic effects, while higher plateaus and northern mountains are cooler (down to 3.2°C) and drier. These differences influence local , where semi-arid conditions limit crop yields in highlands but support valley-based farming with .

Seasonal patterns and extremes

Haidong, situated in a semi-arid zone, exhibits pronounced seasonal variations influenced by its plateau location and proximity to river valleys. In spring from to May, the region experiences dry winds and occasional storms as temperatures rise from around -4°C to 10°C, melting and leading to early seasonal floods in lower valleys. These conditions challenge early agricultural activities, with events reducing visibility and depositing fine particles on croplands. Summer, spanning June to August, brings the East Asian monsoon, accounting for approximately 70% of Haidong's annual through intense rains that can total 61-70 mm monthly in areas like . Temperatures range from 9°C to 25°C, fostering growth but posing risks of landslides in the mountainous terrain, particularly along the Huangshui River basin where heavy downpours erode slopes and disrupt infrastructure. Autumn from to offers cooler and more stable weather, with temperatures dropping to 1°C-19°C and varying from 1-99 mm, making it ideal for harvests of crops like and . However, early frosts can occur in higher elevations, potentially damaging late-season yields. Winter, to , features harsh cold with temperatures as low as -14°C to 5°C and minimal of 2-7 mm, often as covering highlands and impacting practices by limiting access to . Historical extremes include severe blizzards on the Qinghai-Tibet Plateau during this period, such as those in the late 2000s that caused significant livestock losses across the region. To mitigate these seasonal challenges, local adaptations include expanded systems along the Huangshui River to combat spring droughts and summer variability, as well as the promotion of drought-resistant crop varieties like highland barley and potatoes to enhance resilience in semi-arid conditions.

Administrative divisions

Structure and counties

Haidong was established as a on February 8, 2013, through a State Council approval that revoked the former Haidong Region, created Ledu District from Ledu County, and retained five counties: Ping'an County, Minhe Hui and Tu Autonomous County, Huzhu Tu Autonomous County, Hualong Hui Autonomous County, and Xunhua Salar Autonomous County. On February 16, 2015, the State Council further approved the revocation of Ping'an County to establish Ping'an District, resulting in the current structure of two districts and four autonomous counties. As a , Haidong operates under the direct administration of the provincial government, managing local governance, public services, and development initiatives across its subdivisions. The administrative divisions are detailed below, reflecting their ethnic autonomous status where applicable to promote cultural preservation and equitable representation for minority groups such as the Hui, Tu, and Salar peoples.

These divisions form the foundational framework for Haidong's , with counties ensuring policies align with ethnic minority needs under China's regional ethnic system. Population distribution varies, with Ledu and Ping'an districts hosting the largest shares due to urban concentration.

Urban and rural areas

Haidong's urban areas are centered primarily in Ledu District, the prefecture's administrative seat, where ongoing development has led to expanded infrastructure and modern facilities, including the Haidong City Exhibition Hall completed in 2022 to showcase regional growth and integration. Projects like the Ledu Chaoyang Mountain comprehensive park support relocation and development across Haidong since its upgrade to prefecture-level status in 2013. Ping'an District also contributes to urban expansion. in Haidong has accelerated, rising from 24.4% in 2011 to 40.4% in 2020, driven by industrial and residential construction along the Huangshui River valley.
