Hulun Lake National Nature Reserve is located in the northeast of Inner Mongolia Autonomous Region and the west of Hulunbeier city. It is located in the border area of China, Mongolia and Russia. The reserve covers four administrative regions, namely, new balhu Right Banner, new balhu Left Banner, Manzhouli City and zalainoer district. It is 164 kilometers away from Hailar District, the capital of Hulunbuir city. It is 41 kilometers away from Manzhouli City, the largest land port in China. It is 14 kilometers away from alatanemole town in the West and 50 kilometers away from Amugulang town in the East Latitude 47 ° 45 ′ 50 ″ ~ 49 ° 20 ′ 20 ″; longitude 116 ° 50 ′ 10 ″ ~ 118 ° 10 ′ 10 ″.
The reserve is located in the eastern end of Eurasian steppe, which belongs to temperate continental climate. The annual average temperature is - 1.3 ℃ - 0.4 ℃, the extreme maximum temperature is 40.1 ℃, the extreme minimum temperature is - 42.7 ℃; the effective accumulated temperature of 10 ℃ is 2336-2675 ℃; the frost free period is 110-160 days; the average annual precipitation is 247-319mm and the average annual evaporation is 1636mm.

Hulun Lake is a huff and puff lake on Hulunbeier high plain, ranking the fifth largest lake in China. It is an irregular oblique rectangle from northeast to southwest. The length of the lake is 93 km, the average width of the lake is 32 km, and the maximum width is 41 km. The slope of the west side of the lake near the cliff is large, and the north, East and south sides are relatively gentle. The deepest point is in the center of the lake basin to the West. At high water level, the lake water flows into the Erguna River along the Xinkai River and Dalan Oromu River and flows into the Okhotsk Sea, which is a freshwater lake; at low water level, it becomes an inland lake with slightly salty (or brackish) water. The water replenishment of Hulun Lake mainly comes from the Wuerxun River, the Kelun River, the natural precipitation, the runoff around the lake and the natural inflow of groundwater. Due to the large area and shallow water depth of the lake, evaporation consumption is more. In history, the highest water level of Hulun Lake was 545.33 meters in 2000. The largest area of Hulun Lake is 233900 hectares, the maximum water depth is 8 meters, the average water depth is 5.7 meters, and the water storage capacity is 13.85 billion cubic meters. Since 2000, due to the continuous decline of precipitation in the surrounding areas, the water inflow of Wuerxun River and krulun River, the main supply rivers of Hulun Lake, has decreased sharply. From 2000 to 2012, the total inflow of the two rivers was 4.05 billion cubic meters, with an average annual average of 310 million cubic meters, which was only 1 / 4 of the annual average value. The amount of water entering the lake was only 1 / 6 ~ 1 / 7 of the evaporation, resulting in the continuous decline of lake water level. From 2000 to 2012, the water level of Hulun Lake dropped from 544.4 meters to 540 meters, the water area decreased from nearly 2200 square kilometers to 1750 square kilometers, and the water storage capacity decreased from 14 billion cubic meters to 4.5 billion cubic meters. After the project of "diverting water from the river to the lake" was put into operation in 2009, the water level in the lake area was still lower than the average water level for many years until 2013.
Due to the fact that the Kelun River and the Wuerxun river carry about 250000 tons of sediment into the lake every year, coupled with the collapse of the lakeshore caused by strong wind and waves, there is about 50 cm thick sediment deposition at the bottom of Hulun Lake.
Beier lake is a freshwater lake shared by China and Mongolia. It is oval in shape, 40 km long and 20 km wide, covering an area of 60878 hectares. 4026 hectares in the northwest are owned by China and are all in the reserve. Generally, the depth is about 9 meters, and the deepest part of the lake can reach more than 50 meters.
Xindalai lake is formed by the breach of Hulun Lake with an area of 14700 hectares. It is located about 9 kilometers northeast of ganzhuhua and 5 kilometers away from Hulun Lake in the West. With the decline of Hulun Lake water level, xindalai lake was cut off from Hulun Lake in 2001 and dried up in 2006.
WuLanNuoer is located 80 kilometers south of Hulun, which is the water surface formed by the tributaries of Wuerxun river. When the water is big, it is 15-17 km long from east to west, 2-5 km long from north to south, covering an area of 3200 ha. In dry season, it becomes a swamp. It dried up in 1996 and recovered to its original appearance after ecological engineering treatment in 1997.
The Kelun river is located in the southwest of Hulun Lake. It originates from the south foot of Kent mountain in the people's Republic of Mongolia, and flows into Hulun Lake from west to East. The total length of the river is 1264 km and the width is about 40-90 M. It is 206.44km long in China and less than 20km in nature reserve.
Wuerxun river originates from Beier lake, flows into Hulun Lake in the north, connects Hulun Lake and Beier Lake in North and south, and connects left and right grasslands of new balhu from east to west, with a total length of 223.28 km and drainage area of 10528.27 km2. The width of the river varies with the amount of water. In the wet season, the river width is generally 60-70 meters, and the water depth is 2-3 meters.
The halaha river originates from darbin Lake in the Western foot of jiligexian in the south of Daxing'an Mountains. It flows from southeast to northwest and flows to the vicinity of ebudugkalun, which is divided into two branches, one flows into the Wuerxun river through the sallejin River (dried up) to the northwest, and the other flows into Beier Lake in the south.
It is a tributary of the halaha River, which is 41.19 km long before it flows into the lake bell. It is a 52 km long tributary. In the Urxun River, it flows 24.07 km from the bell lake to the Urxun river. The sharejin river connects halaha River and Wuerxun River directly, forming a triangle area through which the boundary line of China and Mongolia passes. Among them, the area of the Shahe River Basin in China is 5175 hectares.

Xinkai River is an artificial river connecting the old roads at both ends of Dalan Oromu river. It starts near Shasha mountain in the east of Hulun Lake in the south, bypasses Zhalainoer mining area and railway station in the East, crosses Binzhou railway, reaches the foot of Heishantou in the northwest, and joins the old river course of the lower reaches of Dalai Luomu River, with a total length of 16.4 km. The width of Xinkai River bottom is bounded by railway, 15 meters to the South and 22 meters to the north. On the Xinkai River near Shasha mountain in the east of Hulun Lake, a sluice gate was built to control the fluctuation of lake water; on the Xinkai River south of Binzhou railway line, an outlet flood gate was set up to prevent Hailar River from flowing back into the lake at high water level.
The artificial river channel connecting Hulun Lake and Hailar River was put into operation in 2009, which played a key role in curbing the trend of water level decline in Hulun Lake.
There are some seasonal rivers and lakes in Hulun Lake water system, which are distributed around Hulun Lake.
There are two kinds of seasonal lakes. One is the lake bubble connected with Hulun Lake, with good water quality. There are xindalai lake, songhatuo lake, arendormo lake, wudulupao lake and jibuqi fish circle Lake; the other one is not connected with Hulun Lake, but the water surface changes with the change of Hulun Lake water level, with small area, high salinity and more distribution on the West Bank of Hulun Lake.
The seasonal rivers around Hulun Lake converge into the lake in the season of heavy rainfall. There are mainly the following rivers: Hulun ditch, Shuiquan ditch, dashajuan River, Xishan Valley and laono.4 ditch.

The regulations are divided into five parts: General principles, planning and protection, utilization and management, legal responsibility and supplementary provisions. The reserve is divided into core area, buffer area and experimental area. Among them, the core area is a well preserved natural ecosystem and the concentrated distribution area of rare and endangered animals and plants, and no unit or individual is allowed to enter without authorization; the periphery of the core area is the buffer zone, which is only allowed to engage in teaching, scientific research and observation activities, and is forbidden to carry out tourism and production and business activities; the periphery of the buffer zone is an experimental area, which can carry out scientific experiments, teaching practice and participation Observation and investigation, tourism, domestication, reproduction of rare and endangered wild animals and plants, and appropriate production and management activities.
The large area grassland of Hulun Lake National Nature Reserve in Inner Mongolia is the most typical and complete middle temperature grassland ecosystem preserved in China. It preserves the structural characteristics of typical grassland animal and plant communities to the maximum extent, and has an ancient history of flora and community occurrence. The reserve also has vast water area and wetland. Hulun Lake is the largest freshwater inland lake in northern China. It is a paradise for many birds to inhabit and breed. It is also an important distribution center for bird migration in Northeast Asia. It is also an ideal place for bird ecology research and lake ecosystem evolution. At the same time, the reserve is also a rich gene bank of natural species resources and a repository for saving and protecting species, which has high scientific research value.
