North and south part of the Wandashan the Sanjiang Plain is divided into two parts north and south: North Hill is the Songhua, Heilongjiang and Ussuri confluence of low marsh alluvial plain, an area of 42,500 square kilometers, which is narrow in the Sanjiang Plain; Shannan is the Ukraine Suriname River and its tributaries, together with the formation of alluvial Xingkai - swamp low lacustrine plain, an area of 8800 square kilometers, also known as Muling - Xingkai plain.

narrow the Sanjiang Plain in Heilongjiang River Basin, part of the mountain, surrounded by mountains, west young offshoot Xiaoxing'anling Montenegro, south watershed Kong offshoot Wanda, Wanda east main vein That Dan Hada Ling, is a fault in the Cenozoic inland. Folded basement in accumulated on the complex more than a kilometer, the Cenozoic sedimentary cover, the thickness of the Quaternary of 120 to 200 meters, the thickness of up to 280 meters. In addition to the surface east of 3 to 17 m thick clay layer, the main alluvial sand and gravel, as the pore-rich groundwater aquifers. 45 ~ 60 meters above sea level, the lowest Fuyuan River only 34 meters, gently sloping from southwest to northeast, with a total gradient of about 0.10 ‰, in the broad river meandering river floodplain. Major landform types terraces and floodplain along the western and southern edges of the skirt, red, alluvial sloping plain, in different types and more slow transition, the same type of surface relief is generally only 0.5 to 2 meters, the plain only see a few isolated hill residual hill, widespread shallow dish and linear depressions, cut slightly, with the exception of Heilongjiang, Songhua, Ussuri River, the small and medium rivers are all plain swamp river, and mostly covered by swamp vegetation. Muling - Xingkai plain bordering the north and south of Wanda, the West is Ken Tee Ling. Quaternary alluvial sediments in the area, lacustrine sand and gravel-based, 10 ~ 150 meters thick, the surface of 1 to 4 meters thick clay cover. 55 ~ 95 meters above sea level, north, west, 10 to 20 meters high wavy poor, with a total relief from west to east slope, slope 0.6 ~ 0.1 ‰, Muling flood land and lake beaches broad common ground swamp. Sanjiang Plain, the climate is temperate humid and semi-humid continental monsoon climate, annual sunshine hours 2400 to 2500 hours, January average temperature of -21 ~ -18 ℃, 7 monthly average temperature 21 ~ 22 ℃, frost-free period of 120 to 140 days, 10 ℃ accumulated temperature more than 2 300 ~ 2 500 ℃. Freeze for up to 7 ~ 8 months, the maximum frost depth of 1.5 to 2.1 meters. Annual precipitation of 500 to 650 mm, 75 to 85% concentrated in the 6 to 10 months. Sanjiang Plain, a vast low-lying landscape topography, precipitation, moisture concentration of the cold summer Hou, runoff is slow, the river burst peak, and seasonal freezing and thawing of the soil is heavy clay, the surface to promote long-term too wet, too much water, the formation of large area of swamp and marsh vegetation water

, soil, marshes constitute a unique landscape. Swamp and marsh land area of about 240 million hectares, is the largest distribution area of the swamp. Wet and marsh plants are angustifolia, marsh willow, sedge and reed. Among the most widely distributed Carex swamps, marshes accounted for about 85% of the total area, followed by reed swamp. Soil types are black, white slurry soil, meadow soil, swamp soil, etc., but the meadow soil and marsh soil most widely distributed. Sanjiang Plain in order to After Reclamation built many large state farms, State of the environment now, the Sanjiang Plain, environmental conditions are good, the majority of forests, rural areas and most of the farms are clean air quality standards; except some sections outside the natural water quality is good. Natural wetland area still 1.347 million hectares, is an important habitat for rare water birds and breeding grounds have been built six state-level wetland nature reserve, of which three were included in the list of wetlands of international importance, the protection of endangered birds are red-crowned crane and the Swan.

Soil types are black, white slurry soil, meadow soil, swamp soil, etc., but the meadow soil and marsh soil most widely distributed. Sanjiang Plain in order to After the founding of the PRC, where the Farm on a large scale farming, has established four state Farm Bureau, more than 50 large-scale state farms,
nike air force 1 high, more than 4,600 mu of cultivated land, In addition, the Sanjiang Plain is also rich in bird resources and peat resources. At the same time, the ecological balance in this area has been a certain degree of damage, deterioration of climatic conditions, early flood disasters increase, increased wind damage, serious soil erosion, reduction of rare animals and plants. In the future should be rational use of natural resources, promote agriculture, forestry, animal husbandry, and fishery development, mainly waterlogging, floods and droughts Kaneharu, improve irrigation and water conservancy construction, the establishment of marsh landscape and rare birds, rare species of nature reserves. Its characteristics are: surface water are generally 10-15 cm, the length of weed, locally known as 40 cm. Distribution of a large area in Sanjiang Plain of China's most fertile black soil, organic matter content is high,

is a fault with the river inland. It is the first Paleozoic metamorphic rocks, Paleozoic and Mesozoic sedimentary rocks of the basement, the Tertiary depression (fault) and the formation of the basin. Sanjiang Plain, low and flat, sloping from southwest to northeast, with an average altitude of 50-60 meters, the Fuyuan River Island black blind the lowest elevation of 34 meters. The total surface slope 1 / 10000. Residues scattered in the mountains on the plains and residual hills, such as Crouching Tiger Li Shan, do not pull audio Hill, Street, Jin Shan, Dadingzishan and so on, their height more than 500 meters, mainly from the Paleozoic, Mesozoic shale, acidic volcanic rocks and granite composition. Sanjiang Plain harvest harvest most people aspire to, in the vast field, the channel aspect, agricultural machinery roar, rice flower fragrance, rolling waves of grain, a level of mechanization of leading the modernization of the country farms, vibrant, busy and well-off.

Annual output of 15 million tons of grain in Sanjiang Plain, the per capita area of cultivated land per capita food production are more than four times the national average. There is huge agricultural production, agricultural mechanization in the nation. Meanwhile, a beautiful environment within the region, pollution is very small, in the Sanjiang Plain wetlands have been reduced significantly curb the trend, above the level reached 10 wetland nature reserves by the international ecological, environmental organizations, concern and support.
