龙江县位于黑龙江省西部,地处大兴安岭南麓,大兴安岭与松嫩平原过渡地带,丘陵起伏,漫川漫岗,由于地势原因,水土流失非常严重。流失耕地255万亩,占全县总面积的26%。形成发展性侵蚀沟5 420条,总长17 000公里,吞噬良田122万亩,严重影响粮食的高产和稳产。为解决这一重要矛盾,龙江县在治理水土流失,特别是对发展性侵蚀沟的治理上进行了深入的研究探索。
Longjiang County is located in the western Heilongjiang Province, located in the southern foot of Daxinganling, Daxinganling and Songnen Plain transition zone, rolling hills, diffuse Manchuang, due to topographical reasons, soil erosion is very serious. 255 million mu of arable land loss, accounting for 26% of the total area of the county. A total of 5 420 developmental erosion ditches have been formed, covering a total length of 17,000 km and phagocytying fertile fields of 1.22 million mu, seriously affecting the high yield and stable yield of grain. In order to solve this important contradiction, Longjiang County conducted in-depth research and exploration on the control of soil and water loss, especially on the governance of the developmental erosion ditch.
