松嫩平原低湿地在黑龙江省松花江沿岸及低地平原区广泛分布,长期垦植使其相对独立的生态系统遭到破坏,导致区域生态环境较差,农业生产基础脆弱。黑龙江省木兰县位于松花江中游北岸,沿松花江低湿地区域3.6万hm~2,低湿易涝面积2.52万hm~2,其中防洪大堤34hm~2,堤外面积8000hm~2,堤内面积1.72万hm~2,防风防浪林带169.7hm~2,堤内耕地1.67万hm~2,鱼塘210hm~2,荒地73hm~2,荒水23hm~2。针对低湿地区域易涝面积大,生产潜力高,生态环境和水利工程较差状况,木兰县提出了以改善生态环境为本,以提高系统整体功
The lowland wetland of Songnen Plain is widely distributed along the Songhua River and the lowland plain of Heilongjiang Province. The long-term cultivation has destroyed the relatively independent ecological system, resulting in poor ecological environment and weak agricultural production foundation. Heilongjiang Mulan County is located in the north bank of the middle reaches of the Songhua River, along the Songhua River low wetland area of 36,000 hm ~ 2, low humidity flooding area of 25,200 hm ~ 2, flood control embankment 34hm ~ 2, embankment area 8000hm ~ 2, embankment area of 17,200 hm ~ 2, 169.7 hm ~ 2 for windbreak and rain forest, 16.7 thousand hm ~ 2 for arable land in dikes, 210 hm ~ 2 for fish ponds, 73 hm ~ 2 for wasteland and 23 hm ~ 2 for barren water. Aiming at the problems of large flooding area, high production potential, poor ecological environment and water conservancy projects in low-wetland areas, Mulan County proposed to improve the ecological environment in order to improve the overall system work
