发展沟道人工湿地 改善基岩产沙区生态

随着沟道坝系工程建设的开展 ,黄土高原基岩产沙区出现了一些沟道湿地迹象。发展沟道人工湿地对于改善区域农业生态环境、增加生物群落、净化环境和水源等具有重要意义。鉴别和确认湿地的类属有利于湿地的研究、利用、保护和发展。依据我国湿地的定义、界定条件及类型等 ,对黄土高原基岩产沙区沟道治理形成的湿地进行了确认 ,并指出了其发展前景

Developing ArtificialWetland in Gully, Improving Ecological Environment

With the development of dam system works in gully construction, a certain quantity of “wetland”indications in gully have occurred in the area of sediment yield from base rock of loess plateau. To develop the artificial wetland in gully is of great importance to improving ecological environment of regional agriculture, increasing biological community, purifying environment and water source etc. To distinguish and confirm wetland's categories is of benefit to the wetland's research, utilization, protection and development. According to the wetland's definition, boundary condition and categories etc., the wetland formed by gully harnessing in the area of sediment yield from base rock of loess plateau has been confirmed and pointed out its developing prospects.
