深圳市观澜河流域水土流失规律研究

STUDY ON THE REGULARITY OF SOIL EROSION AND WATER LOSS IN GUANLAN WATERSHED OF SHENZHEN CITY

深圳市观澜河流域地处南亚热带,受自然因素和人为因素的影响,流域存在着严重的水土流失,改革开放以来,流域的大片土地被开发成了工业开发区。工业开发区在建设阶段,机械夷平土地所形成的各种松散的堆积坡,引起了新的水土流失类型。本文研究和探讨了该流域的水土流失规律及水土流失对流域水环境的影响。

The Guanlan Watershed in Shenzhen City is located in the south subtropical zone. Under the effects of natural and human factors, there are serious soil erosion and water loss in this watershed. Since the implementation of 'open and reform' policy, the vast land has been developed into industrial exploiting zones. At the primary stage of the construction of the industrial exploiting zones, the various loose slopes produced by levelling the ground with machines induced new kinds of soil erosion and water loss. The regularity of soil erosion and waterless and their influences on the hydro—environment in Guanlan watershed are discussed in this paper.
