柴草河小流域水土保持治理措施探讨

MANAGEMENT MEASURE SOIL AND WATER CONSERVATION IN CHAICAOHE WATERSHED

柴草河小域内地势复杂、坡陡沟多 ,水土流失严重。通过对不同地形坡度的改造整治 ,从下到上依次为基本农田、经济林、水保林和植草的分层种植模式 ,配套相应的水利工程措施 ,土地重新规划、部分退耕还林还草等方法 ,基本实现了泥不下山、溪水常流 ,控制了水土流失 ,改善了生态环境 ,对山区小流域治理有普遍的指导意义。

The topo of Caicao river is very complicated. There are too much cliffy slope and big ravine. The erosion of soil and water is very serious. Different alterations are made to slope with different angle. Base cropland, water conservation hurst and anti-drought grass are adopted from the bottom to the top of the mountain. And corresponding managements were conducted, such as build irrigation works, plowland reprogramming and partly return the cropland to the nature. By these means the erosion of soil and water are basically controlled. The environment was improved obviously. It has directive significance to the integrated management in drainage area.
