广东省典型水土流失区不同植被措施的减水减沙效益分析——以石马河小流域为例

Benefits of Different Plants on Reduction of Water and Sediment Yield in Typical Soil and Water Loss Area of Guangdong Province—As a Sample in Shima Small Watershed

植被措施是广东省水土流失区最常用的一种水土保持措施。以石马河小流域为例对不同植被治理措施的减水、减沙效益进行野外监测与分析对比 ,表明不同类型和结构的植被群落与减水、减沙效益之间有较明显的差异。并分析了降雨特征对不同植被措施的减水、减沙效益的影响。综合评价了石马河小流域治理后的水土保持效益。

Vegetation measure is one of the most useful and basic methods to harness the typical soil and water loss area of Guangdong province. As a case in Shima small watershed, the benefits of different plants on reduction of water and sediment yield were compared. The result showed that the plant colonies of different type and stucture brought different benefits. The influence of rain to the different reduction benefits was also analysed. The synthetical benefits of soil and water conservation after harness in Shima small watershed are evaluated.
