黄土区地貌部位对植被水土保持效应的影响

Influence of Geomorphic Locations on Soil and Water Conservation of Vegetation in Loess Region

本研究综述了近几年国内有关不同地貌部位(塬坡和沟坡)植被的保水和减沙效应。重点对两种类型坡面的不同植被下土壤含水量和产沙量进行了比较,初步总结了分别适宜于塬坡和沟坡,且能够同时产生较好的保水和减沙效益植被类型。并进行了相应的展望。

This study reviewed the water retention and sediment reduction effects of vegetation on different landforms (plateau slopes and ditch slopes) in China in recent years. The soil water content and sediment yield under different vegetation on the two types of slopes were compared, the vegetation types that were suitable for plateau slopes and ditch slopes which could produce better water conservation and sediment reduction benefits were preliminarily summarized, and a corresponding outlook was given.
