摘　　要：水土保持效益评价是水土保持科学体系中的重要内容。本文讨论了指标体系的选取原则和方法,分析了"国标"的优劣,提出了区域水土保持效益评价指标体系,同时介绍了常用的效益计算和评价方法,最后对效益评价的未来趋势进行了展望。The evaluation of the benefits of soil and water conservation plays an important role in the scien- tific system of soil and water conservation, and has become one of the most popular topics with both scien- tists and conservationist. This paper systematically analyzed the present research situation and problems on the benefit evaluation of soil and water conservation. And then, the paper suggested a regional--scale evaluation parameter system. Meanwhile, the prevalent methods of benefit evaluation were introduced. Fi- nally, we looked ahead the trend of the research on benefit evaluation.
