摘　　要： 回顾了国内关于具有优良水土保持性能的草本植物的系列研究,认为当前筛选出的水土保持型草种主要集中于禾本科,也包括豆科、桑科的少数种;其应用范围多见于公路边坡和坡耕地,缺乏对其水土保持效果持久性的评价。今后应针对各类受损生态系统的立地条件,加强优良野生草种的筛选与利用,探讨并建立多草种组合及草灌间植的模式,提高水土保持效益。 Based on summarizing various studies on grass species with excellent soil and water conservation property in China, this paper pointed out that most of these species belonged to Gramineae family while only a few were Lejuminosae family or Moracae family, which were mainly applied in slope of highway and cultivated land with gradient. It also indicated that comment on durability of grass of erosion prevention was absent. As a result, according to all kinds of conditions of destroyed ecosystem, both the selecting and breeding of good wild grass species and cultivated design of grass species union and intercrop of grass and shrub should be increase in the soil and water conservation, which will improve the soil and water conservation.
