5) vegetation cover
植被
1.
Because of the effects of plant roots on soil infiltration and anti-scourability,the time of runoff be- ginning becomes longer with the increase of the vegetation coverage.
植被根系提高土壤渗透性和抗侵蚀性,植被盖度越大径流起始时间越长,植被提高边坡的入渗率和减少土壤流失相互促进,共同作用的结果是保持水土,所以植被增加边坡降雨入渗的作用是十分显著的。

补充资料：配置效率和生产效率
在经济学上，经济发展的动力，或者说效率的来源，分为两类：一类是配置效率，二是生产效率。所谓配置效率，是指给定资源和技术的条件下，怎么样使资源从边际生产率低的地方流向边际生产率高的地方，从而使得资源和利用更合理、社会总价值达到最大;而生产效率是指如何通过技术进步提高每一种资源的生产率，也就是把社会的生产可行性边界向外移。
