摘要

水土保持是城市森林生态效益中最重要的一项

它是森林其它各种效益的基础。传统上研究和考察森林水土保持效益时

一般从土壤侵蚀角度出发

忽视了对水损失的考察。着重从水的损失出发

提出了用森林水保持率、水土保持率来考察城市森林的水土保持功能

并对北京、伦敦的城市森林和河南山区水保林的水流失率、水保持率进行了论证比较。

Abstract

Soil and water conservation is an important ecological service of forest systems.To determine the effectiveness of forests in soil and water conservation

the loss modulus of soil and water is often employed.However

this is an imperfect concept.The authors advanced a new theory for the assessment of soil and water conservation

specifically presented an analysis of not only soil loss rate and water loss rate

but also soil and water loss rate.
