摘要

嘉陵江中下游水土流失严重，是全国水土保持重点防治区，该文通过典型流域李子溪的径流、泥沙等资料分析得出：近10年，该流域由于对生态环境的治理和保护，水土流失呈下降趋势，多年平均输沙量1985～1994年较1965～1984年减少58.3%.因此，若将该流域治理水土流失的经验和措施推广到嘉陵江中下游其它地区，该区严重的水土流失定将得到明显改善。

Abstract

The middle and lower reaches of Jialingjiang river with a serious soil erosion

is a major region of soil and water conservation in the whole country.A conclusion is obtained by analyzing the documents of runoff and sediment in Lizixi basin

a typical basin of the reaches.Because of taking control and protect measurement into the ecological environment

soil erosion in the basin shows a tendency to decrease in a recent decade.Comparing with sediment discharge in years from 1965 to 1984

sediment discharge from 1985 to 1994 reduced 58.3%.Therefore

if the experience and measurement of controlling soil erasion of the basin are spread to other areas of the reaches

the condition of serious soil erosion in the middle and lower reaches of Jialingjiang river will be distinctively improved
