摘要

山东省的水土流失危害主要有:增大河流的洪枯比

土壤肥力降低、质地变粗

土层变薄

基岩裸露

库坝河湖严重淤积

洪涝风雹等自然灾害频繁等

加重了居民的贫困。小流域治理

减轻了水土流失

提高了生态经济效益;提高了土壤肥力

增加了农地的产量;发展了商品生产

Abstract

Harm from soil erosion in Shandong Province are seen mainly in theincrease of rate of flood to dryness

the lowering of soil fertility

thecoasening of texture

thinning of soil layer

the naking of bed rock

thesever deposition in reservior

river and lake

the frequent natural disasters like flood

water logging

wind and hail

ect.

which makes the residents more poor. But the harness of small watershed produces goodresults that soil erosion is lighted

the benefit of ecological economyraised

soil fertility improved

farm yield raised

commodity production developed

and the multiple benefits of economy increased.
