摘要

该研究借鉴国内外森林保土效益研究的成功经验，结合河北省山地土壤流失特点，首次计算出了河北省山地森林年保土总量为6266.15万t;减少废弃土地面积9640.24hm

减少泥沙滞留1590.64万m

减少泥沙淤积1156.84万m

减少土壤有机质损失271.32万t

减少N、P、K损失130.24万t

经价值计算得出河北省山地森林年保土效益为38.15亿元，平均每年每hm

山地森林保土效益为1957.5元。

Abstract

Based on the analysis of research on forest protecting soil in home and abroad

combining with the characteristics of soil runoff in Hebei Province

the datas were calculated.The soil conservated is 62 661.5 thousand t/a

the decrease of deserting land is 9640.24hm2

preventing of mud and sand 15906.4 thousand m3

depositing mud and sand 11568.4thousand m3

the loss of soil organic matter 2713.2 thousand tons

the loss of N

P and K 1302.4 thousand tons.The total economic value is 3.815 billion Yuan

that means 1957.5Yuan /hm2.
