| 摘 要： | 该研究借鉴国内外森林保土效益研究的成功经验，结合河北省土地土壤流失特点，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＾２，减少泥沙滞留１５９０．６４万ｍ＾３，减少泥沙淤积１１５６．８４万ｍ＾３，减少土壤有机质损失２７１．３２万ｔ，减少Ｎ、Ｐ、损失１３０．２４万ｔ，经价值计算得出河北省山地森林保土效益为３８．１５亿元，平均每年每ｈｍ＾２山地森林保土效益 |

| Abstract: | According to the annual abservation results in 1990-1996 on man-made bare slope in Kongshan mountain ous area of south Jiangsu province,the process and affecting factors of natural recovery of vegetation are analysed. The natural recovery process of vegetation began in 1991 (the year after the formation of mam -made bare slope).In 1996,the natural recovery process of vegetation was finished and soil erosion stopped.It is put forward that the prevention of soil erosion on man-made bare slope can not be realised only by the natural recovery process of vegetation.It is necessory to take other countermeasures to prevent soil erosion. |
| Keywords: | man-made bare slope soil erosion natural recovery of vegetation |
