摘要

根据已有的土壤侵蚀评判模型

对黑河水库汇流区进行了单元划分与侵蚀强度评判

评判结果与实测及已有研究吻合较好

得出了汇流区内土壤侵蚀强度的空间分布

指出土壤侵蚀与土地利用密切相关

退耕还林是减轻汇流区土壤侵蚀和延长水库寿命的根本途径。

Abstract

On the basis of developed soil erosion model on the middle and east part of Guanzhong plain

the soil erosion intensity and their units are estimated in Heihe basin. The relative error between the exist results and field survey of hydrographic stations were in the allowed duration. The spacial distribution of soil erosion intensity were shown and the relationships between soil erosion intensity and land use types were discovered in the Heihe basin. Adjusting land use structure and reconstructing vegetation ecosystem would be basic way for reducing soil erosion and prolonging the lifetime of Heihe reservoir.
