摘要

采用彩色红外航片

结合野外实地调查

编制了安塞县纸坊沟流域1∶1万的土壤侵蚀类型图。该图详细反映了流城内土壤侵蚀类型的定位关系。土壤侵蚀类型的面积清单

可为水土保持综合治理评价与规划提供基础数据。制图结果表明

该流域经过综合治理

土壤水蚀强度已由治理前的极强度侵蚀类型下降为中度侵蚀类型。

Abstract

In applicatioa of color infrared aerophoto and combining with ground truth investigation

we worked out the map of soil erosion type (1: 10

000 scale) of Zhifanggou watershd in Ansai County. The map of soil erosion type shows thoroughly the space relationship of the soil erosion type.The detailed area list of soil erosion type may serve for the evaluation and planning of soil and water comprehepsive conservation. The soil erosion intensity of Zhifanggou watershed befor comprehensive control is very intensive erosion type. Through comprehensive control

the soil erosion intensity reduce to medium erosion type.
