辽西荒漠化区域水土流失敏感性评价——以彰武县衙门小流域为例

Sensitivity Evaluation for Soil and Water Erosion in Desertification Area in Western Liaoning Province——Taking the Yamen small catchment in Zhangwu County as the example

文章以彰武县衙门小流域作为研究对象,通过研究分析,确定了该小流域主要生态环境的敏感区域。探究结果表明:该地区各级的敏感地区交错进行,与人类活动的范围基本一致,人类活动的越多越集中的地区越是敏感,流域内约73%的敏感区。

Taking the Yamen small catchment in Zhangwu County as the objective studied,this paper determined the sensitive area of main ecological environment in the small catchment. It appears that the sensitive areas distribute crossly in this area with each grade,and are basically in line with the specturm of human activity,more sensitive in area where more human act more concentrated,accounting for 75%of the sensitive areas within the catchment.
