| 摘 要： | 在漳卫河流域山区历次遥感调查数据的基础上,通过分析区域内土壤侵蚀强度时空变化,在时间序列上明确了区域内土壤侵蚀总体变化、强度等级变化特征.结果表明：漳卫河流域山区土壤侵蚀情况明显好转,轻度以上土壤侵蚀面积逐渐减少,土壤侵蚀强度较高等级逐渐向较低等级转化,流域土壤侵蚀状况得到改善.

| Abstract: | Based on the existing remote sensing data of mountain areas of Zhangwei River Basin, spatial and temporary changes of soil erosion intensity in the area were analyzed, the time-series characteristics of overall changes and intensity grade changes of soil erosion were clarified consequently. It can be indicated that the statue soil erosion of Zhangwei River Basin was obviously improved in general,soil erosion intensity and above-light erosion areas were decreased gradually, the soil erosion status of Zhangwei River Basin was improved. |
