| 摘 要： | 基于RUSLE对沂沭泗河流域的土壤侵蚀进行定量研究,确定土壤侵蚀风险区域。研究结果表明:该流域土壤59.297%为微弱侵蚀,15.65%为中度侵蚀,主要分布于沂沭泗河流域土壤侵蚀的重点风险区域和重点治理区沂蒙山区;人类合理的活动在减少土壤侵蚀中发挥重要的作用。研究结果为该区域控制水土流失提供了基础数据。

| Abstract: | This study used the revised universal soil loss equation(RUSLE) technique to assess soil loss and identify risk erosion areas in Yishusi River catchment.The results showed that 59.297% of the catchment fell within minimal erosion category and 15.65% the moderate erosion category,mainly distributed in the important soil erosion risky areas and Yimeng mountainous area of Yishuisi River catchment.The reasonable human activities played an important role in decreasing soil erosion.The study provided basic data for controlling the soil erosion in this area. |
