| 摘 要： | 利用USLE方程和径流场对大姚县水土保持生态修复区土壤侵蚀进行监测,旨在探讨采取退耕还林、封禁、坡改梯等修复措施后,土地利用变化对修复区土壤侵蚀的影响.研究结果表明：高强度土壤侵蚀主要发生在坡耕地特别是陡坡耕地,而林地和梯地少有发生;经过退耕还林增加林地面积和坡改梯后,土壤侵蚀现象得到缓解,流失面积减少2 867.35 hm^2.

| Abstract: | Using the USLE and runoff sits to monitor the soil erosion for the ecological recovery region on the dayao county, the effect of the land use change on soil erosion were be discussed after those recovery measures have been used such as converting land for forestry, turning slope-land into terraced land and closing hillsides management and so on . According to the monitoring datum, the intense erosion used to be taking place in slopcultivated land especially on steep-slop-cultivated land and little taking place in woodland or terraced land. In the end of the ecological recovering pilot engineering, the soil erosion has been abated and 2 867.35 hm2 soil loss area has been reduced by converting land for forestry to add woodland area and turning slope-land into terraced land to decrease loss intensity on recovery region. |
