摘　　要：陇东地区西平铁路甘肃段降雨量相对丰富,取土场取土后汇水面积大,形成有效径流时间短且流量大,径流资源利用匮乏,植被建设不够合理。本研究拟通过充分利用取土场取土结束后形成特有地貌和研究区丰富的降水资源,采用分级削坡型取土场边坡生态治理修复技术与高陡边坡生态治理修复技术模式,构建陇东地区取土场水土资源利用体系,加速修复取土场建设对区域生态环境造成的破坏,有效抑制取土场建设造成水土流失。Precipitation is relatively rich in the Gansu Section of Xiping Railway.After soil borrowing,it often results in large areas of water impoundment that shortens the time of having effective runoff and large flows and the vegetation cannot be properly arranged due to the lacking of effective runoff.The study has concentrated on special landform as results of soil borrowing and how to take the advantage of rich rainfall resources.Technologies are exploited for the recovery of cascade and slope-cut soil collection sites and models of high steep slope ecological restoration,in order to build land and water resources utilization system for soil collection sites in the east of Gansu Province,take quick measures for repairing damages caused by soil borrowing and soil erosion and restoring local eco-environment.
