戈壁荒漠区风电场建设对水土流失的影响

Effects of Wind Power Site Construction in Gobi Desert Area on Soil and Water Loss

以酒泉市戈壁荒漠区的9个已建成的典型风电场为研究对象,通过收集资料与现场监测相结合的方法获取了该项目的工程性质、占地面积、挖填方量及施工工艺等资料,应用水土流失影响指数计算、分析和评级方法,计算了戈壁荒漠区风电场建设的水土流失影响指数,建立了国内荒漠戈壁区风电场项目的水土流失影响指数众值范围。通过计算得出,戈壁荒漠区风电场建设的水土流失影响指数为0.314 0。

By taking nine typical wind power sites built in the Jiuquan gobi desert for an example,impacting index of soil and water loss for wind power site construction in the gobi desert area was calculated and a range of impacting indexes for the gobi desert areas in China was determined through the calculation,analysis and grading of the impacting index of soil and water loss.The data like engineering properties,cover area,excavation and embankment volume and construction technology involved in the project were obtained by combining data collecting with in-situ monitoring.It follows from the calculation that the impacting index of soil and water loss for wind power site construction in the gobi desert area was 0.314 0.
