干旱区风力发电建设区域水土流失量测评
Assessment of Soil Erosion in Wind Power Construction Areas in Arid Regions

针对地处新疆木垒县大石头200 MW第五风力发电项目，实施建设区域土壤侵蚀和水土流失及自然修复期水土流失防止效果监测评估。采用资料收集、现场勘查、遥感监测现场测试测算结果表明，建设工程涉及土壤侵蚀面积71.93 hm2，由于工程建设新增水土流失量约6.65 kg/m²。新增水土流失量大小顺序：施工及检修道路 > 风电机组区 > 继电线路区 > 施工生产生活区 > 送出线路区 > 升压站区，说明施工及检修道路区对水土流失量影响大。建设完成后二年半自然修复期监测评估显示，水土流失面积由71.93 hm²，减少到 47.32 hm²，治理修复率65.8%，治理修复程度以年均11%递增，水土流失防止效果明显。
Implement monitoring and evaluation of soil erosion and soil erosion in the construction area, as well as the prevention effect of soil erosion during the natural restoration period, for the 200 MW fifth wind power generation project located in Dashitou, Mulei County, Xinjiang. The results of data collection, on-site investigation, and remote sensing monitoring on-site testing and calculation show that the construction project involves a soil erosion area of 71.93 hm2, with an additional soil erosion of about 6.65 kg/m² due to the construction project. The order of the magnitude of newly added soil erosion is: construction and maintenance roads > wind turbine area > relay line area > construction production and living area > transmission line area > booster station area, indicating that construction and maintenance road areas have a significant impact on soil erosion. After two and a half years of natural restoration monitoring and evaluation, the area of soil erosion decreased from 71.93 hm² to 47.32 hm², with a remediation rate of 65.8%. The degree of remediation increased by an average of 11% per year, and the prevention effect of soil erosion was significant.
