【摘要】：中广核阜新万德号风电场处于辽宁省西北部地区生态环境比较脆弱的阜蒙县，该区域水土流失问题较严重。因此对该建设项目开展水土保持评价工作不仅是关乎民生的一件重要的事，，对促进国民经济和社会发展更是起到了重要的作用。 本文根据风电场现有资料以及场地状况，完成了对研究区水土保持评价、预测、防治以及监测等研究工作，主要内容如下： （1）对工程占地、土石方平衡、工程建设对水土流失的影响以及防治范围和责任等方面进行分析评价，在满足施工需要的前提下，尽量减少临时用地，有效减少施工扰动范围和施工引起的水土流失。 （2）确定水土流失预测范围、方法以及参数，对工程项目可能造成的水土流失范围、水土流失量、水土流失危害进行预测。预测时段内，研究区原地貌情况下产生水土流失量为655.41t，如不采取水土保持措施，预测时段内可能产生的水土流失量为1585.03t，新增水土流失量为929.62t。 （3）对研究区的风电机组防治区、升压站防治区、场内道路防治区、集电线路防治区、施工临时用地防治区5个防治分区进行了工程措施、植物措施、临时措施三个方面进行了措施布设，形成了系统全面的水土保持防治措施体系。 （4）根据水土流失预测结果明确6项水土流失防治指标：扰动土地治理率、水土流失治理度、土壤流失控制比、拦渣率、植被恢复系数和林草覆盖率，为后续水土保持工作奠定基础。
[Abstract]:Fuxin Wande wind farm is located in Fumeng county where the ecological environment is relatively weak in northwest Liaoning Province. The soil and water loss problem is serious in this area. Therefore, the evaluation of soil and water conservation is not only an important issue related to people's livelihood, but also plays an important role in promoting the development of national economy and society. According to the existing data of wind farm and site condition, this paper has completed the research work of soil and water conservation evaluation, prediction, prevention and control and monitoring in the study area. The main contents are as follows: (1) balance of earth and rock, The influence of engineering construction on soil and water loss, the scope and responsibility of prevention and control are analyzed and evaluated. On the premise of meeting the needs of construction, the temporary land use is reduced as far as possible, and the scope of construction disturbance and the soil erosion caused by construction are effectively reduced. (2) to determine the prediction range, method and parameters of soil and water loss, and to predict the range of soil and water loss, the amount of soil and water loss, and the harm of soil and water loss. In the prediction period, the amount of soil and water loss produced under the original geomorphological condition is 655.41 t. If the measures of soil and water conservation are not taken, the possible amount of soil and water loss in the period of prediction is 1585.03 t, and the new amount of soil and water loss is 929.62 t. (3) Engineering measures and plant measures are carried out in five prevention and control zones of wind turbine, booster station, road, power collecting line and temporary site of construction in the study area. The prevention and cure area of wind power unit, the prevention area of booster station, the prevention and cure area of collecting electricity line and the prevention area of temporary land for construction are carried out. The temporary measures were arranged in three aspects, and a systematic and comprehensive system of soil and water conservation measures was formed. (4) according to the prediction results of soil and water loss, 6 indexes of soil erosion control were defined: disturbance land control rate, soil erosion control degree, soil loss control ratio, sediment retention rate, vegetation restoration coefficient and forest and grass coverage. To lay a foundation for the follow-up work of soil and water conservation.
