【摘要】：近几年来,抽水蓄能电站建设给社会带来巨大经济效益和社会利益的同时,也不可避免的在一定程度上破坏了人类赖以生存的自然资源与生态环境,对人类后续发展产生较大影响。水电站的水土流失问题已经逐渐成为一个需要重点关注的问题,如何在工程建设中尽量减小对当地环境的破坏,保障经济可以持续发展,是当今研究的重要课题。本文以安徽绩溪抽水蓄能电站建设为例,对该水电站建设造成水土流失问题进行研究。首先,分析预测抽水蓄能电站建设对当地植被破坏、地表扰动的影响,分析工程布局、施工工艺、弃渣场选址、施工组织设计、施工管理以及对主体工程水土保持分析,复核工程建设确实无水土保持限制性因素;在水土流失防治分区的基础上,对不同的地区进行针对性的分析,并考虑该地区在工程中的用途,预测潜在水土流失问题及其危害;在此基础上,提出不同区域水土保持方法,对不同措施体系布局,进行植物种植区域选定,建立临时防护措施。根据工程项目技术参数与设计要求,提出具体的水土保持方法。最后,预测实施的水土保持效果,结果表明,该研究方法表明本文水土流失防治研究方案能很好的控制水土流失情况,使得各项指标都能达到目标需求。并对该项目实施提出了针对性建议,在保证工程正常运营下,能够最大限度进行水土保持。从水土保持角度,本研究各项水土流失防治指标均能达到方案防治目标要求,不但可以有效治理工程区水土流失及其危害,而且一定程度上恢复生态环境,并同时具有一定的生态效益、社会效益和经济效益。
[Abstract]:In recent years, the construction of pumped storage power station has brought great economic benefits and social benefits to the society, but also inevitably destroyed the natural resources and ecological environment on which human beings depend for survival. It will have a great impact on the subsequent development of human beings. Water and soil erosion of hydropower stations has gradually become an important issue to be paid attention to. How to minimize the damage to the local environment and ensure the sustainable development of the economy is an important research topic in the engineering construction. Taking the construction of Jixi pumped Storage Power Station in Anhui Province as an example, the problem of soil erosion caused by the construction of this hydropower station is studied in this paper. First of all, it analyzes and predicts the influence of the construction of pumped storage power station on the local vegetation, the surface disturbance, the layout of the project, the construction technology, the site selection of the waste site, the construction organization design, the construction management and the analysis of the soil and water conservation of the main project. On the basis of the zoning of soil and water loss prevention and control, the paper analyzes the different areas and forecasts the potential soil and water loss problem and its harm by considering the use of the area in the project. On the basis of this, the methods of soil and water conservation in different regions are put forward, the layout of different measures system, the selection of planting area and the establishment of temporary protective measures are carried out. According to the technical parameters and design requirements of the project, the concrete soil and water conservation methods are put forward. Finally, the effect of soil and water conservation is forecasted. The results show that the scheme of soil and water loss prevention and control can control soil and water loss very well and make every index meet the demand of the target. Some suggestions are put forward for the implementation of the project, which can maximize the soil and water conservation under the normal operation of the project. From the point of view of soil and water conservation, every index of soil and water loss prevention and control in this study can meet the requirements of the control plan, which can not only effectively control soil erosion and its harm, but also restore the ecological environment to a certain extent. And at the same time has certain ecological benefit, social benefit and economic benefit.
