【摘要】：以南水北调工程为例的输水管道工程在解决我国水资源供需矛盾和地域分配不均的问题中发挥着重要作用,输水管道工程的建设在产生巨大社会、经济、生态效益的同时,也给工程建设区域、调水相关区域脆弱的生态环境带来新的问题。工程建设的环境影响评价往往关心工程建设、运行时期对相关区域内主要环境要素的影响、响应及评价,而对工程建设相关的关键生态系统的影响关注较小。而南水北调等输水管道工程是与水密切相关的国家级大型工程,对工程建设区域、影响区域的水生生态系统产生较大的影响,如何科学、定量地评价输水工程对关键生态系统的影响是输水工程建设管理人员关注的热点之一。基于对生态需水评价理论与方法的总结及输水工程生态影响定量评价难点的分析,对生态需水与水生生态系统健康之间相辅相成的关系进行研究,提出了将生态需水引入输水工程生态影响评价的技术路径与评价模型。以南水北调中线工程为例,对其影响范围内的生态需水量进行评价,进而判断工程建设运行对相关区域关键生态系统的影响。
[Abstract]:Taking the South-to-North Water transfer Project as an example, the water pipeline project plays an important role in solving the contradiction between the supply and demand of water resources and the uneven distribution of water resources in China. The construction of the water pipeline project is producing a huge society and economy. At the same time, ecological benefits also bring new problems to the fragile ecological environment in engineering construction areas and water transfer related areas. The environmental impact assessment of engineering construction is often concerned about engineering construction. The impact, response and evaluation of the main environmental factors in the relevant areas during the operation period. However, the impact on the key ecosystems related to engineering construction is relatively small. However, the South-to-North Water transfer pipeline project is a large national project closely related to water, which has a great impact on the construction area of the project. The aquatic ecosystem of the affected area has a great impact on it, and how to be scientific. It is one of the hotspots for water conveyance project construction managers to evaluate quantitatively the influence of water conveyance project on key ecosystem. Based on the summary of ecological water demand evaluation theory and method and the difficulty of quantitative evaluation of water conveyance project ecological impact. The analysis. The relationship between ecological water demand and aquatic ecosystem health was studied. This paper puts forward the technical path and evaluation model of ecological water demand in the ecological impact assessment of water conveyance project. Taking the middle route of South-to-North Water transfer Project as an example, the ecological water demand within its influence range is evaluated. Furthermore, the influence of engineering construction on the key ecosystem of relevant regions is judged.
