【摘要】：河湖水系连通是当前重要的水利发展战略,是改善水资源配置、抵御水旱灾害、进行生态环境治理的重要手段,对其影响的评价能为决策提供重要的依据。本文首先讨论了河湖水系连通生态环境影响评价不同于其他水工程影响评价的若干方面,指出在进行河湖水系连通生态环境影响评价时,连通区独特的空间结构导致反映同一内涵的指标在受水区、调水区及整个连通区均可能存在阈值,从而可能需要在多个区域上评价连通的影响;其次,本文提出了在连通区上评价连通对生态环境指标影响的概念模型及基于这种概念模型进行评价的方法;最后,本文讨论了本概念模型的局限性以及河湖水系连通影响评价研究需进一步开展的工作。
[Abstract]:The connection of rivers and lakes is an important development strategy of water conservancy at present. It is an important means to improve the allocation of water resources, resist flood and drought disasters, and manage the ecological environment. The evaluation of its influence can provide important basis for decision making. In this paper, several aspects of Eco-environmental impact assessment of river and lake systems are discussed, which are different from those of other water projects, and it is pointed out that in the process of ecological environmental impact assessment of connected river and lake systems, The unique spatial structure of the connected region leads to the existence of threshold values in the water receiving region, the water transfer area and the whole connected area, which may result in the need to evaluate the impact of connectivity on multiple regions. Secondly, this paper puts forward a conceptual model for evaluating the impact of connectivity on ecological environmental indicators on the connected region and a method based on this conceptual model to evaluate the impact of connectivity on ecological environmental indicators. Finally, this paper discusses the limitations of this conceptual model and the further research work needed to be carried out on the evaluation of the connectivity of rivers and lakes.
