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。
River and Lake System Interconnection(RLSI) is an important strategy employed presently for water resources management.It is also a key measure for improving the capacity of water resources allocation,enhancing flood and drought control and improving eco-environment.The evaluation of the environmental and ecological impacts of RLSI can provide a good basis for the decision-making concerning RLSI.In this paper,several aspects of the impact evaluation of RLSI different from those of other types of water projects were discussed.It was pointed out that the specific space structure of the connected region may result in multiple threshold values of an environmental or ecological impact evaluation index.A conceptual model was proposed for the evaluatlon of the environmental and ecological impacts of RLSI in the whole connected region,as well as the evaluation method based on this model.The limitations of the conceptual model and the perspectives in the impact evaluation of RLSI were discussed finally.
