感潮河湖水系连通水环境改善效果评价

河湖水系连通作为解决水环境问题的一个重要措施，其实施对于改善感潮河网地区水环境具有重要作用。为评价感潮河湖水系连通工程实施后水环境的改善效果，提出了一套评价指标体系及评价方法，包括结构性评价指标体系、水动力评价指标体系、水质评价指标体系等3个方面，分别定量评价河湖水系连通对于河网水系结构、河网水动力和水质的改善效果，以及河网水环境的综合改善效果。通过实地调查与测验资料，利用所建立的指标体系对广州市海珠区感潮河网水系连通工程实施后的水环境改善情况进行了评价，验证了该方法的可行性和实用性。

Effect evaluation upon water environment improvement by river system network connecting construction in tidal river area

The river-lake system connection is an important strategy for solving the water environment problem and its implementation has important significance to the water environment improvement in tidal river area. In order to assess the improvement effect of water environment in tidal area by implementing the water system connecting works, a set of assessment index system and assessment method are put forward, the system includes the structural assessment system, water dynamic assessment system and water quality assessment system, which assess the improvement effect of river network structure, river network water dynamic and water quality respectively as well as the comprehensive water environment improvement effect. By the assessment index system and the field investigation and measured data, the water environment improvement effect in tidal river area of Haizhu district, Guangzhou City after river network system connecting works is assessed. The feasibility and practicability of assessment are proved.  
