Abstract
The existing methods of the water environmental quality assessment generally focus on the environmental characteristics, and fail to cover the core demands of ecological demonstration project. These methods lack a comprehensive analysis of sustainable development and maintenance capabilities. Also, the subjective analysis and computing of weight furthermore leads to unstable output. This paper is written in attempt to raise a set of assessment systems and methods to evaluate the demonstration projects of water environment. With the helping of establishing a complete quality evaluation index system of water environment demonstration project, the research approaches are based on the model of subjective and objective comprehensive weighting evaluation of DEMATEL-EVM. Through this method, it is able to analyze the key elements scientifically, which influence the water environmental project, finally makes the assessment more convincible.

Summary
1.1 Research Situation of Evaluation of Water Environment Demonstration Projects. Theories of assessments of water environment demonstration projects are still in the gradually perfect stage. Most of assessments applied in the water pollution treatment use the fuzzy comprehensive evaluation method, which is the combination of Analytic Hierarchy Process (AHP) and DEMATEL. It is difficult to achieve an objective evaluation of the running of projects merely depended on the evaluation of water pollution treatment, because large demonstration projects involve other factors, like ecological and economic benefits. The results of water pollution treatment should be evaluated comprehensively according to the improvement of ecological rehabilitation, national economic benefits and many other standards. The current large projects evaluation system can cover the whole construction stage and zoom analyze every node in the projects, projects on environmental governance still lacking mature theoretical system. There are still not enough attention paid on the management and monitoring on the later period, as well as the after-evaluation of the projects
