Abstract:In this paper, we construct the framework of ecosystem comprehensive
   evaluation index system using Driver - Pressure - State - Impacts -
   Response (DPSIR) conceptual model. The evaluation model is established
   using the correspondence analysis method, maximizing deviations methods
   and grey relational method. The contributions of this paper come from
   four aspects. Firsty, we constructed index system using DPSIR conceptual
   framework, and bring human demand, economic development and social
   progress into the system. It is much better than the existing researches
   which only consider the status of environment and resources or the
   status of environmental protection and pollution treatment. Second,
   based on the correspondence analysis, we apply the R and Q factor
   analysis simultaneously to the provinces and the indicators, using the
   least dimensions to show most of the information. Third, through the
   graph of correspondence analysis, we acquired a distinctive ecosystem
   project. To reach the aim which enhances the level of environment
   effectively, different provinces should improve different indicators.
   And we analyze the af-finitive indicators is good or bad for each
   province. Fourth, through adding natural disaster index into the
   pressure layer of the index system, the paper described the effect of
   natural disaster on ecosystem. This improved the existing DPSIR model
   which only considered the effect of human activity on ecosystem.
