The City's Ecosystem Evaluation Model Based on Optimal Combination Weights and Its Application
摘要
Abstract
Based on the typical and high frequency indicators of the united nations commission on sustainable development、 The world bank and other authorities, according to the present situation of lacking statistical data in China、the observability principle and scientific development concept of" insisting on the concept of people-oriented , comprehensive, coordinated and sustainable development" , and at last establishes the ecosystem evaluation index system which was applicable to prefecture-level cities. This paper established ecosystem evaluation model based on optimal combination weighting and analyzed the ecological conditions for 14 typical cities in Liaoning province as empirical analysis. The innovation and features of this paper came from the four aspects; firstly, through putting green GDP per capita, unit load of industrial waste water and other indicators into the " driver-pressure-state-impacts-response" framework to build the ecosystem evaluation index system which could be applied to prefecture-level cities. Secondly, through optimal combination weight this paper achieved the goal that generalized distance between every evaluation object's weighted score and ideal point was least, reflecting the theory that the evaluation object away from the ideal point closer, higher score the evaluation object got. Thirdly, by introducing the maximum entropy principle of Jaynes, determining the optimal combination weighting coefficient based on the i-dea of the largest consistency of evaluation results. Thus, this paper avoided the problem of the unreasonable single weighting method making too little contribution to the combination weighting. Fourthly, the empirical results showed that "population growth rate"、'units of water resources in industrial waste water load"、"water resource per capita" and " " green GDP per capita" were the indicators which impacted ecological development most of Liaoning province.关键词
