基于DPSIR模型的成都市生态可持续发展评价

为了监测评价城市的生态可持续发展水平，需要建立一套科学的指标体系并选择合理的评价方法。在介绍国内城市生态可持续发展评价研究现状的基础上，根据DPSIR模型的原理，从驱动力、压力、状态、影响及响应5个方面建立成都市生态可持续发展评价指标体系，并采用改进熵值法对指标进行赋权，计算出2001年-2010年间成都市生态可持续发展综合评价指数。根据计算结果对成都市生态可持续发展程度和存在的主要问题进行了具体分析，并提出相应的对策措施。

Evaluation of Sustainable Ecological Development in Chengdu City Based on DPSIR Model

In order to monitor and evaluate the level of sustainable ecological development in cities, a scientific index system should be established with a reasonable evaluation method. Based on evaluation researches of domestic urban ecological sustain- able development, this paper establishes a comprehensive evaluation index system of Chengdu City from five aspects of driving force, pressure, state, impact and responses, according to the principles of DPSIR model. The improved entropy method is used to define the scale of each index and calculate the comprehensive evaluation index in the years from 2001 to 2010. According to the evaluation resuhs, this paper analyzes the level of ecological sustainable development in Chengdu as well as the existing prob- lems, and then puts forward the countermeasures.
