城市可持续发展的指数普适公式及评价模型

An Exponential Universal Formula and Evaluation Model of Sustainable Development for Cities

为了建立城市可持续发展的评价模型 ,分析了社会、经济和环境指标体系所具有的特征 ,提出了基于GA优化的分类单项指标的发展指数普适公式 ,并采用广义对比运算和层次分析法对不同层次指标赋权 ,建立了社会、经济和环境可协调持续发展评价模型 .该模型应用于大理市的可协调持续发展评价结果表明 :基于GA优化参数后的分类单项指标的发展指数公式和评价模型不仅简单、实用 ,而且具有可比性。

In order to study an evaluation model of sustainable development for cities, analysis was performed to study the features of indicator system of community, economy and environment. Based on the genetic algorithms optimum, an exponential universal formula of single indicator was proposed. Evaluation model of sustainable development about the coordinative development of community, economy and environment was developed using weightting method combining the general contrast algorithm with analytic hierarchy process for different structure. The evaluation results of sustainable development for examples using this model showed that the exponential formula of single indicator based on parameters optimum and the evaluation model are not only simple and practical, but also comparisonable, realizable and general.
