摘　　要：针对城市生态系统健康评价问题,提出一种基于粗糙集和信息熵的指标体系建立方法.根据城市生态系统健康评价相关指标数据建立信息系统,运用信息熵定义知识重要性,以核为起点进行属性约简,构建评价指标体系.该方法从实际数据中求得的指标体系能够客观评价城市生态系统健康状况,为城市发展提供准确和快捷的决策依据.According to the evaluation of city ecosystem health, a method for index system establishing based on rough and entropy was proposed. The information system of city ecosystem health was built depending on the data of relevant evaluation index. By using entropy, and taking the core as starting point, the attribute reduction was finished and the evaluation index system was constructed. This method of establishing the index system from actu- al data can objectively evaluate the condition of city ecosystem health and provide accurate and quick basis for city development decision.
