摘　　要：论文首先建立了城市人居环境宜居性评价指标体系,体系包括自然环境和社会经济环境两个子系统,继而下面又分了8个评价因子和38个评价指标。另外根据目前我国的环境质量标准和有关文明城市、生态园林城市建设标准以及相关文献等对指标体系进行了等级划分,即分为5个等级,并制定了评判标准。同时引入BP神经网络模型,以临沂市为例,采用1998～2006年间数据来进行实证研究。该模型可为量化城市人居环境质量之间的差距作参考。Evaluation index system of city inhabitable environment quality was established, which includes two subsystems as natural environment and socioeconomic environment, orderly as 8 factors and 38 practical evaluation indexes.
