摘　　要：在对县域城镇居民生活质量评价指标进行甄别的前提下,从影响居民生活质量的6个方面,选取了23个二级指标,通过综合加权求和模型,采用GIS空间分析方法,以县域为空间单元研究了宁夏19个县域城镇居民生活质量的空间分异格局并对其进行了相应的解析。研究结果显示:1)居民生活质量综合得分最高(>0.5)的城市仅有银川市(0.62885),宁夏城镇居民生活质量整体水平偏低;2)宁夏19个县域城镇居民生活质量总体呈现出北高南低的空间分异特征,与社会经济发展水平格局基本吻合;3)各分指标的空间分异态势不尽相同;4)环境指标得分在空间格局上表现出独有的南高北低态势。This research identified the evaluation system and discussed the indicator weight of quality of urban life in county scale firstly, then selected the 23 secondary indexes from 6 aspects that affect the quality of urban life. Using the model of comprehensive weighted summation and GIS spatial analysis methods, the spatial differ- entiation pattern of quality of urban life for 19 counties in Ningxia province was studied, and the causes were ex- plored. The results showed that ： ① The quality of urban life of Yinchuan city achieves the optimal level, howev- er; there are 12 areas still below average level; the overall of quality of urban life in Ningxia province is at low level. ② Quality of urban life of 19 counties in Ningxia province take on the characteristic as follow ： it is high in north area, low in south area, and is consistent with the pattern of social and economics developmental level. ③ The environmental indicators show a unique characteristics as follow： high in south area and low in north area.
