天山北坡经济带城市人居环境质量与城市化水平协调性评价

Coordination Evaluation Between Urban Human Settlement Environment Quality and Urbanization Development of the Economic Belt on the North Slope of Tianshan

从城市的居住生活条件、生态环境质量、基础设施与公共服务质量、社会和谐度4个方面构建评价体系,对天山北坡经济带2014年的城市人居环境质量进行了评价,结果表明:研究区内城市人居环境质量整体偏低且两级分化较明显,人居环境质量的协调度指数反映出近一半城市子系统间的反馈关系不强;利用ArcGIS从宏观角度反映研究区的城市人居环境质量的空间差异特征:东疆哈密地区、吐鲁番地区的水平较低,伊犁地区的水平最高,以乌鲁木齐经济圈为中心向外辐射的一系列城市的人居环境质量较高。经定量分析,得出影响城市人居环境质量的主要因子包括:人口密度、人口自然增长率、人均居住面积、人均道路铺装面积、人均绿地面积、建成区绿地覆盖率;以城市人居环境在城市化进程中的优化配置程度为标准,可将城市分为4种类型:经济环境协调模式(高—高型),环境滞后模式(高—低型),经济滞后模式(低—高型),经济环境双滞后模式(低—低型),结合影响因子分别对4类城市的人居环境改善进行讨论,为今后进行"以人为本"为原则的城市建设提供相关建议。

The evaluation system used to analyze the urban human settlement environment quality of the economic belt on the north slope of Tianshan in 2014 was constructed from 4aspects：the living conditions,the ecological environment quality,the infrastructure and public service quality,the degree of social harmony.The result showed that urban human settlement environment qualities in the research area are overall poor and obviously extreme.The coordination index reflects there are weak feedback relationships between every subsystem in nearly half of cities.The ArcGIS provides a macro point of view to reflect the spatial variability of urban human settlement environment quality in the research area,in the east of Xinjiang,the urban human settlement environment quality level is low,such as Hami and Turpan area,the highest level appears in Ili,series of cities with high quality take Urumqi Economic Circle as the center.The main influence factors found by quantitative analysis include the population density,the population growth rate,the living space area per capita,the road pavement area per capita,the green area per capita and the built-up green area coverage rate.The coupling model was constructed to evaluate the optimization level between urban human settlement environment quality and the urbanization level,which can be divided into 4modes：the economic-environment coordinated mode（high-high）,the environmental lag model（high-low）,the economic lag model（low-high）,and the economic-environment lagged model（low-low）;Combined with the influence factors,4types of cities are discussed on the improvement of the urban human settlement environment,which can provide somesuggestion for city construction on people-oriented principle in the future.
