泛长株潭城市群各市区人居环境的评价与优化

Evaluation and Optimization of Human Settlement Environment in Pan Chang-Zhu-Tan Urban Agglomeration

通过GIS,RS及其他多种信息源获得相关数据资料,运用熵值法,对泛长株潭城市群进行人居环境指数和协调度的综合评价,评价结果表明:长沙处于最宜居弱协调状态,株洲、湘潭和常德处于次宜居弱协调状态,衡阳处于次宜居勉强协调状态,岳阳处于次宜居一般协调状态,娄底和益阳处于欠宜居一般协调状态。据此对城市群各市区人居环境的子系统进行空间分异,并提出实行城市管治模式、加强人居软环境建设,加快"两型"社会建设、构建和谐生态环境,加强城市规划和建设管理、完善引导和治理机制等优化人居环境的举措。

With the available data from RS, GIS and other various information sources, evaluates comprehensively the human settlement index and coordination degree of pan-Changsha-Zhuzhou-Xiangtan urban agglomeration by means of entropy method. The results show that： Changsha is the most livable and weak coordination; Zhuzhou, Xiangtan and Changde are secondary livable and weak coordination; Hengyang is secondary livable and narrow coordination; Yueyang is secondary livable and general coordination; Loudi and Yiyang are less livable and general coordination. On the basis of the results, analyzes the spatial differences of the sub-systems of the human settlement system, and brings forward the optimization measures about the human settlement environment： implementing urban governance model, strengthening soft settlement environment constructing, quickening two-oriented social construction, constructing harmonious eco- logical environment, enforcing urban planning and construction management as well as perfecting the urban guidance and administration mechanism.
