基于AHP与GIS的城市可持续性测度与空间比较研究——以东北地区35市(州)为例

Study on the Spatial Comparison and Measurement of Urban Sustainability Based on AHP & GIS Approach——A Case of 35 Municipalities in Northeast China

以东北地区35市(州)为案例,根据数据源条件,从经济、社会、生态3个子系统构建了包含12项指标在内的城市可持续性空间测度评价指标体系,基于可持续发展指标校正模型,采用AHP分别计算了东北三省35市(州)经济、社会、生态子系统的发展指数及综合发展度与协调度,通过可持续性空间测度与比较,阐析了东北地区35市(州)在可持续发展上的空间关联特征及其基本规律。研究结果表明:城市可持续性具有地理空间差异与地域分异规律,以沈阳为代表的转型成功的老工业区和以大连为代表的现代新型城市可持续发展度较高,而边远地区及处于转型中的老工业城市则相对较低;中心城市的辐射作用明显,对其周边城市的可持续性影响较大;经济、社会、生态子系统之间存在着较为紧密的耦合与转换关系,因此,在制定城市可持续发展政策中必须因地制宜,并且要从城市群或经济区等视角推进城市可持续发展。

By taking the 35 municipalities in Northeast China as studied cases, an principles-oriented index system was firstly proposed which contained 12 indicators categorized as 3 subsystems named as economic , social- and ecological-subsystem, and then the developmental indices were calculated by employing the modi- fied sustainability assessment model and analytic hierarchy process method, followed by index＇ visual and ex- ploring analysis, finally the spatial relationship and basic phenomenon into municipal scale sustainability measurement were concluded. The results showed that the successful transited industrial and new-emerging cities such as Shenyang and Dalian had higher sustainability, while lower sustainability was found in the out- land and transiting cities, the effectiveness of the central city was significance which meant they had obvious influences on its satellite and surrounding cities, coupling and dual-shifting relationship existed among eco- nomic-, social- and ecological-subsystem. It is suggested that policies towards for sustainable development must closely combine with the local conditions and made appropriate methods in respect of macro level such as urban clusters and economic zone.
