基于GIS的城镇发展适宜性与区域经济发展情况的耦合关系——以武汉市黄陂区为例

Coupling Relationship between Urban Development Suitability and Regional Economic Development Condition Based on GIS Taking Huangpi District of Wuhan City as an Example

为了研究城市发展适宜性与经济发展水平的关系,以湖北省黄陂区为例,从自然适宜度、区位适宜度、生态适宜度和土地转换适宜度4个方面共10个因子层构建了综合评价指标体系。应用GIS技术,通过采用层次分析法(AHP)与专家打分法综合确定因子指标权重与量化标准,评价了研究区的城市建设用地生态适宜性,从经济发展水平的角度分析了城镇发展适宜性与区域经济发展情况的耦合关系。结果表明:区域经济发展水平与区域内各级城镇发展适宜性用地的占比紧密相关,适宜城镇发展的用地占比越大,其经济发展水平越高。

In order to study the relationship between urban development and appropriateness of economic development level, taking Hubei Huangpi district for example, from natural suitability, location suitability, ecological suitability, and land conver- sion suitability four aspects of a total of 10 layers to build a comprehensive factor evaluation system. Based on GIS technology, Analytic Hierarchy Process （AHP） and expert scoring method were integrated to determine index weight factor weight and quan- titative criteria to evaluate the urban land ecological suitability of the study area. Coupling relationship between urban develop- ment suitability and regional economic development was analyzed from economic development level. Results showed that, level of regional economic development was closely related to proportion of suitability land at all levels of urban area in the region. Level of economic development was higher as land use ratio which was suitable for development of towns was greater.
