基于熵权TOPSIS模型的南方丘陵地区乡村人居环境评价——以赣州为例

Evaluation of Rural Human Settlement in Hill Area in Southern China Based on Entropy TOPSIS Model——A Case Study of Ganzhou

以赣州18个县(市)为研究对象,构建由目标层、系统层和指标层组成的乡村人居环境评价体系,运用熵权TOPSIS模型对南方丘陵地区的乡村人居环境质量进行评价,并运用Arc GIS9.3对2013年赣州市乡村人居环境空间分异进行可视化与特征分析。结果表明:(1)在5项一级指标中,社会文化环境所占权重最大,经济指标权重最小,说明在乡村人居环境评价指标体系中,社会文化是一项重要指标,经济是基础指标;(2)赣州乡村人居环境呈现"单核突出,整体跟进,局部沦陷"的空间格局;(3)表征人居环境质量的各项指标在空间上显示出集中程度不同的空间分异特点。通过对案例区人居环境空间特征形成机制的分析,以期为赣州乡村人居环境建设提供参考和建议,并尝试为南方丘陵区同类型乡村人居环境规划与建设提供理论支持与科学依据,促进该区域乡村人居环境协调发展。

Taken 18 counties in Ganzhou as case study,the quality of rural human settlements in hills in southern China was evaluated in this paper. An evaluation system was developed for rural human settlements incorporating a target layer,system layer,and index layer,the entropy TOPSIS model was used to evaluate the quality of rural human settlements,and Arc GIS was used to analyze its spatial differentiation from the perspective of visualization.The results showed as the follows ：（ 1） the social and cultural environmental index made up the largest contribution of any of the 5 first-level indicators,and kept the economic index the smallest,which suggested that a system designed to evaluate rural human settlements should consider social and cultural environment an important indicator and economy a basic indicator;（ 2） Ganzhous rural human settlements presented the spatial pattern ＂single core structure,the overall follow-up,some parts fall behind＂; and（ 3） the indicators of rural human settlements showed different spatial concentrations in different indicators. Through analysis of the mechanism underlying the formation of human settlements space characteristics,these results were expected to provide references and suggestions for the construction of rural settlements in Ganzhou. This work was designed to promote and provide theoretical support and scientific basis for the regional coordinated development of rural human settlements of the same type in southern Chinas hills.
