鲁豫黄河沿线县域经济发展和居住环境差异研究

Differences Analysis on Development of Economy and Habitat Environment in Counties along the Yello River in Henan and Shandong Province

县级行政区人口占全国人口比重大约70%,改善县城人居环境对于加快中国城镇化进程,提高城市化水平具有重要作用。通过选择具有代表性的人居环境指标,采用主成分和聚类分析方法对鲁豫黄河沿线的12个县域进行了综合评价,分析了各县人居环境现状差异。通过量化比较和综合分析,发现研究区域发展不均衡性明显。主成分分析表明,前三个主成分分别代表人口、经济和财政情况,是影响居住环境的关键因素。通过聚类分析把县城发展程度分为三类。结合实地考察的成果,分析区域差异存在的原因,提出一些改善现状的建议。

The population of county - level administrative region is about 70% percent of China＇s total population. The improvement of the habitat environmental in counties plays a crucial role in the course of promoting the process of urbanization and advancing the urbanization level in China. By selecting representative habitat environmental indicators, the present research uses principal component analysis and cluster analysis to evaluate the 12 counties along the Yellow River in Henan and Shandong province. And it is analyzed that the differences of county human settlements. Through comparative quantification and comprehensive analysis, it could find that uneven regional development is obvious. The principal component analysis proves that the first three principal components present the demographic, economic and financial situation. They are key factors which affected habitat envi- ronment. Then through cluster analysis, three development types are found. Combining the results of field investigations, this paper analyzes the reasons for the existence of regional differences and puts forward some recommendations to improve the situation.
