京津冀城市群发展的时空演变特征初探

A PRELIMINARY STUDY ON THE SPATIAL AND TEMPORAL EVOLUTION OF URBAN AGGLOMERATION IN BEIJING-TIANJIN-HEBEI REGION

近年来京津冀城镇体系得到了高速发展,但也出现了经济社会发展与环境生态可持续发展不协调、区域发展水平严重不平衡及空间差异大等问题。本文基于城市地理学视角,从城市发展水平和城市规模体系两个层面,运用了主成分分析、城市首位度、基尼系数及Moran's I指数等方法和指标,结合GIS技术制作专题地图进行分析,初步探究了京津冀地区城市群发展的时空规律,并结合实际情况为促进京津冀协同发展提出一些建议。

In recent years, the urban system of Beijing-Tianjin-Hebei has been developing rapidly. However, many issues have arisen, such as the conflict between the ecological and environmental sustainability and the development of society and economy, and the seriously imbalanced development level of different spatial regions. Based on the perspective of Urban Geography, this paper conducted a research from two aspects-city development level and city scale system, using principal component analysis, law of the primate city, Gini coefficient, Moran's I index and some other methods, combining spatial analysis with thematic maps made in Arc GIS. This paper explored the law of Beijing-Tianjin-Hebei urban agglomeration's spatial and temporal development and put forward some practical suggestions and concepts to promote further coordinated development of Beijing-Tianjin-Hebei Region.
