政府行为视角下的珠江三角洲核心区空间形态演化分析

Analysis of Spatial Morphology Evolution in Core Area of Pearl River Delta from the Perspective of Government Behavior

自改革开放以来,珠江三角洲地区迅速崛起,其空间演变的特征及动力机制也成为研究的热点。本文利用RS与GIS技术方法,从整体角度展现和描绘了改革开放30年间珠江三角洲核心区城镇空间形态由点状扩张到线状空间,再到形成密集发展带和都市建设圈层的动态演变过程,并从政策变化、城市规划调控等政府行为的角度解释该区空间发展演变的机制,以期为区域协调发展决策与管理提供依据。

The Pearl River Delta develops quickly since the reform and opening-up, and the characteristics and dynamics of spatial evolution have also become the research focus. This article utilizes RS and GIS techniques and describes the dynamic evolutionary process of the urban spatial morphology in core areas of Pearl River Delta since the reform and opening-up30 year ago, which expands from spotted-shape space to linear- shape space, and finally shapes a dense development belt and urban construction ring layer. Furthermore, the article explains the evolution dynamics of spatial development in this area from the perspective of government behaviors such as policy change and urban planning, and it provides basis for regional coordination develooment decision and management.
