行政区划调整对土地利用空间特征演变的影响--以广州市南沙地区为例

Impacts of Administrative Division Adjustment on Spatial Characteristics of Land Utilization:A Case Study of Nansha District in Guangzhou

行政区划调整是推动地方发展与重构空间权力的重要策略,但现有研究缺乏对行政区划调整的影响机制的关注。文章以土地利用为研究对象,选取广州市南沙地区为研究区域,梳理其自1992年以来行政区划调整的历程,利用ArcGIS空间分析软件对其土地利用空间特征的演变进行分析,探讨行政区划调整对土地利用空间特征的影响过程与机制。结果表明,行政区划调整通过行政资源在空间上的布局直接与间接影响土地利用的空间特征。其中,直接影响通过政区类型、隶属关系、等级权限、组织体制等行政资源与体制在空间的布局调整而产生影响;间接影响是行政区划通过对城市发展动力、经济发展模式、其他空间政策、行政主体以及市场主体等其他因素而对土地利用空间特征产生影响。

The Administrative Division is a crucial strategy for government to promote local development and reconstruction of spatial power. However, currently the studies about the mechanism of the administrative division are still very few. This paper was selected Nansha District in Guangzhou as a case to review the administrative division history since 1992 by focusing on its land use allocation changes. By using Arc GIS to analyze the evolution of spatial characteristics of land use allocation, the impacts brought by the administrative division on the spatial characteristics of land use were explored. It is indicated in this paper that the administrative division has both direct and indirect impacts on land use allocation based on the spatial layout of administrative resources including the types of administrative zones, the relationship between administrative subordinations, the grade of both administrative system and its authority and administrative range, and the location of government. Furthermore, this paper also analyzes the emergence mechanism of the direct and indirect impacts. It is shown that administrative division has direct impact on land use spatial allocation through change of allocation of administrative resource such as administrative region type, administrative subordination, privilage level and organization system, while indirect impact through urban development power and mode, other spatial policy, administrative subject and market power.
