武汉城市圈土地利用结构演变规律及驱动因素分析

Study on Laws and Driving Factors about Evolution of Land Use Structure in Wuhan Metropolitan Area

采用武汉城市圈1997-2006年土地利用变更数据,计算各城市及武汉城市圈整体的信息熵、均衡度,并进行对比分析,以揭示武汉城市圈土地利用结构演变的规律和驱动因素。研究结论:①武汉城市圈土地利用结构均质性较差,但趋向于合理方向发展;②影响武汉城市圈土地利用结构演变的驱动因素众多,其中土地内在的特性和规律及政策、产业结构、区位可达性等外部因素尤为重要。

This paper calculates the information entropy and equilibrium degree by using the change datas of land use in Wuhan metropolitan area from 1997 to 2006, analyzes the similar and different features, and reveals the laws and driving factors about the evolution of land use structure in Wuhan metropolitan area. The conclusion of the study is that the homogeneity of land use is poor in Wuhan metropolitan area, but it is developing in a reasonable direction.Many factors affect the evolution of land use structure in Wuhan metropolitan area, the inherent characteristics of the land, policies, industrial structure and location accessibility are particularly important external factors.
