摘要
基于Shannon信息熵理论,依据2005—2010年南京市土地变更调查资料,分析研究了南京市整体及市内各片区的土地利用结构信息熵动态演化。结果表明,南京市土地利用结构信息熵和均衡度近6 a呈现波动中趋向上升的状态;主城区与其他片区的土地利用结构均衡度的空间分异特征十分突出。揭示影响南京市土地利用结构信息熵和均衡度变化的驱动因素,对预测和规划今后一定时期内南京市以及同南京市具有类似区位条件和经济发展水平城市的土地资源开发利用保护、区域土地利用结构调整具有借鉴意义和指导意义。
Based on Shannon entropy theory, according to the survey data of land change in Nanjing from 2005 to 2010, the dynamic variation of information entropy of land use structure in the whole Nanjing and each area in the city are studied. The results are as follows： the information entropy and equilibrium degree are gradually rising with a trend of fluctuations in recent six years. The spatial differentiation characteristics are very prominent of equilibrium degree of land use structure in the urban and other area. Revealing the driving factors that is influencing the variation of information entropy and equilibrium degree of land use structure in Nanjing has the same significance not only for predicting and planning the development, utilization and protection of land resource, structure adjustment of regional land use of Nanjing, but also for those cities which face the similar geographic conditions and economic development level.
