ANALYSIS ON INFORMATION ENTROPY OF LAND USE STRUCTURE IN CHANGSHA CITY
基于1996-2007年长沙土地利用数据，用信息熵、均衡度和优势度分析其结构动态变化，发现熵值持续上升、用地趋于均衡，对城市规划者优化用地有参考价值。
Research on urban land utilization,analyzing the status and the existing main problems of urban land utilization in a quantitative way to come up with strategies to increase the efficiency of urban land utilization,will be helpful to further understanding the reason and mechanism of the change of land utilization.Also,it will make land use more reasonable and sustainable.On the basis of the data of land utilization in Changsha city from 1996 to 2007,integrating with the principle of information theory,including information entropy,equilibrium degree and dominance degree,this paper has analyzed the dynamic evolution characteristics of land utilization structure in Changsha city.It was revealed that the information entropy of land utilization in Changsha city continues to rise,and equilibrium degree and dominance degree are in the state of fluctuation.Meanwhile,land utilization functions relatively expand and the types of land space utilization tend to be equilibrium.
