Abstract:

The research on temporal and spatial distribution characteristics of land use is one of important research aspects of temporal and spatial process in land change science.It is of great significance for comprehending region land resource situation and making differential competition policy of regional development.Based on the land use classification statistics,the temporal and spatial distribution characteristics of land use were studied from a macro perspective of geospatial statistics by using the Theil Index.The analysis showed that the Theil Index of land use distribution was sensitive to research granularity.The larger particle size of study would ignore the detail characteristics of the spatial distribution of land use,resulting in the smaller value of Theil Index .Through the geospatial regionalization and decomposition of Theil Index,not only the temporal and spatial distribution characteristics of land use were studied on the overall aspect,but also the difference of temporal and spatial distribution of land use between and inner partitions were researched according to the different levels of economic and social development.The result revealed the temporal and spatial distribution characteristics of land use in Changzhou city from the aspect of spatial concentration,which was coincide with the actual situation
