With the aid of the spatial analyzing technology, three periods land use data of the Longchuanjiang catchments have been obtained. Raster-conversion and cartographic algebraic operation were conducted of the land coverage data, using a complex method integrating GIS spatial analysis with traditional statistical analysis, to create a new GRID database. Based on the database, the effect of land use...
This study presented an economic model for estimating the land use structure changes based on Landsat Thematic Mapper (TM) imagery. The Lorenz Curve and Gini coefficient, derived from Economics, were introduced as tools for investigating and quantifying the land use structure changes from 1987 to 2007 in Xiamen, China. The results showed that the spatial Lorenz curve had the phenomenon of “three near...
