Spatio-temporal Changes of Land-use in Hefei during Past 19 Years
In the past 19 years,while China's urbanization was fast-developing,a series of problems related to urbanization were there upon production.In this paper,based on spectrum characteristic of knowledge method,the thematic information of three periods of LUCC were extracted from Landsat TM,ETM + and CBERS-2.Combing with the GIS technology,the land-use transfer matrix from 1987 to 2006 were obtained.Besides,the LUCC models were applied to analyze the characteristic of land use change from 1987 to 2006.Based on the land-use change map and land-use transfer matrix,spatial dynamic characteristic and land-use conversion of the study area were analyzed.The research could provide suggestions for land management and making policy for local government.
