Analysis on Dyanmic Change of Land Use in Bijie Limestone Regions
Taking limestone regions in Bijie Prefecture as a rescearch object.the land use data of different year were obtained by interpreting the RS images in 1992,2000,2008 and 1:50000 landform map. By methods of aera change rate of 1and use types,macroscopical studies were mainly focused on revealing acreage change of the types in different period,and the data showed that the rates of types had reduced gradually,which indicated that the structure change of land use was tending towards stability. Microscopically. methods of dynamic changes of land use and internal transition matrix were used to reveal magniitude and direction of land use,the conclusion was that dynamic change proportion of each type tended to reduce, which explained that the internal circulation of land use types have decreased and tended to be balanced on the whole.
