以毕节石灰岩地区为研究对象,采用1992、2000、2036年的遥感影像和1:5万地形图提取不同年份的土地利用信息.在宏观方面以土地利用类型面积变化率方法揭示了不同时期各类型面积变化状况,数据显示各类型变化率逐渐减少,说明土地利用结构趋于稳定;在缀观方面以土地利用动态变化和内部转移矩阵表现土地利用变化程度和方向,各类型动态变化的比例整体上趋于减少,说明土地利用类型内部流转性降低,整体上趋于平衡.
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.
