摘要
以1997年的TM和2007年的ASTER遥感影像数据的为主要数据源,利用遥感和地理信息系统技术,对影像进行监督分类获得土地利用变化的数据,并计算出研究区的土地利用类型的动态转移矩阵、LUCC幅度、动态度和状态指数等指数模型,定量分析研究区的土地利用变化情况。结果表明:1997-2007年间,耕地和草地大量减少,其他土地都在增加,园地变化幅度最大,其次是林地;主要土地利用转移类型:草地转化为林地和耕地,耕地转化为林地、草地和园地,LUCC处于不平衡状态。
Based on remote sensing imagery data of 1997 and 2007,using the technology method of Remote Sensing(RS) and Geography Information System(GIS),land use change data was obtained by applying the method of supervised classification.According to land use change data,dynamical transition matrix,the amplitude of land use change,dynamical degree and state index of land use were calculated to study and analyze quantitatively land use change.Results were showed out: between 1997 and 2007 year,both farm land and grass decreased largely,the rest increased;the amplitude of garden plot was the largest,and the amplitude of forest was the second;the main transition types: grass transferred to forest and farm land,farm land transferred to forest,grass and garden,LUCC was in a state of unbalance.
