摘要
通过获得的遥感数据资料,运用地理信息系统的空间分析和数理统计功能以及景观分析软件Fragstats分析了鄱阳湖区1985—2005年的土地利用变化特征及各种土地利用类型之间的转化情况和景观指标变化特点。结果表明:(1)鄱阳湖区在1985—2005年土地利用变化的特点是:耕地与水域的变化情况完全相反;其次是建设用地持续增加,而其他土地利用类型的变化幅度不大;(2)从整体上来看,耕地与水域之间实现转换,而建设用地的增加主要来自于耕地;同时,鄱阳湖区的土地利用变化在空间上存在着很大的差异性;(3)从景观格局指数的变化来看.鄱阳湖区的景观异质性程度在逐渐提高,土地利用向着多样化和均衡化的方向发展。
The characteristics of land-use changes of Poyang Lake Region among 1985-2005,the various types of land-use conversion,and the changes features of landscape indicator were analyzed by using of remote sensing database,GIS spatial analysis database, mathematical statistics and software named FRAGSTATS. The results show：（1） The characteristics of land-use changes of Poyang Lake Region among 1985-2005 are the changes in cultivated land and waters are exactly opposite,the built-up sites are increasing,the other types of land-use changes was not clear. （2） As a whole,cultivated land and water area achieved conversion, and cultivated land was transformed into built-up land. At the same time, there was obvious spatial difference of land use and land change in Poyang Lake. （3） From the change of landscape pattern index,we can see the landscape heterogeneity increased step by step,and land use developed towards diversity and evenness.
