摘　　要：利用徐州市主城区1990～2005年间四期Landsat TM遥感数据及其它相关非遥感数据,通过处理获取主城区景观空间结构信息和景观格局的各种指数、景观类型转移矩阵和景观演变动态度来定量测评主城区的景观结构在时间维和空间维上的演变。研究结果表明,徐州主城区景观类型格局发生了很大改变。建设用地呈逐步增加的趋势;而以耕地面积呈逐步下降的态势;林地、水体和未利用地变化呈起伏状态,幅度较小,总体上没有太大变化;徐州市主城区景观破碎度增大、优势度指数降低、整体分维数略有增加,城市景观格局趋于复杂化、破碎化和多元化。Making use of four scene Landsat TM remotely sensed images and other related non-remotely sensed data as data source,the main city zone landscape spatial structure information,and calculated various factors of landscape pattern,landscape transfer matrix.can be obtained quickly and precisely.The results shows that the main city landscape has undergone huge changes between 1990-2005.The percentage of building land had being increased gradually;while the percentage of farmland had being rapidly decreasing,and illustrate a trend of rapid decreasing.The area of woodland,water and unused land had almost no change,In the research area,landscape fragmentation increased,the dominance index decreased,fractal dimension has a slight increase,and the urban landscape pattern tend to more complication,fragmentation and diversification.
