摘　　要： 以福州和台北的ASTER和TM遥感影像为数据源，提取两市中心城区绿地信息并计算景观生态指标。对比分析结果表明：1988-2004年期间，两市中心城区面积增加，绿地面积及其所占比例减少，但福州城镇扩张速度和绿地面积所占比例下降幅度远大于台北；两市绿地斑块形状趋向简化，连通性变小，聚集程度降低；与2004年福州相比，2003年台北中心城区绿地的形状更规则，连通性更强，聚集程度较高。 With Fuzhou and Taipei serving as study regions, comparative analysis serving as study method, ASTER and TM serving as data sources, the study extracted green land information and calculated landscape indexes of urban cores in Fuzhou and Taipei. The results showed that： both areas of urban cores, green lands and their area percentages increased while there was an increase in land use of town and a decrease of green land area percentage in Fuzhou; and the change tends are almost the same in patch shape, connectivity and aggregation in the two regions while there was simpler patch shape, higher connectivity and aggregation in Fuzhou in 2004 than those in Taipei in 2003.
