摘　　要：利用南宁市2010年的Spot5及1990年的TM数据,结合遥感解译的方法,对比分析区内地表水体20年来的变化.过去20年来,研究区河流由7条变化为4条,总长度由79.51km缩短为71.04km,湖泊总面积由9.26km2减小至5.05km2,缩小了4.21km2,水库总面积由1.73km2减少至1.32km2,减少总面积0.41km2.With the development of the remote sensing interpretation,combining the re- mote sensing interpretation with the space-time evolution of water resources has been an important subject. The 2010＇s Spot5 image data and the 1990＇s TM image data of Nan- ning City were used to compare the surface water changes of the study area in the past 20 years. The result shows that, in the study area, the number of the river changed from 7 to 4, and the length shortened from 79.51 km to 71.04 kin. The total area of lakes changed from 9.26 km2 to 5.05 kmz , reducing 4.21 km2. The total area of reser- voir changed from 1.73 km2 to 1.32 km2, reducing 0.41 km2.
