摘　　要：针对漓江流域自然地貌被人为破坏的现状,以0.61 m分辨率的QuickBird 2和5.6 m分辨率的IRS-P6卫星遥感数据为信息源,在ENVI和MapGIS软件的支持下,对漓江流经桂林市区段,即兰洲大桥—磨盘山大桥之间约30 km河岸自然地貌遭受人为破坏的现状开展了遥感调查。通过遥感图像处理、分析和人机交互解译,对3种河岸地类(农林用地、建筑用地和自然景观区用地)进行了测量与统计分析,结果表明:2009年漓江两岸农林用地占岸长度为河岸总长度的57.78%,建筑用地占35.95%,自然景观用地仅占6.27%。这说明,随着桂林城市规模的急速扩展,人类活动对漓江自然地貌形态造成了严重破坏,漓江综合治理已经刻不容缓。In view of the increasing man - made damage situation, the authors employed the high resolution satellite QuickBird -2 （resolution 0.61 meters） and IRS -P6 （resolution 5.6 meters）remote sensing data and utilized ENVI and MAPGIS software to conduct remote sensing investigation of the part of Guilin city through which the Lijiang River is flowing, and the survey area covered both banks of the Lijiang River between Lanzhou Bridge and Mopanshan Bridge about 30 km in length. Through remote sensing image processing, analysis and human - machine interactive interpretation, the authors made measurement and statistical analysis of three kinds of man - made damage. The results show that until 2009, the natural landscape area had accounted for 6.27% of the whole investigated area, agriculture and forestry land accounted for 57.78% and land for construction accounted for 35.95%. These data suggest that, with the rapid expansion of the Guilin city, Human activities caused serious damage to the Lijiang River＇ s natural landscape, and hence the comprehensive treatment and harnessing of the Lijiang River are urgent.
