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.
