Qingshanzui Reservoir Engineering Administration, Chuxiong Yunnan 675000, China)  
For an example of area and its surroundings of Qingshanzui reservoir in Chuxiong as research area, on the basis of setting up a precise model after analyzing Landsat ETM+ remote sensing image in Sept. 2002 and Jul. 2004, combining different wave bank, and making the maximum likelihood to carry out supervising and classifying, a more precise classified result was obtained, analyzing the amount and spatial characteristic of it as well. At the same time, the effect and drawback of Land-satellite image with thirty-meter distinction which observing the ecological environment of surroundings of the reservoir was discussed in this paper.
