基于遥感技术的太湖近15年面积动态变化

Dynamic Change of Lake Taihu Area During the Past 15 Years Based on Remote Sensing Technique

本文利用80年代后期以来不同时期的LANDSAT卫星遥感图像,研究了近15年太湖的面积变化状况。研究结果表明:从1988年到2003年的15年来,太湖面积共减少9.0226km2,其中湖泊围垦了4.4584km2,湖滩地面积0.6968km2,取土围堰面积3.8674km2.

Rased on the LANDSAT remote sensing images since the late 1980s, the area change of Lake Taihu in the recent 15 years was studied. The results showed that of 9.0226 km2 the lake area had collectively declined from 1988 to 2003, 4.4584, 0.6968 and 3. 8674 km2 of which were due to reclamation, bottomland and cofferdam respectively.
