利用多期LandsatTM、LandsatETM+和航片从时间、空间和利用类型3个方面分析了太湖围湖利用、网围养殖的时空变化。结果表明:1984—2003年间太湖围湖利用面积为4.45km2,与20世纪50年代至70年代中期相比,围湖利用规模较小、速度较慢,围湖利用的主要类型是鱼塘养殖,主要分布在苏州市;太湖网围养殖增长迅速,尤其是1995年以后,1990年太湖网围养殖面积13.17km2,1995年为25.95km2,2003年为107.72km2,1995—2003年间网围养殖年增长速率是1990—1995年间年增长速率的4倍,太湖网围养殖主要分布在东太湖。
The temporal and spatial variations of the utilization and net culture of Lake Wai in Taihu Lake were analyzed from three aspects of time, space and utilization types using multi-period LandsatTM, Landsat ETM + and aerial photographs. The results show that the use area of Lake Taihu Lake was 4.45km2 between 1984 and 2003. Compared with the mid-1950s to the mid-1970s, the use of Lake Wai was relatively small and slow. The main types of lake utilization were fish ponds, Mainly distributed in Suzhou City; Taihu Wai around the rapid growth of aquaculture, especially after 1995, Taihu Lake in 1999 around the aquaculture area of 13.17km2, 25.95km2 in 1995, 107.72km3 in 2003, The rate was 4 times of the annual growth rate from 1990 to 1995. Taihu Wai Wai mainly distributed in the East Taihu Lake.
