【摘要】 太湖的生态环境一直倍受关注。本文采用遥感方法,结合实地考察和文献资料,利用GIS技术,对太湖1988~2003年期间的围湖利用面积和东太湖1990~2003年期间网围养殖面积的动态变化进行了研究。结果表明,1988~2003年期间,太湖围湖利用面积8.3258km2;1990~2003年期间,东太湖网围养殖的面积增加94.0129km2,2003年网围养殖面积达106.4702km2,已占东太湖水面面积79.3%。对大规模围湖利用和过度网围养殖引起的环境效应进行了分析,并且针对当前太湖资源开发利用存在的问题,提出了若干对策与建议。更多还原

【Abstract】 The ecological environment of Lake Taihu has attracted widespread attention in recent years.Combining field survey and data from the literature,the dynamic changes of land reclamation from 1998 to 2003 in Lake Taihu and enclosure aquaculture from 1990 to 2003 in Lake East Taihu were studied by remote sensing and GIS techniques,and the environmental effects of large-scale land reclamation and excessive enclosure aquaculture in Lake Taihu were analyzed.The results showed that the area of land reclamation was 8.3258 km² in Lake Taihu from 1988 to 2003 and the area of enclosure aquaculture increased 94.0129km² in Lake East Taihu from 1990 to 2003,and reached106.2702 km²,accounting for 79.3% of the total area of Lake East Taihu in 2003.Based on the analyse of the situation and problems of the ecological environment,some countermeasures are suggested for the exploitation of the lake.更多还原
