Abstract
宜溧河流域是太湖的主要集水流域,流域水体的水质状况及营养状态与太湖的水质状况与营养状态密切相关.本研究根据2000年12月14-15日以及2001年4月18-19日两次大规模的水质同步监测结果,对流域平原河网地区水体的水质状况及营养状态进行了系统综合的评价.评价结果表明:不管是平水期还是枯水期,河网水体的水质状况都较差,营养水平较高;在枯水期间,受多种因素的综合影响,水体的水质状况呈现恶化趋势,营养盐含量也有所升高;The Yilihe watershed is the main water catching area of the Taihu Lake. The conditions of water quality and nutrition of water bodies of the watershed closely relates to that of the Taihu Lake. Based on the large-scale synchronous environmental monitoring of December 14-15 of 2000 and April 18-19 of 2001 we give systematically assessment of the conditions of water quailty and nutrition to water bodies of the plain river network area. The results indicate that, water bodies have bad quality and high nutiite either in normal period or in drought period but, in drought period,water quality became worse and water bodies have even higher nutrite contents.
