环太湖河流进出湖水量及污染负荷(2000-2002年)

摘要:
通过对环太湖水文巡测资料水量统计方法比较入手,计算分析2000-2002年环太湖河流进出湖水量、水质、污染负荷量变化.结合太湖水质变化分析,得出自2000年后环太湖进出湖河流的水质污染恶化趋势总体得到初步遏制,湖州、苏州地区环太湖河流水质保持稳定并呈一定改善趋势,但无锡、常州地区的环太湖河流水质浓度仍呈升高趋势,尤其是常州地区入湖河流的TP、CODMn浓度升高较快.与此相对应,太湖水质在总体保持基本稳定中有所好转,水质总体恶化趋势已经得到初步控制,但位于西北部的竺山湖各项水质指标进一步恶化,明显劣于梅梁湖水质,应当引起当地有关部门重视,加大治理力度.环太湖河流的入湖和出湖污染负荷量总体呈现增加趋势,但从净入湖污染负荷量分析,CODMn呈波动性减少趋势,TP和TN呈增加趋势.

Abstract:
Based on the statistics data about water quantity and wulrr quality of rivers around Lake Taihu,comparing with the water quality of Lake Taihu and the calculation result ol uiisie loads of rivers around Lake Taihu, the authors get the conclusion as follows: the degrading trend of water qiialilv of the rivers has been alleviated, the water quality of Lake Taihu has been improved step by step from 2000 to 2002. However,the water quality of the rivers from Wuxi and Changzhou area is being deteriorated. The East Lake Taihu holds the best water quality in contrast with the worst water quality of Zhushan bay in the northwestern Lake Taihu. The waste loads of rivers around Lake Taihu have increased from 2000 to 2002. But for the net waste loads of rivers around Lake Taihu, different water quality index has different trend. The waste load of CODMn decreased but the TP and TN increased.
Key words:  Rivers around Lake Taihu  water quantity  water quality  waste load
