摘要
根据 1 998年 1 1月和 1 999年 1 0月的监测数据 ,对零点行动前后太湖各监测点位的水质状况及DO、CODMn、TP、TN、Chla等主要指标的空间分布进行了对比 ,发现污染状况并未得到明显改善 ,除了人为因素外 ,非点源污染的贡献和底泥营养物质的释放是影响水质改善的
Based on field observations in November 1998 and October 1999,comparisons were made between them in quality and spatial distribution of principal pollutants(such as DO,COD Mn ,TP,TN and Chla)in the waters at various sampling sites. It is revealed that there is no significant improvement in water quality after the emission control. Non?point source pollution and release of nutrients from the sediment are probably the two major causes of the hysteresis.
