摘　　要：利用经纬度网格法,采集不同汛期巢湖水体样品,根据水化学分析实验结果研究巢湖水体氮磷营养盐浓度及其时空分布特性。结果表明,巢湖入湖河流中,受秋冬季接纳生活污水、工业废水的影响,南淝河、十五里河TN浓度超标严重,TP浓度次之。巢湖整体呈现西部湖区氮磷营养盐浓度高于东部湖区的趋势,巢湖污染状况依然严重。In order to research the concentrations,spatial and temporal distributions of nitrogen and phosphorus nutrients in Chaohu Lake,the surface water samples in different flood seasons are collect-ed by grid sampling methods.The results show that the concentrations of TN,TP in Nanfei River and Shiwuli River are higher than other rivers because of domestic sewage and industrial sewage.The con-centrations of N and P nutrients in the western part of Chaohu Lake are higher than those in the east-ern part.The pollution in Chaohu Lake is still serious.
