摘　　要：采用1986～2006年潘家口水库水质监测资料，分析水质时空变化规律。结果表明水库水体高锰酸盐指数较早期没有增加，但存在一定的增加趋势，总氮和总磷较早期有显著增加，富营养化趋势明显。采用引滦入津工程沿程8个监测断面的监测资料，分析水质空间变化规律，发现潘家口水库上游污染严重，下游水质较好。从水文变化和人类活动两方面，分析水质演化原因，据此提出了引滦入津工程水资源保护建议。Using Panjiakou Reservoir water quality monitoring data from 1986 to 2006, the temporal variation of water quality was analyzed. The results show that, compared with the early data, the COD Mn. concentration showed no obvious rise but presented an increasing trend, and the concentrations of TN and TP increased greatly, causing eutrophication. The spatial variation of water quality was also analyzed using data from eight monitoring sections along the water diversion project from the Luanhe River to Tianjin City. The results show that the water upstream of the Panjiakou Reservoir was seriously polluted and the status of the downstream water quality was good. From human activities to hydrological changes, the reasons for water quality variation are discussed, and water resources protection measures are proposed.
