摘　　要：2004年5月和8月对河北海域进行了两次调查,布设了16个段面70多个站位。对该海域水质进行了无机氮、无机磷、COD、DO等项监测。本文对两次调查结果进行了分析和评价,结果表明,河北海域无机氮和无机磷的含量由北向南逐渐升高,接近天津海域含量达到最高。8月份监测结果普遍高于5月份,断面调查结果均显示营养盐主要来自于陆源。采用有机污染指数和富营养化指数计算结果表明,M断面5月份开始受到污染,8月份受到严重污染,富营养化程度5月份L、M断面E>1,其他各断面E<1,8月份K、L、M、N、O、P断面E>1,其他各断面E<1。Based on the investigation in May and Aug. ust of 2004 in Hebei coastal sea, which was selected, the sampels of 16 profiles and 70 monitoring sites were selected, and DIN, DIP, COD and DO were monitoreddetermined. The monitoring data was analyzed and assessed in this paper. The monitoring data showed that the concentration of DIN and DIP increased gradually from north to south, and it reached the highest concentration in the area around Tianjin. The monitoring data inof Aug. ust was higher than that ofin May, and it also showed that nutrients in the of coast mainly came from the land scours. The calculating results of the organic pollution index and eutrophication index showed that M profiles was polluted in May, and was polluted severely in Aug. ust, the degree of eutrophication of the L, M profiles was E 〉 1 and others was E 〈 1 in May, and the degree of eutrophication of the K, L,M,N,O,P profiles was E〉 1 and others was E〈 1 in Aug.ust.
