摘　　要：海水养殖是河北省水产业的支柱,为了保护海水养殖区的生态环境,实现海水养殖业可持续发展,根据2000-2010年监测数据,分析海水养殖区水质的时空变化特征,采用模糊综合评价法和单因子污染指数法对水质进行评价。结果表明,近年来河北省海水养殖区水质逐步好转,其中秦皇岛市和唐山市附近海水养殖区水质基本可以满足养殖用水的要求,黄骅附近海水养殖区水质污染较重,已不能满足养殖用水的要求。水体中主要污染物是磷酸盐(PO3-4-P)和无机氮(DIN),其次为铅(Pb)和汞(Hg)。Maricuhure is an important pillar industry of aquaculture in Hebei Province. In order to preserve the ec- ological environment of mariculture area and ensure the sustainable development of the mariculture, with the fuzzy synthetic evaluation method and the single factor pollution index method, the study on space-time variation charac- teristics and assessment of the seawater quality were carried out in mariculture area of Hebei Province according to the monitoring data from 2000 to 2010. The results showed that in recent years, the seawater quality of maricuhure area in Hebei Province has been becoming better. The seawater quality of maricuhure area in Qinhuangdao and Tangshan could meet the requirements of aquaculture water, but the seawater in Huanghua was polluted seriously and could not meet the requirements of aquaculture water. The major pollutants in seawater in Hebei Provincial mariculture area were phosphate （PO4^3--P） , and inorganic nitrogen （DIN） , followed by Pb and Hg.
