摘　　要：海水养殖是河北省水产业重要的支柱产业。为了保护河北省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年的监测数据,采用模糊综合评价法和单因子污染指数法对海水养殖区水质的时空变化特征和质量状况进行了研究与评价。结果表明:近年来河北省海水养殖区水质逐步有所好转,其中秦皇岛市、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,黄骅市附近海水养殖区的水质污染较重,已不能满足养殖用水的要求;河北省海水养殖区水体中主要污染物是磷酸盐(PO34--P)、无机氮(DIN),其次为铅(Pb)和汞(Hg)。Mariculture is an important pillar industry of aquaculture in Hebei Province.The spatial-temporal variations in the seawater quality in mariculture area of Hebei Province were studied by the monitoring data from 2000 to 2010 and the seawater quality was evaluated by the fuzzy synthetic evaluation method and the single factor pollution index method in order to preserve the ecological environment of mariculture area and ensure the sustaining development of the mariculture.The results showed that the seawater quality in the mariculture area in Hebei Prvince was shown better in recent years.The seawater quality of mariculture area in Qinhuangdao and Tangshan met the requirements of aquaculture water,but the seawater quality in Huanghua was polluted seriously and did not meet the requirements of aquaculture water.The major pollutants in seawater in Hebei Province mariculture area were PO3-4-P and DIN,followed by Pb and Hg.
