摘　　要：根据2009—2011年莱州湾渔业水域的环境监测调查数据,按照中国相关的环境质量标准,利用单因子污染指数、有机污染指数和生物多样性指数来评价水环境质量。结果表明,利用单因子污染指数法、有机污染指数法评价显示莱州湾调查水域的水环境质量稳定性较差;其中2009年和2011年评价结果为严重污染,2010年为较清洁;水体污染主要体现在氮和磷的超标。同时,利用生物多样性指数进行评价的结果与实际环境状况不一致,即调查水域为严重污染时,多样性指数依旧较高。建议利用生物多样性指数开展环境质量评价时,应结合其他指标进行综合评价。[中国渔业质量与标准,2014,4(6):50-58]Based on the environmental monitoring data in fisheries area of Laizhou Bay in 2009-2011, the water environment quality was assessed according to the relevant environmental quality standards of China by using single factor pollution index, organic pollution index and biodiversity index. The results showed that the water environment quality status of the survey area was unstable by the methods of single factor pollution index and organic pollution index. Thereinto, the survey area was heavy pollution in 2009 and 2011, but clear in 2010. The main pollution indicators were nitrogen and phosphorus. Meanwhile, the assessment result by biodiversity index method was inconsistent with the actual environmental conditions. In other words, the diversity index was still high when the water environment was heavily polluted. Consequently, when the water environmental quality isevaluated by using biodiversity index, it should be suggested to carry out comprehensive consideration combined with other indexes.
