为补充中国海湾环境质量状况评估方法，作者通过整理和综合胶州湾常规监测项目中6年(2003~2008)的监测数据，经数据整理与综合、生境区域划分、评价因子选择、因子阈值确定、指数建立、指数验证与应用6个过程，初步建立了胶州湾浮游动物生物完整性指数(指数存在季节性差异，本实验以夏秋季节为例)。指数建立过程中将生境区域通过溶解性无机氮(DIN)、磷酸盐(PO4)及透明度3项指标划分为参照区和受损区，低营养盐、高透明度海域划为参照区，相反则划为受损区。通过检验11项浮游动物因子参照区与受损区的差异性，最终确定7项为指数建立的评价因子。对7项评价因子得分加权平均即得胶州湾浮游动物生物完整性指数得分。将指数得分划分为5个等级，分别表征不同的浮游动物要素质量状况。胶州湾浮游动物生物完整性指数的建立为从浮游动物角度评估胶州湾环境质量提供了新的方法，是对胶州湾生态环境质量综合评价的良好补充，能够更全面地反映海区浮游动物的质量状况，同时为发展和完善海湾生态系统质量综合评价体系奠定良好基础。

For replenishing method of evaluating the environmental quality of the Gulf of China, an initial Zoo-plankton Index of Biotic Integrity (Z-IBI) was developed from data of the Jiaozhou Bay Water Quality Monitoring Program monthly collected during 2003–2008. Dissolved inorganic nitrogen (DIN), orthophosphate (PO4), and Secchi depth were used to characterize zooplankton habitat conditions. Low DIN and PO4 concentrations and high Secchi depths characterized least-impaired conditions. Eleven zooplankton metrics were tested for their abilities to discriminate between impaired and least-impaired habitat conditions. Seven discriminatory metrics were chosen, and different combinations of these seven metrics were scored and used to create zooplankton community indexes for Jiaozhou Bay. The establishment of Z-IBI of Jiaozhou Bay provides a new method for evaluating environment quality from the perspective of zooplankton, which helps to develop and establish the comprehensive evaluation system of coastal ecosystem.
