摘　　要：【目的】研究水质质量综合评价模型的构建及应用。【方法】根据我国近海海洋环境监测指标和《国家海水水质标准》,运用PCA法,构建近海水质质量的综合评价模型,并给出四类水质综合指数F的量化区间值。【结果】在九龙江及毗邻海域,利用该评价模型开展示范应用研究,计算并绘制水质质量F值的空间分布和平面分布,筛查出污染的关键区域和指标,九龙江口水质质量综合指数F值区间为-1.875~2.570,以三类或四类为主。【结论】评价结果较好反映了九龙江口水质环境实际情况,水质质量综合评价模型可为该海域海洋环境综合治理及利用提供参考。【Objective】The construction and application of water quality comprehensive evaluation model were studied.【Method】Based on the inshore marine environmental monitoring indicators and the National Seawater Quality Standard, a comprehensive evaluation model of the coastal water quality was established by using the PCA method, and the quantitative interval values of four kinds of comprehensive index F were obtained.【Result】In Jiulong River and the adjacent sea areas, the model was used to carry out demonstration application research, and the spatial and horizontal distribution of F value of water quality was calculated and plotted.The key areas and indicators of pollution were screened out.The results showed that the F value range of water quality in Jiulong River Estuary was-1.875 ~ 2.570, and mainly divided into three or four categories.【Conclusion】The assessment results reflected the actual situation of the water quality and environment of the Jiulong River Estuary.Comprehensive assessment model for water quality could provide some reference for the comprehensive management and utilization of the marine environment in the sea area.
