| 摘 要： | 根据2002～2003年5、8月对我国沿海的莱州湾、长江口和珠江口渔业水域的水质、沉积物、浮游生物的监测结果，采用主成分分析法，综合评价这3个重要渔业水域的生态环境质量状况。研究结果显示，莱州湾水域生态环境综合质量相对较好，处于“一般”状态，但随时间变化生态环境质量正朝不良方向发展；珠江口水域生态环境综合质量次之，也处于“一般”状态；长江口水域生态环境综合质量最差，处于“差”状态，生态环境质量状况夏季劣于春季。从3个水域的水质、沉积物、浮游生物指标对总得分的贡献率来看，莱州湾水域沉积物指标的贡献率最高，其中沉积物镉是影响莱州湾生态环境质量的主要污染指标；长江口水域水质指标的贡献率最高，其中铜、油类和无机氮指标是影响长江口及邻近水域生态环境质量的主要污染指标；珠江口水域沉积物指标的贡献率最高，其中沉积物铜是影响珠江口生态环境质量的主要污染指标。

| Abstract: | Based on the monitoring results of water quality, surface deposition and plankton in the fisheries waters of Laizhou Bay, Changjiang estuary and Zhujiang estuary in May and August of 2002 to 2003, a comprehensive assessment was given on the ecoenvironmental qualities appling principal component analysis. The assessing results showed that the mean comprehensive quality of Laizhou Bay was relatively good, at the ordinary level, but it gets worse with time, the second was that of Zhujiang estuary, also at the ordinary level and the worst was that of Changjiang estuary, at the bad level, and it was worse in summer than in spring. Compared the contributing rates of water quality, deposition and plankton index in the three waters,the contributing rate of deposition index in Laizhou Bay was highest and Cd was a main pollution index which influences the eco-environmental quality of Laizhou Bay, the water quality index in Changjiang estuary was highest and copper,oil and inorganic nitrogen were main pollution indexes which influence the eco-environmental quality of Changjiang estuary,the contributing rate of deposition index in Zhujiang estuary was highest and Cu was a main pollution index which influences the eco-environmental quality of Zhujiang estuary. |
