| 摘 要： | 淀山湖是上海市内陆水域最大的淡水湖泊,主要的淡水渔业水域和水产品来源地,也是重要的水生生物保护基地。为了评估增殖放流和生态环境变化对淀山湖鱼类群落结构变化的影响,本研究以2010-2012年淀山湖的渔业调查资料为基础,对该湖泊的鱼类优势种组成和多样性指数进行年际变化分析,并应用丰度生物量曲线方法对该湖的鱼类群落状况进行分析。结果表明:2010-2012年淀山湖鱼种类数基本稳定,基本鱼种组成变化不显著,优势鱼种组成趋势渐以小型鱼类为主;群落结构多样性指数年间差异不显著(P0.05);ABC曲线显示2010-2012这三年淀山湖群落的数量优势度曲线均高于生物量的优势度曲线,鱼类群落结构仍处于严重干扰状态。因此,建议改善增殖放流鱼种和加强渔业管理,以维持淀山湖鱼类群落的稳定。

| Abstract: | As the biggest local lake, Dianshan Lake plays an important role in fishery, aquatic food supply and conservation for aquatic living resources for Shanghai. In this study, we analyzed the annual variations on diversity of fish community and its status of this lake based on the survey data in Dianshan Lake from 2010 to 2012. The results showed that fish species composition was similar among the three years and the dominant species tended to be mini type fish of fish composition. It indicated that the Diversity Indices of fish community in Dianshan Lake were not significantly different among the three years (P>0.05). Moreover, the analysis of k dominance curves showed that the fish community was disturbed in Dianshan Lake in the three years. It is necessary to adjust management rules to maintain fisheries resources by improving water quality, relieving the fishing intensity, and improving fish stock enhancement in this lake. |
