天津淡水生态系统大型底栖动物群落结构特征研究
|
摘要
天津作为北方最大的沿海开放城市,水生态系统非常丰富,分析淡水生态系统大型底栖动物群落结构特征对构建大型底栖动物生态监测网络,开展淡水生态系统健康评价意义重大。研究结果表明,天津淡水生态系统大型底栖动物主要以寡毛类和摇蚊类等耐污染物种为主。引滦入津流域、于桥水库和大黄堡湿地大型底栖动物种类丰富,水生态系统保持相对良好;尔王庄水库和北大港水库大型底栖动物种类少,丰度低,生态系统受到了较严重的人为破坏。
Macrobenthic community as the largest coastal open city in Northern China,freshwater ecosystem in Tianjin are more than abundant. The conclusion of macrobenthic community of freshwater ecosystem in Tianjin is of great significance for construction of macrobenthic ecological monitoring network,assessment of freshwater ecosystem health. The research showed major macrobenthics in Tianjin freshwater ecosystem were oligochaetes and chironomids. Macrobenthic community species in Luanhe River Basin,Yuqiao reservoir and Dahuang Fort Wetland were more than abundant and ecosystems were relatively good,while macrobenthic species in Erwangzhuang Reservoir and Beidagang Reservoir were few,which meant that ecosystem of these two reservoirs had been seriously damaged.
