| 摘 要： | 结合林庄港的生态修复工程建设,系统地研究了木栅栏砾石笼生态护岸的技术要求和生态效果.现场监测结果表明:试验河段内河道水体中CODMn,TN,TP的去除率分别达到20.7%,13.9%,21.1%,同时生态护岸建设前后河段内底栖动物结构、种类和优势物种均出现明显变化,底栖动物的类群发生了由耐污类群为主向中间类群为主的转化,说明木栅栏砾石笼护岸对林庄港河流生态系统的改善和修复有良好的效果.

| Abstract: | The technical requirements and ecological effects of the technique for ecological bank protection by wooden fences and gravel boxes were systematically studied for Linzhuanggang ecological rehabilitation project in Taihu Lake Basin.According to the field monitoring,the ecosystem of the tested river courses was improved evidently: the removal rates of CODMn,TN and TP reached 20.7%,13.9% and 21.1% respectively;the structures and species of zoobenthos changed obviously after the ecological construction,and the dominant species of zoobenthos changed from pollution-tolerant ones to mesosaprobic ones.As a result,the ecological bank protection by wooden fences and gravel boxes is effective for improvement and rehabilitation of Linzhuangang river ecosystem. |
