【摘要】 为探索成都市简阳三岔湖湖滨带的生态构建方法,为西南地区具有富营养化趋势的水体及湖滨带生态构建工作提供参考,在三岔湖西南侧新民乡的湖滨带规划设计建设了以内湾湖水循环净化工艺为核心的示范工程,并对其修复效果进行评估。结果显示,示范工程建成后,湖滨带的氨氮浓度、总氮浓度、总磷浓度明显下降;浮游植物和浮游动物的种类明显增多,物种多样性增加,对应的多样性指数、丰富度指数均变大,均匀度指数变化不大;湖滨带植被种类、覆盖率也都有所增加。更多还原

【Abstract】 In order to explore the ecological construction technologies of the lakeside zone in Sancha Lake in Jianyang,Chengdu,and provide the reference for ecological construction of eutrophic water in the southwest of China,we constructed a demonstration project with inner bay lake water recycling purification process as the core in the Xinmin town,southwest of Sancha Lake and evaluated the remediation effect of the projects. The results showed that, after the project was completed,concentrations of NH3-N,TP and TN in the lakeside zone declined significantly,the species of phytoplankton and zooplankton obviously increased. With the increase of species diversity,the Shannon-Wiener index and Margalef index increased,while the Pielou index changed little. The species and coverage of terrestrial vegetation in lakeside zone increased.更多还原
