摘要
以“食藻虫引导水下生态修复技术”在上海市花博园水系原位生态修复的应用案例为研究对象,介绍了沉水植物群落快速恢复关键技术及生态系统运行期的主要调控措施,通过跟踪评估生态修复后水域水质指标及系统稳定性,为城郊河湖一体富营养化水系治理提供经验参考与理论支撑。沉水植物在城镇水体水环境提升方面发挥着重要作用的同时,废弃后若处理不当又会形成二次污染,因此进一步探讨了沉水植物等典型城镇废弃物资源化处置的问题,以期为营养盐转移上岸途径并资源化循环利用提供新思路。
Taking the application case of ecosystem recovery technology of water body by Daphnia magna in the in-situ ecological restoration of water system in Shanghai Flower Expo as the research object,the key technologies for rapid restoration of submerged plant communities and the main control measures during the operation of the ecosystem are introduced.By tracking and evaluating the water quality and system stability of the water area after ecological restoration,it provides empirical reference and theoretical support for the management of eutrophic water systems in rivers and lakes in the suburbs.Submerged plants play an important role in improving the water environment of urban water systems,but they will cause secondary pollutionif not properly treated.Therefore,the problem of resource disposal of typical urban wastes such as submerged plants is further discussed,in order to provide new ideas for the transfer of nutrients to shore and resource recycling.
