摘要
长沙市梅溪湖作为梅溪湖片区的绿心,是湘江新区核心区域的城市"海绵体",其水环境质量的稳定是片区开发建设的重中之重。但随着梅溪湖片区的集中开发,周边商业、餐饮业快速发展,人流量逐步增加,生态环境破坏风险加大,对梅溪湖水生态环境和景观生态的维护带来了极大考验。为改善梅溪湖生态环境,采用生态优化处理、营养级串联调控、营养物生物过滤、营养物生物吸收等生态治理技术对梅溪湖景观水体实施净化工程。实施生态治理技术后,对梅溪湖湖区水质进行了监测,结果显示梅溪湖水质由地表水Ⅳ类水提升至Ⅲ类水,初步形成了"水清岸绿"的风景。梅溪湖生态治理修复工程的成功实施为相关工程的建设提供技术借鉴。
As the green heart of the Meixi Lake area in Changsha City,Meixi Lake is an urban"sponge"in the core area of the Xiangjiang New District.The stability of the water environment quality of Meixi Lake is the top priority of the development and construction of this area.However,the concentrated development in the Meixi Lake area has led to the rapid expansion of surrounding commerce and catering industry with a large flow of people,which has increased the risk of ecological damage.It also brought a great challenge to the protection of the water environment quality and landscape maintenance of Meixi Lake.In order to improve the water ecological condition of Meixi Lake,we have conducted purification projects for the water body of Meixi Lake using ecological treatment methods such as ecological optimization treatment,various regulation of trophic levels,bi-filtration and bio-absorption of nutrients.After the implementation of the ecological treatment technology,we monitored the water quality of Meixi Lake.The results show that the water quality of Meixi Lake has been improved from GradeⅣto GradeⅢfor surface water,initially forming a landscape of"clear water and green banks".The practice of ecological management and restoration of Meixi Lake can provide technical reference for the construction of related projects in the future.
