为探究水生植物修复在校园景观湖生态治理和景观提升的实践效果,本研究以中国科学技术大学西校区三塘水环境治理为例,使用生态修复技术,结合截污控源和生态清淤,对治理后的水质、植物群落变化、景观指数得分等进行调查和分析,评价景观湖生态治理和景观提升效果.结果表明,采用水生植物修复技术,构建以沉水植物为优势生物的水生态修复技术,对景观湖水质、生态和景观改善具有良好的效果.生态治理后,水体氨氮、总氮、总磷、化学需氧量和透明度等指标均能够维持在Ⅲ~Ⅳ类水,水质长期稳定在Ⅳ类水,水生植物覆盖率提升到了 65.64%,水生植物物种数显著增多,景观指数明显提高,附近师生对治理效果较为满意.本工程可为后期其他高校老校区水环境改造和新校区水环境建设提供参考价值,并针对性提出引入水环境景观指数评价标准,以期进一步完善我国的绿色校园评价体系.
Practice study on ecological management of landscape water body——Taking landscape lake of University of Science and Technology of China as an example
In order to explore the practical effects of aquatic plant restoration on ecological management and landscape improvement of campus landscape lakes,this study took the Santang water environmental management of the West Campus of the University of Science and Technology of China as an example,and used ecological restoration technology to investigate and analyze the water quality,plant community changes and landscape index scores after treatment,combined with pollution source control and ecological dredging.To evaluate the effect of ecological management and landscape improvement of landscape lake.The results showed that the application of aquatic plant restoration technology and the construction of water ecological restoration technology with submerged plants as the dominant organisms had a good effect on the improvement of water quality,ecology and landscape of landscape lakes.After ecological treatment,the indexes of ammonia nitrogen,total nitrogen,total phosphorus,chemical oxygen demand and transparency of the water can be maintained in class Ⅲ~Ⅳ water,and the water quality is stable in class Ⅳ water for a long time.The coverage rate of aquatic plants has increased to 65.64%,the number of aquatic plant species has increased significantly,and the landscape index has increased significantly.The nearby teachers and students are more satisfied with the treatment effect.This project can provide reference value for the water environment transformation of the old campus and the water environment construction of the new campus in other universities in the later stage,and put forward the evaluation standard of water environment landscape index in order to further improve the green campus evaluation system in China.
