关于河道改扩建工程中水生植物对生态环境的净化OA

In the development of modern cities,the single function of river channels in cities can no longer meet the growing needs of people,nor does it meet the requirements of ecological civilization construction.Therefore,under the slogan of protecting the natural environment and promoting harmonious development between humans and nature,upgrading and transforming old river channels has become one of the urgent goals that major cities need to achieve at present.By planting aquatic plants in rivers and establishing ecological river channels,not only can the goal of improving water quality and enhancing river functions be achieved,but it also provides leisure and walking places for surrounding residents,achieving the goal of sustainable development.
