Study On The Ecological Restoration And Landscape Design Of The Rivers In The Southern Mountainous Area Of Ji'nan City

The damage to our river ecosystem's structure and funct ion caused great harm of water ecosystems sustainable use of water resources, biodiversity.It can also cause great harm of human health and safety of drinking water. Many governments attach great importance to the damaged rivers and water of ecological restoration.Though people at home and abroad have done a lot of research about river restoration, but it is still lack of theories and research methods.In view of this, the present study for rivers in the southern mountainous area of Ji'nan. The problem includes that nitrate nitrogen pollution, seasonality farmland erods river bank erosion and river landscape are serious. From the viewpoint of river ecosystem function we do the recovery.Ecological restoration methods were discussed and we use it to build a suitable implementation of rural development and historical heritage of ecological landscape reconstruction mode. We verified its practicality from the theoretical and technical aspects.The results of this study can provide ecological management cases abo ut medium and small rivers in northern and the scientific basis and reference cases about the ecological restoration of the country's rivers.In this study, we are based on practical problems, improve the target of the ecological environment of river, and use Jinan three southern mountain River Basin project as a platform.We use ecological technology and landscape construction method to slove the problem.Then we want to achieve the target that we can improve the South of Jinan three-basin water quality and ecological environment governance. Our research results are follows,(1)We studied phytoremediation water from water quality characteristics of Jinan southern mountain three river basin and north Shahe River demonstration area. We explored 9 emergent plants, 4 floating plants, 6 submerged plants that have purification capacity. We use water plants to ecological restoration, water purification both received good effect, but also the formation of a green landscape.(2)We did the investigation about the There River Basin and the North Shahe demonstration area and did the biodiversity statistics of community model.Then through the analysis of the water quality purification effect and landscape effect, we selected 16 aquatic plant community collocation, and from 16 community we selected 5 optimal community for plant configuration.(3)We did landscape ecological reconstruction work at Three River Basin confluence and North Shahe demonstration area, mainly including plant configuration, construction of ecological revetment, increase biodiversity and hard landscape design a variety of content. In this part,we did the plant configuration by aquatic plants, riparian plants and road forest based on pioneer aquatic plant species selection and community preferred, and increased hydrophilic facilities, recreational facilities, paid attention to the historical heritage and modern development, completed a nearly natural ecological landscape design work.
