Urban River Course Landscape Planning And Design Based On Plants Water Purification

With the acceleration of the urbanization process,due to industrial emissions and daily sewage,domestic urban river pollution is serious,having a very bad influence on the city's landscape,quality of residents' life and the healthy development between economy and the environment,so the control of river pollution is urgent.With the progress of research,the aquatic plants-based bio-ecological technology has advantages of low project cost,low running cost and high efficiency,and it is increasingly applied to sewage treatment of urban river landscape.From the point of aquatic plants water purification,this paper aims to plan and design the urban river park.As aquatic plants are the most important part in the system,the screening of aquatic plants is critical Based on the analysis of the existing experimental research,under the premise of taking the relevant factors,such as water pollution concentration,low temperature condition and planting density,all into consideration,this paper summarizes the principles of how to screen the aquatic plants in the plant water purification system and configure a stable and efficient multilevel plant pond and floating-bed system This paper chooses reasonable lot to carry out development and design,so that the plant water purification and ecological park can fit well.From the point of improving the urban river water quality and improving the ecological environment,we are going to create a urban river landscape which takes aquatic plants water purification as the main part and covers ecological green space,science education and entertainments.
