The Research On The City Park's Water-saving Planning Of Landscape

City park is the important green infrastructure. It's the important part of the city and playing an important role in improving the city's ecological environment and people's living quality. In the background of water shortage and water environmental degradation all over the world, saving water become the inevitable choice of realizing the sustainable development of the society. City parks are the subject of water consumption.And also they have certain storage function and huge water-saving potential.At present, the construction of resource-efficient gardens is an important trend of landscape designing. People had do many researches, include of rainfall and flood's collecting and using,water-saving technologies of green space's maintaining and managing. In this paper. I took the city park as the main object of my research, emphasized water conservation consciousness in the landscape planning and design of city park. In this paper, we want to find the right way of landscape planning and design to save water with the water saving theories and technology.This paper analyzed city park's water supply and demand,the water resources problems in parks and the causes of those problems; summarized the general connotation of water-saving planning and design in city parks.Then, combining with related theory and practice about water-saving at home and abroad, we put forward corresponding countermeasures to landscape planning of city park including rainwater's collection and utilization, water recycling system planning, water-saving planning of plant landscape and waterscape. This paper discussed how to combine the rainwater collection and water reuse technique with city park's landscape planning and design. It emphasized to chose compatible plant variety and optimize plant configuration mode. There also have some researches about the area controlling of artificial waterscape, ecological building mode of bulkhead and bottom of the pool.Finally, we had investigated some city parks in chongqing and taken four parks as examples like E Lin Park,Hong En Si Park and so on. The research was focused on the rainwater collection and utilization, irrigation technology, plant and waterscape planning, etc.In the paper it summarized the existing problems of water-saving landscape design in those parks and put forward the corresponding countermeasures and measures to improve water-saving efficiency.
