Stormwater System Construction Based On Bio-environment Creation Of The Urban Landscape Environment

This paper analyzes the situation that Chinese water resource lacks, but Chinese rainfall resource is relatively abundant, and the impact on hydrological process of water resource because of urbanization, then find the root causes of the loss, pollution of water and flooding. Faced with these issues, this article put forward the stormwater system for the purpose of water purification, flood controlling and drainage, improving the ecological environment, and creating ecological landscapes, with the starting point of the need for rainwater utilization in cities, the need for eco-environmental construction, as well as the sustainable trend of landscape design.Stormwater system in this article is an ecological, ornamental and leisure rainwater utilization system with the purpose of bio-environment creation, which contains rainwater collection and sewage interception, storage, purification, infiltration and overflow.This stormwater system is divided into three systems:namely, stormwater utilization technology system, bio-environment creating system, landscape shape design system.Stormwater utilization technology system is an important technical support for stormwater system, which is mainly about the study of the technical aspects of rainwater utilization. Stormwater system discussed in this paper although make restoring the natural cycle of storms and floods as the goal, it is need to be controlled by people. So this paper studied the relevant ecological technology measures, which can achieve the objectives of the ecology and human control of rainwater.Creating bio-environment is an important method for improving ecological environment, it is not just the requirements of purification and flood control in the stormwater system, but also the requirements of sustainable landscape design. Bio-environment creating system in this paper is to study how to creat the habitat in the urban landscape environment. This paper discusses in detail the procedures of bio-environment creation and method to design the habitat elements.What landscape shape design system solve is about how to achieve the unification between the content and the form and bring people visual aesthetic enjoys. Here, apart from the general design requirements of the visual landscape, because of stormwater system's specificity on ecological significance, we would also create a unique landscape which can initiate people to the ecology cultural comprehension and the philosophy pondering. According to such request this article propose the corresponding design procedure and the method about the landscape shape design.According to the three systems above, the paper studies several commen patterns of stormwater system, which can be the reference for practice use. At the same time, the paper do study of practice case, for example, the Yan'an mountain park and the ecological small square, which further demonstrate the theory method stated above. And the characteristic technical measures provide reference for other cases with the same climatic conditions.
