Research On The Water Sensitive Green System Of Infrastructure Corridor In Harbin

Water problem in city is becoming increasingly serious.Water promlem concerning the limited water resourse,water pollution and waterlog ging.With the development of the city,the underlying surface impervious area is increasing.For this reason,the stormwater can not complete the infiltration and filtration through the normal water circulation system.It leads to the stormwater directly disc harge into the drainage pipeline networks before flowing into the receiving water.The frequency of heavy rainfall increased with the rising of global temperatures.Once the city suffered heavy rainfall,the rainfall will lead to waterlogging when it beyond the ability of the pipeline netwok.Traditional urban infrastructure can not meet the need for the development. Infrastructure corridor and drainage pipeline networks update difficultly.Our city Harbin should begin the water sensitive planning respounding for the eco-sponge city policy.Considering the trendency of the infrastructure corridor and the green space system,the study should take foreign theory and pratice as the example with the background of water problem in city. It start the function of the green space to storage and regulate the rainflood with the composition of the green space.It take usage of the rainfloods which beyond the ability for the drainage pipeline networks.It describes the function of the green space system in the urban infrastructure corridor system combining the urban drainage environment and the history of the green. Based on the meteorological factor, hydrologic condition, rainfall circumstance in harbin to study the scale of the green space and using the quantitative research methods. Choosing the typical area and taking usage of the formula of rainstorm to help the research. By connecting the green space to the green space system to help the pipelines regulating and storing the rainfloods. Optimizing the layout of the green space combining the scale and morphology element.It discusses the methods to layout the green space of different scenarios.Faced with the serious water problem, it study the green space system and the infrastructure corridor with the knowledge referring urban design theory, civil engineering, landscape ecology and landscape architecture. It takes the green space system into the infrastructure corridor system and provides with the new methods and idea. Exploring the innovative model for infrastructure corridor system. It gives the opinions in optimizing the infrastructure networks.Concentrating with harebin area, it analysies the composition of the green space system,and provides reasonable layout for green space through field survey. Forming completely green space system under the concept of infrastructure system is our purpose. It can protect the green space for the infrastructure can not be change. The study does the basic research in eco-sponge city of harbin. It has guiding significance to the infrastructure and green space in city.
