Application Research On Rainwater In Landcape Design In Urban Block Scale

With the rapid urbanization process in China, the majority of our cities are facing a series of ecological problems caused by water shortages. In urban water resources, the rain is the most basic, the most direct and economical resources while rain can also play a regulating groundwater resources and improve the ecological role of urban micro-climate. In the specific urban design and landscape planning in regional, district as an integral element of the ecological impact of urban development of the city has a very important role. Therefore, the establishment in the neighborhood and landscape scales rainwater systems combining application system is not only beneficial to the city garden maintenance cost savings, more conducive to improving and maintaining natural water cycle; rainwater utilization can be achieved while the urban ecological water conservation, soil erosion control city and water logging, reduce the load on municipal sewer and treatment systems, and improving the ecological environment and other targets. Seeing this, the convergence of urban neighborhoods in both scale and architectural landscape ecology contact is an effective way to short-term economic and ecological benefits of long-term double-income, its technology for the modern city has a broad and far-reaching significance.For the application of neighborhood scale rainwater is divided into four parts:The first part is the status of research on China’s water resources and rainwater utilization status, research progress by reviewing past practices and elaborate gardens with water, to determine the significance and core direction; the second part is the theoretical research, through domestic and international research on cognitive and basic concepts of successful experience in the discovery and analysis of specific urban neighborhoods in rainwater utilization problems and propose necessary city blocks rainwater in landscape design applications and feasibility; the third part is the in-depth study, summed up the whole first block scale rainwater in landscape design system design patterns, principles and steps, and then combined with Chinese characteristics and advanced technology from abroad, from the road, green building, four square city blocks were interpret the landscape to create a detailed breakdown of rain water conservation practices and specific applications; the fourth is an instance of applied research, combined with Shen Fu Metro project examples to validate methods of Chapter III, specific city block shows by example the rain made its rainwater use and landscape design combined with the overall approach to the system design process from each element, and use node design.Through a detailed analysis of the necessity and feasibility of rainwater utilization of existing urban areas, combined with advanced technology and case, the system proposes adapted to block rainwater utilization of design patterns and design steps, explained in detail the composition of the four core elements of neighborhoods--urban roads, buildings, green spaces, squares detailed classification and specific practices in rainwater utilization. On the basis of theory, Shen Fu Metro, for example, to further demonstrate and validate the specific practices of rainwater utilization in the neighborhood of the paper summarized enrich the connotation of the theory, but also the whole idea of the concrete implementation of the application to the rain the actual design of the neighborhood, and through neighborhoods internal synergies between neighborhoods and neighborhood concept, to promote the protection and development of urban water resources. As for the urban space itself, but also through sustainable use of rainwater, creating more ecological-efficiency, while also making it have more aesthetic value and provide more reference for landscape architects, urban planners of future designs.
