The Sponge In Urban Ecological Landscape Design Research

With the rapid development of China’s urbanization process, our country also have done much damage to the ecological environment in the city, the natural disasters occurred frequently, the serious pollution of water resources and the serious shortage of urban water resources is the important ecological problems faced by the current. Based on these is eyebrow urgent environmental problems, the government proposed the sponge in recent years the requirement of urban construction. However sponge city by the low impact development concept as a guide, make field development before and after the development of the basic characteristics of hydrological remains the same, so as to achieve effective reduction of rainwater runoff and rain flood peak runoff, reducing the purpose of the rain in the process of runoff pollution contaminated, and will be closely linked to the whole water cycle system in the city, and to form a common as a whole, through natural ecological landscape and artificial means to achieve the sewage purification and the purpose of the ecological restoration of water environment.In recent years, people about the importance of the rain has been on the rise, the relationship between water environment and the rain, also got the attention of people from all walks of life, but in combination with the practice of landscape, the rain has just started in our country, also presents the general phenomenon of fragmentation, the rainwater resources use landscape system with the method of comprehensive analysis of the research. By seeking more professional collaboration, multiple disciplines, the original ecological wetland, stormwater management and water pollution problems, to carry on the scientific and systematic analysis, so as to realize the ecological function of water environment.Rainwater utilization is generally low in our country, and municipal drainage facilities is also larger defects, in the actual construction project on the use of the rainwater ecological research is very few, all walks of life are relatively independent and lack of coordination, urban drainage pattern is the main emissions by urban pipeline system, this not only increases the rainwater pipeline pressure, the great waste of water resources, and the storm hit, also urban waterlogging disaster happens, especially in big cities is most serious. To the management of the science of the rain, rain to ecological benefit to the construction of our city, the rainwater management, as urban green infrastructure construction, to restore the city’s ecological environment provides the basis.In the process of research sponge city theory, this paper thinks the sponge city construction, urban green space plays a promoting water circulation system and control the effect of storm runoff, so after the research content of low impact development philosophy, summarized in the field of ecological landscape planning and design process of the design concept, and put in a specific practice project as an example, introduced in urban space design, guided by the idea of sponge by summing up the characteristics of urban design, sponge sponge urban design main design content and design principles, this paper will also be combined with the practice of domestic and foreign cases of systemic argument on in this paper.
