The Research Of Urban Green Space Planning Based On Rainwater Resources Utilization

Along with the development of urbanization, the shortage of water resource problem poses a serious challenge to many cities. Rainwater is a kind of resource that can be used directly and important part of water circulation system of nature, at the same time, it is the key effect to adjust, supplement water resource and improve, protect environment. So rainwater is an important approach to continue development of water resource. Green space is the best ecological infrastructure because of its osmotic effect. At present, the green space planning only focus on quantity index, and neglect its ecological function. In this paper, researched the urban green planning based on rainwater utilization, in order to establish a new method.Researched the developing progress and current stations of urban green space planning; decide the plan guideline of this paper: city is a part of region, the urban ecological environment directly correlated with the region's, plan urban green space from the angle of regional space. It is the root of rainwater utilization to maintain its natural hydrological cycle, so should respect the natural ecological progress and function first, in order to improve the ecological effect of green space more effectively.In the end, this paper applied above planning theories and methods to practical urban green space planning in Zhanjiang.
