Based On Rainwater Collection And Utilization Of Urban Park Landscape Design Research

As the source of life of the water resources, is one of the most basic elements of human survival and development. However, such problems as shortage of water resources, serious water pollution, water quality deterioration in the accelerating urbanization process, under the influence of gradually highlighted, caused the widespread concern of the whole society. Is closely related to the rain of the city park green space system annual water demand is huge,sustainable use of research should be as a key part of the city park green space system, how to use effective means and measures to realize the rainwater utilization in the city park, is the focus problem discussed in this paper.Based on a series of water problems in a city as the research background, analyzed the water consumption in urban park significance of rainwater collection and utilization in the body,according to the domestic and foreign research present situation and related theory, put forward the principle of rainwater collection and utilization of and concrete measures and methods.The innovation of the paper is the city park as the carrier, analysis in the city park can concrete implementation way of rainwater collection and utilization, and put forward a series of feasible measures, as a city park for rainwater collection and utilization of sorting out the train of thought.Combined with the shop for rainwater collection and utilization, is divided into how to collect on pavement permeability and permeability in the shop is on how to collect; Combined with the green space of rainwater resource utilization, divided into concave type under the rain garden green space, and plant grassed waterway these three aspects; Combined with water and rainwater collection and utilization of landscape sketch, how to collect on the ecological wetland and lake are analyzed and the use and the use of landscape sketch how to collect and use; Combined with construction of rainwater collection and utilization of specific methods,from the characteristics of urban park buildings, roof and roof two methods are analyzed in detail.Using Dandong city south of Dagushan scenic area as the practice of rainwater collection and utilization of place, proposed the rationalization proposal, and analyses the reconstruction of the economic, ecological and social benefits.This thesis emphasizes the rational utilization of rainwater in urban park the importance of this precious natural resource, and for the early realization of the sustainable development of urban rainwater collection and use of concrete Suggestions are put forward, in the city park for the future to provide reference for rational utilization of rainwater resources.
