| With the development of urbanization,the economic development of the city and the living standard of the people have been greatly improved.At the same time,due to the change of land use pattern and situation,the lack of water resources,frequent floods,insufficient groundwater resources,etc.A series of environmental problems have become increasingly prominent.Residential area as an important part of the urban area,its rainwater utilization effect on the city’s rainwater use work has an important impact.How to combine the environmental design and rainwater utilization work in the residential area,improve the current situation of urban water shortage and meet the water demand of urban landscape will be one of the main contents of this paper.The study on the utilization of rainwater in the urban environment based on the landscape pattern has made outstanding achievements in the developed countries,but the research on the landscape utilization of rainwater in China is still at the initial stage.Therefore,the main research direction of this paper is to analyze the characteristics of the residential area in China,and combine the relevant concepts,theoretical achievements and concrete practical experience of rainwater utilization to explore the possible methods and ways of landscape utilization in residential area.Through the analysis of the theoretical and practical experiences of rainwater utilization at home and abroad,it provides reference and technical support for the implementation of rainwater utilization landscape in Zhengzhou residential area.Then,the necessary potential and necessity of rainwater in Zhengzhou City were analyzed,and the actual available amount of rainwater in Zhengzhou City in 2016 was calculated.It laid a foundation for reaching the target of rainwater landscape in residential area of Zhengzhou City.Background support.On the basis of the above,this paper analyzes the principles and influencing factors of the residential area environment,and discusses the relationship between thelandscape and the climatic characteristics of Zhengzhou from the aspects of buildings,plant configuration,pavement pavement,water landscape and so on.Using the combination of landscape design and methods.Finally,through the field investigation and the present situa tion analysis of the residential area in April of Zhengzhou City,the problems,the balance of water balance and the comprehensive benefits of rainwater utilization landscape are explored,and the rainwater utiliation suitable for the residential area is put forward Landscape of the overall train of thought,design details and means of measures.Based on the theoretical experience and practical results of the existing rainwater utilization,this paper explores the implementation of rainwater utilization from the perspective of landscape design,with a view to bringing reference value to the popularization and utilization of rainwater utilization landscape in the future residential area. |
