Study On Landscape Construction Of Jianghuai Watershed Based On Rainwater Management And Utilization

Water resource is the most active and indispensable element on the earth,which restricts the production and development of human beings.Water resource problem has become a strategic problem of sustainable development in China.However,many areas lack of rational use of water resources,so the author hopes to build a reasonable water storage site through the combination of landscape architecture and water resources.Based on the overview of the basic concept of macro,the summary of the research status at home and abroad,this paper selects the Jianghuai watershed area as its analysis object,and provides practical support for its own design cases through field investigation of various places.Finally,the author designs a set of rainwater storage facilities in the site through his own practical case,and makes it a sponge site to promote the utilization of surrounding water resources.The main research contents and results of this paper are as follows:(1)The concept of rainwater management is summarized.(2)Field investigation of different sites of rainwater management and utilization.In different sites,people have designed a series of landscape projects of water storage and drainage combined with nature.For example,open cut ditches,dry streams,water storage equipment and so on.(3)The analysis of the characteristics of rainwater and the ways of rainwater management and utilization in Jianghuai watershed,as well as the investigation of rainwater management and utilization in relevant agricultural parks,lay the foundation for the combination design of the agricultural park site and rainwater management and utilization.(4)Based on the analysis of the current situation of the Dagu reservoir in Wuwei County,and on the basis of the development and utilization of its current water resources,a new agricultural park integrating rainwater purification,rainwater utilization,rainwater storage and reasonable rainwater discharge is designed and planned.It can not only meet the needs of residents for rainwater use,but also provide residents with a resting place to attract tourists.
