Water Saving Irrigation Technology Of Landscape In Tianjin Area

With the rapid development of social economy and urban construction,natural resources and ecological environment are facing tremendous pressure,the contradiction is becoming more and more prominent.Especially in the background of water resources shortage in China,many cities are in the direction of sustainable development,which is filled with a lot of the phenomenon of water resource.Many urban landscape design is lack of macro planning,not according to the local water resources and the functional requirements of the site,a large number of water resources,but also to lose the local characteristics of the landscape.How to save water resources in urban landscape greening is one of the urgent problems to be solved in the design of urban landscape greening.Especially the application of water saving irrigation technology in urban landscape gardening has been recognized.At present,the research on the use of recycled water in landscape water management in China is relatively backward,and the water resource utilization rate is low,the water consumption is not perfect,the water resources waste is very serious,and the city water consumption is increased.Therefore,the study of urban green space saving irrigation design will further improve the ecological environment,can effectively improve the utilization efficiency of irrigation water and the use efficiency,for urban green irrigation to achieve the real meaning of water saving has practical significance.In this paper,the landscape irrigation technology in Tianjin area as a starting point,in the full study of domestic and international urban landscape irrigation technology of the relevant theory and analysis of specific cases,on how to better use of water-saving irrigation technology to conduct a comprehensive study,it has a certain meaning of the design method.This research aims to expand the design ideas for the designers,to provide a reference for the construction of water-saving irrigation green space in urban landscape greening.Based on the analysis of the literature data,this paper analyzes the severe situation of water shortage in the present era,the development of the current urban landscape water saving irrigation technology,and finds out the existing problems of urban green irrigation.And taking this as the starting point from the city garden green water saving irrigation optimization evaluation and all kinds of irrigation methods and other aspects of the basic equipment to do a thorough research.Based on the combination of theoretical analysis and practice,some technologies and management measures of water saving irrigation in urban green space are summarized,and the principles of urban green water-saving irrigation design are summarized.
