Research On Design Of Water-saving Irrigation In Urban Greenbelt

Along with our country social sustained rapid economic development, science and technology greatly improved and accelerating the pace of urbanization, people on the residential environment puts forward the new higher requirements, sought to establish safe, healthy and comfortable urban environment has become most of the city residents consensus. City's green environmental quality has become the measure of a city development status of important indexes. Urban ecological system has the self-purification urban green space, in maintaining ecological balance, and beautify the city urban landscape, improve the urban grade and aspects of improving urban ecological environment plays very important role, this is of urban ecosystem, other infrastructure is unable to substitute. Urban green space sustaining urban sustainable development is regarded as one of the important factors, it absolutely is not an option, not the landscape decoration only for meet the people have a rest, entertainment, recreation activities need, but maintaining the city residents place necessary for survival to the physical environment space. However, with the development of national economy and the improvement of environmental awareness citizens of urbanization and social development trend of urban construction activities, used for urban greenbelt is more and more obvious in irrigation requirement increasing year by year, lead to more urban greenbelt maintenance cost is high.Plants survival and growth cannot leave the water in China, and many areas of many drought, frequent sandstorms phenomenon, severe desertification, water supply disorders and ground water levels fall facts and so on, has pointedly prompted the world to pay attention to the problem of water shortage. Human survival in case of increasing scarcity of water, water-saving irrigation of urban green space in the Landscape by re-understanding. At present ,our country garden water management in renewable water use technology research is comparatively backward, generally with water or ground water, garden water for main water utilization rate is low, water-saving system construction is not perfect, water resources waste phenomenon is very serious, intensifies the municipal water strain degree. Therefore, the research of urban greenbelt water-saving irrigation optimization design will effectively improve the ecological environment, which can effectively improve the utilization rate of irrigation water and use efficiency of urban greenbelt, the true sense of the irrigation water to be practical.This article will urban greenbelt irrigation technology as a starting point, SWOT analysis on current urban greenbelt development status of water-saving irrigation projects of urban greenbelt water-saving irrigation itself, the advantages and disadvantages, opportunities and the threat to the analysis, find out the existing problems of urban greenbelt irrigation. And so as a breakthrough, through to the original technology improvement and the introduction of new technology of urban greenbelt water-saving irrigation optimization design research, its main including irrigation modes of selection and sprinkler irrigation equipment selection and the design of landscape three aspects. Theoretical analysis and practice in the basis of the combination of the urban greenbelt, summarized the current water-saving irrigation some technology, management measures and exploratory induces urban greenbelt water-saving irrigation optimization design guideline for the future, in order to better promotion and development of urban greenbelt make razor-thin water-saving irrigation of the force.
