Rainwater Resource Avail Mode Research Of Linyi City

This paper based on lots of reading, summarization and comprehensive analysis of domestic and foreign research of urban rainwater utilization. Based on the theme of the sustainable use of water resources and ecological environment protection. Guided by the theory of sustainable development. Studied by the region’s social, economic, resource, ecological and environmental development. Applied social science and natural science theories, methods and techniques. Studied by the small urban rainwater utilization patterns and related measures.First, through the use of domestic and urban water resources development research, practice application, research, development trends shows that is necessary requirement for sustained development to rainwater utilization,which is an effective way to solve the shortage of urban water resource.Second, analysised the situation and social development of LinYi City, revealed the evolution of its rules and trends. analysised the water use history and status of water resource utilization.Third, discussed the impact of urbanization on urban climate, surface runoff, watequality, groundwater, flood control, waterlogging, and municipal construction. According to theory of urban rainwater utilization.Come to the potential model of urban rainwater resources can be achieved.According to theory of urban rainwater utilization.Come to the potential model of urban rainwater resources can be achieved.The research has analyzed the constraints require of utilization of urban stormwater models. Puting forward for the rainwater utilization patterns which is suitable for LinYi CityFourth, rainfall based on characteristics, rnalysised the potential and predictive of the amount of rainwater resources of LinYi City. Obtained its water resources to achieve. Then, proposing the corresponding implementation measures.This paper take the theoretical method as main line,guide the practice for the purpose, calculate and analyze the rainwater resources of LinYi City, The results show that reasonable utilization of city’s rainwater resources not only increases the water resoures supply and recharges groundwater, relieves the tension between water supply and demand in cities, but also improves the urban eco-environmen and realizes the sustainable utilization of water resources,which can bring about great economic benefits, social and eco-environmental benefits. Which provides a scientific decision basis for carrying out the use of rainwater resources and building national water-saving cities.
