The Research On Natural Water Ecological Utilization Strategy Of River Valley Town In Qinling

With the proposal of the rural revitalization and the beautiful village's strategy,the development of towns in China has made rapid progress in recent years as well as great progress on towns planning and building qualities.During this development process,the contradiction between development and nature resources has become more and more prominent.Today,with the advocating of saving resources and the sustainable development theory,the environmental problems of towns and villages are attracting more and more attention.This topic focuses on water resources,the most indispensable resource for human life,and proposes the concept of “natural water” based on the actual environment of towns.This thesis explores an adaptive natural water ecological utilization strategies based on the special development status and topography of towns and villages.At present,the research on the ecological utilization of water resources in the city has been quite successful,but there barely has researches analysis about towns and villages.Therefore,it is necessary to learn the existing experiences in the city and apply it to towns and villages so we could improve the natural environment and save water resources.This thesis takes the Qinling River valley town as the research object,the detailed research on 79 towns and towns in the Qinling area leads to a specific picture of the topography,construction layout,landscape status,building roof,drainage method,courtyard status and river status of the town.Through the research,researchers found that towns and villages lack ecological landscape analysis during the process of planning and construction.At the same time,the wrongful treatment(the quick discharge)of rainwater leads to material pollution for river water.Secondly,in the process of construction,the township did not consider the natural hydrological cycle,the ecological landscape and the ecological destruction of the river channel,all these elements lead to the traditional “development-governance” model.What's more,the lack of ecological considerations,multiple perspectives evaluations during the water resources utilization design and the water landscapes construction also affect the environment.This thesis focuses on the natural water ecological utilization strategies of the Qinling River valley,combines the use of low-impact development,human settlements environmental science,watershed ecology,sponge city,and other related theories as for the research basis.Considering the previous township survey data,the characteristics of natural water in townships were analyzed.Besides,the relationship between township layout,township architecture,township landscape,and natural water,ecological benefits were further analyzedas well.This study further discusses how the natural water utilization methods should apply to the special terrain of Qinling River valley and purpose the garden rainwater utilization,waterscape space building,“river water ”strategy and river water landscaping strategy.These researches provide valuable reference and theoretical guidance for the natural water utilization of Qinling River valley towns.
