Study On Comprehensive Benefit Evaluation Of Spongy City Construction In Jiangxinzhou Island,Nanjing

In response to a series of urban problems emerge in the process of rapid urbanization,China offered to sponge city for urban development mode innovation breakthrough,in the construction of ecological civilization and exploring a new path of urbanization on the fusionAt present,the understanding of sponge city concept still exists in the problem of water control and technology dependence,focusing on the urban drainage system and the utilization of rainwater.The great benefit of sponge city construction has not been fully realized and fully reflected.Sponge city can not only effectively alleviate various water problem in the process of rapid urbanization,the fundamental goal is to balance the economic construction,social development and ecological improvement of the triple value pursuit,optimizing urban composite system structure "environment,economy and society".Sponge city is the benefits of a diversified,all-round,the benefit evaluation on the overall system is a complex problem,at present has not yet formed a set of mature theory and method,it also restricts the sponge to exert the functions of the largest urban constructionJiangxinzhou island is located in the Yangtze river southwest of Nanjing.Its geographical location is relatively independent,its geographical area is moderate,its ecological base is good,its existing development degree is low,and it has the innate advantage of building sponge city,and the demonstration effect is quite remarkablePromoting the construction of this study is based on "to the evaluation,evaluation to promote improvement and evaluation management",the purpose of the analysis of the central bar sponge city contribution to ecological,economic and social benefits,mainly including the rain flood management,adjust microclimate,industry drive,land value-added benefits,urban brand,science and education,culture,landscape aesthetic benefits,etc.,to build the central bar sponge comprehensive benefit evaluation index system for urban construction,choice of polygon graphic method,evaluated the central bar sponge city construction comprehensive benefits According to the results of the evaluation,the construction of sponge city in jiangxinzhou island has been effective,and the improvement of the ecological environment is more obvious,and there is still room for economic and social benefits.In comprehensive benefit evaluation on the results of all aspects of the situation in view of the central bar,discusses its on the sponge city need to focus on problems,try to put forward some suggestions,including the wisdom city urban construction,promote the sponge sponge on urban management wisdom and efficient;To build a small town of sponge to realize the multiplier effect of efficiency;Cultivate the professional talent team of sponge city,build the sponge city industry research platform,form the strong development of the sponge industry,and promote the construction of sponge city;Will all kinds of primary and secondary schools into the priority project implementation,to safety first,the function of both facilities and landscape requirements,combining engineering measures with non-engineering measures construction sponge campus,play an exemplary and leading role on campus;Accurate propaganda,promote the public participation,the formation of the co-construction and sponge city atmosphere,etc.,in order to sponge city construction and improve the central bar and even the whole country to provide scientific decision basis and suggestions can be used for reference.
