| At the 18 th China Congress of the Communist Party of China,the construction of ecological civilization was established as an important part of the overall development of the "five in one" development.Subsequently,the construction of ecological civilization became the focus of the construction of the new era in China.So that urban waterlogging,urban haze and other urban problems has gradually become a hot discussion.To this end,in the professional research,seeking to solve the problem of urban strategy is gradually becoming the focus of various disciplines.In this paper,Jinan City was elected as the first batch of sponge city pilot cities as the background,the introduction of urban issues to improve the sponge city construction theory.Based on the study of sponge city theory and the planning and publicity of Jinan City as a pilot city of sponge city,it is concluded that the current planning and construction of sponge city in Jinan is mainly concentrated in municipal facilities,urban greening and urban roads.A larger proportion of urban residential construction types,construction scale is small,and the development of small efforts.However,Jinan City,both residential surroundings or internal,often complex situation,frequent waterlogging disasters and in the event of waterlogging on the lives of residents and the impact of personal safety is also the most serious.In view of the large size of existing settlements,the status quo is responsible,and the Jinan City area of the terrain is quite different,so in accordance with the conventional low-impact development of existing residential areas to carry out low-impact development results are not obvious,therefore,for Jinan City It is necessary and urgent to study the characteristics of the existing residential areas and carry out low-impact development strategies.First of all,the paper analyzes the causes of waterlogging problems in Jinan city and the distribution of common waterlogging and waterlogging points in Jinan City,which is the main urban problem of Jinan City,which is the starting point of the urban waterlogging The status quo of urban areas have a greater impact on the city caused by waterlogging disasters;therefore,the author of the city within the common waterlogging points around the existing residential area for the research object,through on-site research and interviews with residents,summed up the existing residential area of Jinan And analyzes the current government policy guidance,the government construction experience,the residents’ willingness to transform and so on,and obtains the realistic feasibility of the low impact development of the existing residential area.Secondly,on the basis of feasibility,the paper takes the special plan of sponge city in Jinan(2016-2030)as the basic frame,taking the unique terrain and terrain of Jinan City,the present situation of urban architecture,the distribution of common water points,the construction of eco-city And other factors for the zoning factor,the main urban area of Jinan to carry out the appropriate low-impact development zoning;and further to each district on the basis of low-impact development principles,for the existing settlements of green landscapes,residential roads,residential buildings The development of the focus of the selection and construction of the intensity classification,which formed from the city of Jinan city level to the existing residential area of the low impact of the development strategy,and in the "division grading" strategy under the guidance of the low impact of the development of technical measures And implementation principles.Thirdly,under the guidance of the low-impact development strategy,the basic characteristics of the existing residential area in Jinan City are summarized as "the main","To save the main","to stagnation" of the three mainly applicable to the existing residential area of the low impact of the development of technical units,and each unit for the specific basis for the construction of structural analysis,in order to better To achieve low-impact development of technical measures in the whole area of the synergistic effect,summed up the "tandem,parallel,mixed" three technical measures of the combination of ways to systematically on the existing residential areas to implement low-impact development and construction.Finally,on the basis of summarizing the whole article,this paper puts forward the construction principles and precautions in the construction of new sponge type and ecological residential area,so as to provide a more suitable for the construction of sponge city in Jinan City and the future,More detailed residential development and construction strategies. |
