Research On The Design Of The Old City Sponge Transformation Based On The Concept Of LID

During the transition period of urban construction in China,the economic and social development has entered a new normal,and the construction of ecological civilization has gradually become an important part of national strategy.In this context,sponge city is not only an inevitable choice to effectively promote the transformation of urban living environment in China,but also a practical measure to respond to the country's efforts to strengthen ecological civilization construction.In recent years,as a major project to strengthen urban planning and construction management and alleviate urban waterlogging,the construction of sponge city has been carried out in many cities throughout the country.In the case of the complex old city,the difficulty of sponge transformation has increased,but it is still an important part.This study hope that through the literature study method,inductive deductive method and model analysis method,example method and other research methods,will the old way of green development and way of life to become "faithful",let the old city reform from sponge is more theoretical and practical.Through relevant research,we can solve the problem of flood and flood in old city,and play an important role in the past and future.In this paper,the results and shortcomings of the current management of low impact development and old city rain flood are analyzed and analyzed.Through the investigation and summary of the investigation and summarization of the large amount of data,we can find out the difficulties of the sponge transformation in the old city and the feasibility of LID technology in the old city sponge transformation in China.From the macro spatial pattern analysis and micro engineering measures on the two levels of different types of land reform from sponge principles,strategies and methods,make the buildings in the old city into district,city road,green square,the city water system the four regional flexible for all kinds of rain flood problem effectively take different measures.In this paper,the feasibility of the reconstruction is verified by the sponge city reconstruction project in the core area of the county town of the hui autonomous county of langfang city,with a view to providing reference for similar projects.
