Research On Sponge Block Design Strategy Based On The Concept Of Low Impact Development (LID)

With the frequent occurrence of urban shackles,the theory and practice of sponge cities have received more and more attention.Low-impact development is an important part of sponge city construction,reflecting the protective development of the city and conforming to the connotation of sponge city.Therefore,the theoretical and practical research of sponge city is imperative.Due to the lack of systematic research at the block level,the article mainly attempts to build a sponge city system at the block level and proposes a strategy for building a sponge block.The first chapter mainly introduces the research background;the concept of low impact development,sponge city and sponge block.The purpose of the research and the significance of the research are introduced.Finally,the research methods and the framework of the thesis are introduced.The second chapter studies the theoretical basis of the sponge block;introduces the historical stage of the study of the sponge block at home and abroad;analyzes the principle of low impact development.A typical case study of the sponge zone in foreign countries was selected for analysis.The third chapter attempts to construct a low-impact development system suitable for the block level.The theoretical framework of the planning and construction of the sponge block is summarized from the aspects of development principles,low-impact development design goals,design content and design process.The fourth chapter mainly takes the four aspects of water space,urban architecture,green space landscape and road plaza in newly built blocks as the main elements,respectively expounds the corresponding low-impact development design strategies,and provides reference for the construction of the sponge block;From the aspects of building renewal,road upgrading and landscape upgrading,the application of low-impact development concept in the sponge block is expounded,which provides reference for the reconstruction of the old city of the sponge city,and enhances the operability of the sponge city construction at the block level.The fifth chapter supplements the case of the sponge block under the urban transformation,and combines the actual reconstruction project to illustrate the specific application of the sponge block in the old city reconstruction,and provides a case study for the sponge block in the old city reconstruction design.The seventh chapter summarizes the main research results for the sponge block and analyzes the shortcomings of the research results.
