Research on strategies of low-impact urban design in China. Take Beijing waterfront urban design evaluation as an example

This paper aims to provide theoretical method support and practical experience for creating environment friendly urban space by low-impact urban design methods, and discussed on two aspects of theory and practice. Firstly, the definition of low-impact urban design in the context of Chinese cities is expounded by combing the development stage of urban design environment view and analysing the development needs of Chinese cities. Then, it discusses the framework content and evolution process of low-impact urban design in China, and puts forward the view that low-impact development elements and low-impact design control elements are mutually dependent and mutually reinforcing. Next, the objects and related characteristics of low-impact urban design are explained from multiple perspectives, as object system, object composition and basic characteristics. Relevant strategy formulation is the focus of this paper. First, it is necessary to establish a low-impact urban design system in coordination with legal planning, so as to help implement the low-impact design concept with the seriousness and execution of legal planning. Secondly, the framework of low-impact urban design control elements including 5 different layers is established, which can effectively evaluate and optimize the impact of design results on the city. Thirdly, the value evaluation mechanism of dynamic cycle is proposed, which is helpful to the implementation of low-impact urban design and the restoration of design intention. Finally, the paper takes Beijing waterfront urban design evaluation as an example to apply the low impact evaluation model proposed in this paper, and satisfactory results were obtained
