Abstract
Natural disasters and extreme abnormal weather caused by global climate change challenge the sustainability and stability of urban system. Urban river and lake system is an important ecological background of urban environment. Improving the ecological resilience of urban water system plays an important role in consolidating the stability of urban system. In view of the above problems, using the methods of literature research, case analysis and comprehensive analysis, this paper summarizes the theoretical research and practical experience of coping with global climate change and improving urban water system at home and abroad, and analyzes the challenges faced by China’s urban water environment under climate change. From the perspective of ecological restoration, this paper attempts to build the evaluation index system of water ecological restoration and the urban design technology system guided by water environment, and puts forward urban design strategies from three urban design dimensions: macro (urban agglomeration or region and its basin), meso (city and its basin) and micro (block and its basin), and explores the implementation of urban water system planning and design based on the concept of ecological restoration This is the way.
