Evaluation And Planning Strategy Of Urban Road Landscape Resilience Under Climate Change

Climate change leads to frequent extreme climate and natural disasters on urban roads.With the strengthening of the national awareness of disaster prevention and reduction,road landscape,as one of the backbone of urban construction,has become a new topic of urban resilience research in order to ensure the safety of people’s lives and property in the rapid recovery after disasters.Based on the research on the vulnerability of urban roads and the construction of urban resilience under the background of climate change,this paper constructs the resilience evaluation system of urban road landscape under the background of climate change,and puts forward the strategy of improving the resilience of urban road landscape,in order to better and faster cope with and restore the urban road landscape when it is hit by disasters.The first chapter introduces the research background and significance of urban road landscape resilience under climate change.The second chapter defines the relevant concepts of urban road landscape toughness and the research progress at home and abroad,and clarifies the research content and innovation points of this paper.In Chapter 3,according to the characteristics of urban road landscape toughness under climate change,appropriate resilience evaluation indexes are selected,and an evaluation system suitable for urban road landscape toughness under climate change is constructed based on AHP hierarchical analysis model.It is concluded that safety is the most important factor in the resilience of urban road landscape in the context of climate change.The fourth chapter takes some roads in Xihu District,Gongshu District,Shangcheng District and other administrative districts west of Qiantang River in Hangzhou as examples.Based on network data,field research and Arc GIS spatial information data processing platform,various index data are obtained and scored.After calculation,the weight scores of each road are obtained to judge the toughness level of the sample roads.In Chapter 5,based on the proposed evaluation indexes and road examples,from the perspectives of safety,durability,resilience and adaptability,the improvement strategies for urban road landscape toughness under the background of climate change are proposed.The sixth chapter summarizes and looks forward to the evaluation system and planning strategy.
