长江经济带城市排水系统韧性时空分异特征及其驱动机理
Spatio-Temporal Differentiation Characteristics and Driving Mechanism of Urban Drainage System Resilience in the Yangtze River Economic Belt
摘要
Abstract
Drainage system resilience refers to the ability of resistance,adaptation and recovery of a drainage system in response to external shocks,and enhancing drainage system resilience is crucial for urban safety.Ac-cordingly,based on examination of 126 cities along the Yangtze River Economic Belt,including prefecture-level cities,autonomous prefectures and higher-level cities,the resilience level of drainage systems and its spatio-temporal differentiation characteristics from 2003 to 2023 are comprehensively analyzed based on a"Resistance-Recovery-Adaptation"framework,and the driving mechanism behind the spatio-temporal differentiation of drain-age system resilience is investigated by using geographic detectors.The results are as follows:①the resilience of drainage systems in the Yangtze River Economic Belt presents a temporal characteristic of"overall stability with local fluctuations."Spatially,it has evolved from an initial pattern of"higher in the east and lower in the west"to a new pattern of"increasing in the west while decreasing in the east"with regional disparities narrowing.②re-sistance,adaptation and recovery are heterogeneous in spatial changes.③the driving mechanism behind the spatio-temporal differentiation of urban drainage system resilience in the Yangtze River Economic Belt is mani-fested in economic-technological synergy,social-natural dynamic balance,and natural-technological complemen-tary substitution.关键词
