Urban-Rural Response Mechanism and Construction Strategies in the Face of Cascading Effects of Typhoon Disasters:Research Based on Hongqiao,Yueqing
The"cascading effect"of typhoons,characterized by a chain of disaster events,multi-factor interactions,and the cumulative amplification of damage,poses significant challenges to urban and rural environments in affected regions,making risk-reduction and resilience-enhancing construction practices critical goals in human settlements development.Following a technical pathway of"Response Mechanism-Catastrophe Mechanism-Construction Strategy",the paper examines the cascading pro-cess of"Typhoon—Rain,Flood,Surge—Waterlogging"in Hongqiao Basin Township Cluster,Yueqing City.Based on an analysis of the cascading process driven by fac-tors in three aspects:the marine-terrestrial interface,watershed characteristics,and urban-rural space,the paper points out the critical importance of process control in local governance.Consequently,it introduces the concept of the urban-rural environ-mental construction unit,a spatial unit suitable for development and disaster manage-ment with integrated hydrology,geomorphology,and demand considerations.The pa-per sheds light on the urban-rural response mechanism to the cascading effect of ty-phon disasters.Furthermore,by comprehending the nonlinear catastrophe effects,it helps develop strategies for sustainable urban-rural development in typhoon-prone ar-eas.
