Study on Evaluation of Climate Change Adaptability of Coastal Urban Sewage System in Beibu Gulf
In order to enhance the adaptability of urban sewage systems to climate changes,the analytic hierarchy process(AHP)was applied to construct a climate change adaptability assessment system model for coastal urban sewage systems in the Beibu Gulf from the perspectives of vulnerability and preparedness,as well as rainwater storage adaptability,pipeline adaptability,sewage treatment adaptability,and economic adaptability.The climate change adaptability of urban sewage systems in Beihai,Qinzhou,Fangchenggang,and Zhanjiang was evaluated.The results showed that Qinzhou municipal sewage system had a good adaptability to climate changes,while Beihai,Fangchenggang and Zhanjiang urban sewage system had a general adaptability to climate changes.Zhanjiang should focus on strengthening the capacity of rainwater storage and pipe network adaptation,Fangchenggang should strengthen the capacity of sewage treatment adaptation,and Beihai should strengthen the capacity of sewage pipe network construction.
