摘　　要：为提升城市污水系统适应气候变化能力,采用层次分析法,从脆弱度和准备度两个维度,以及雨水调蓄适应能力、管网适应能力、污水处理适应能力和经济适应能力等角度构建了北部湾沿海城市污水系统气候变化适应性评估体系模型,对北海、钦州、防城港、湛江市城市污水系统气候变化适应性进行了评估。结果表明,钦州城市污水系统气候变化适应性较好,北海、防城港、湛江城市污水系统气候变化适应性一般。湛江应重点加强雨水调蓄能力和管网适应能力建设,防城港应加强污水处理适应能力建设,北海应加强污水管网能力建设。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.
