Abstract
Taking the water supply sources plan of Nanning,Qinzhou and Fangchenggang city agglomeration in Bei-bu Gulf as example,the idea and method of determining the water sources plan for urban agglomeration on large spa-tial scale.On the basis of comprehensively sorting out the water sources around the Nanning,Qinzhou and Fangchenggang city agglomeration,the authors analyzed the water supply potential of surface,underground and un-conventional water sources,and calculate the water supply capacity of the water source projects which have been built,are under construction or newly built.According to the water demand forecast results of each city and the wa-ter supply capacity of surrounding built water source projects,the author analyzed the water supply gap in each city's planning level year,initially drafted separate water supply source schemes for each city,and proposed water source options for each city based on preliminary comparison.Based on the water resource allocation scheme with joint scheduling of different reservoir groups,the author sorted out the water supply plans from reservoir groups to city agglomeration,and determined the water supply sources plan for city agglomeration after technical and econom-ic comparison in respects of water supply reliability,engineering geological conditions,environmental factors,land requisition and resettlement,project benefits,operation cost and investment.关键词
