摘　　要：结合桂林市"十二五"规划,对桂林市2015、2020年河道外需水量进行了分析计算。结果表明,需水量呈波动上升趋势,2015年末将达到44.42×108m3,2020年末将达43.73×108m3,均超过各设区市2015、2020年用水总量的控制目标43.71×108m3[1]。而需水量控制主要集中在灌溉水利用系数、工业水重复利用率、节水器具普及率的提高及城市供水管网漏失率的降低,并据此提出了桂林市河道外用水总量控制的相关对策。Water requirements of Guilin outside the watercourse is calculated and analyzed for 2015 and 2020,which coupling with “12th five-year plan of Guilin City”.The calculation results show that water requirements of Guilin outside the watercourse is increased wavelike,at the end of 2015 it will reach 44.4 ×108 m3 , and 43.73 ×108 m3 end of 2020.Obviously,they all exceed the water utili-zation total control target 43.71 ×108 m3.In order to control water requirements,we should improve the water efficiency of irrigation, water reuse rate, water-saving appliances penetration and reduce the leakage rate of city water supply network.Hereby,it is crucial to promote suggestions and meas-ures for water requirements in Guilin outside the watercourse.
