柳州生态市建设需水量研究

结合柳州生态市建设规划,对柳州生态市建设需水量进行计算和分析。结果表明：柳州生态市建设需水量呈波动上升趋势,生态市建设期末将达到100.32×108 m3,水资源开发利用程度为0.406,其中市区、柳江和融安的水资源开发利用程度分别为1.529、0.425和0.410,水资源处于过度开发状态;生态市建设需水量主要集中在林地生态需水量、农业需水量和工业需水量,因此在生态市建设中需加强这三方面的节水工作;居民生活需水量和绿地生态需水量较小,但增幅较大。据此,提出了柳州生态市建设水资源保护与开发利用的相关对策。

Water Requirements of Liuzhou Ecological City Construction

Water requirements of Liuzhou ecological city construction are calculated and analyzed,for the eco-city planning of Liuzhou.The results show that water requirements of Liuzhou ecological city construction is increased wavelike,and the water requirements of final ecological city construction will reach 100.32×108 m3.Development and utilization level of water resources will be 0.406.Among the urban counties,Liujiang and Rong＇an counties are 1.529,0.425 and 0.410 respectively.The water resource is in an over-exploited condition,while the water requirement is mainly concentrated in forestland water requirement,agricultural water requirement and industrial water requirement.Therefore,it is vital for water-saving in these three aspects.The water consumption for residents and green space are relatively low,but the amplitude of increase is high.Hereby,it is crucial to promote suggestions and measures for water resource conservation and utilization in Liuzhou ecological city construction.
