摘要
根据漓江流域内降雨时空分布的情况,分析了桂林水文站50多年的资料,得出:漓江多年平均径流量、年最小径流量、多年平均最小流量、年最小流量,均属正常变化范围。枯季水量没有逐年减少趋势或断流的可能。但河流的含沙量增加了,河床有逐渐增高趋势。漓江水质目前尚属Ⅱ类,但枯季某个时段氨氮、溶解氧有超标现象。为珍惜水资源,保护水环境,提出了保护漓江的建议性对策。
According to the Lijiang river basin's rain distribution condition in time and space ,the author analysed more than fifty years materal of Guilin hydrology. They concluded that normal annual flow, annual minimum flow ,minimum annual discharge and annual minimum discharge of the Lijiang river basin are in normal varying scope . There is no drought season discharge decrease tendency year by year or cutting off possibility. But sediment content of the river increases ,the river bed has a raising tendency.Now water quality standard of the Lijiang river is the second kind, but sometimes NH3-NH4+ and DO exceed standard in drought season.In order to value water resources and protect water environment, the anthors also propose countermeasure of protecting the Lijiang river .
