摘要
总结了历史上８００多年漓江洪涝灾害情况和１９３６～１９９８年６０多年有观测的记录资料，认为漓江洪涝灾害加剧的原因主要是上游水源林的破坏和对青狮潭水库调洪管理不尽科学；而枯季缺水，既有降雨量时空分布不均自然因素的原因，也有过量索取漓江水、上游水源林破坏、漓江补水工程的副作用、水资源浪费等人为的影响，而且以人为因素为主。要解决漓江洪涝灾害及枯季缺水，在技术措施方面，应改变现行的桂林城市供水方案，即供水由漓江改用青狮潭水库，并在漓江上游修建川江和斧子口水库，实施生物工程等；在政府行为措施方面，宜尽快建立漓江流域资源和环境的管理机构，实行统一领导、统一规划、统一管理、严加保护、合理开发。通过这些措施的实施，可基本消除漓江洪涝灾害而达百年一遇，漓江枯季水量也可望达４０～５０ｍ３／ｓ，从而基本解决枯季缺水问题。
After summaries of flood disasters along Li River for more than 800 years and their observed records for 60 years from 1936 to 1998, it is thought that floodwater and waterlogging calamities have been intensified by the destruction of upstream woods and not very scientific administration of flood regulation of Qingshitan reservoir, and the water deficiency during dry seasons is caused not only by natural factors, e.g., uneven distribution of precipitation in time and space, but also by artificial factors, i.e., excessive use of Li River water, destruction of upstream woods, byeffect of the project supplying water for Li River and waste of water resources, etc.. Therefore, to resolve the mentioned above problems, technologically, current water supply of Guilin by using Li River water should be replaced by using Qingshitan reservoir water, and two reservoirs, Chuanjiang reservoir and Fuzikou reservoir, should be built in the upstream of Li River. For local government, a special administration of resources and environment along Li River catchment should be established as quickly as possible so as to exert unified leadership, unified plan, unified management, effective protection and reasonable development. The implementation of the mentioned above measures may basically eliminate the flood disasters along Li River, and the flow of Li River in dry seasons may be up to 40～50 m 3/s .
