摘　　要：目的全面了解辽宁省防氟改水工程运行现状和存在的问题,及其对地氟病流行趋势的影响。方法对辽宁省地氟病区2003年以前修建的改水降氟工程运行与管理现状逐项调查。结果经历了20多年,辽宁省修建的1193处改水降氟工程,已有622处因破损、报废而停止供水,占工程总数的52.14%,56万病区居民再次受到高氟水的危害;由于干旱、过量用水使地下水位下降,或供水管网破损等原因,有10.1%的工程供水范围缩小;还有5.4%的工程在向病区居民供高氟水,全省仅有29.8%的改水降氟工程保持正常供水。结论辽宁省降氟工程运行现状令人十分担忧,重饮高氟水将使病区群众返病、返贫。Objective To find out present state of water-improving project and its influence on endemic fluorosis in the province, Methods The running status and management of all water-improving project built before 2003 were individually investigated, Results Among 1193 water-improving projects which had worked for more than 2 decades in whole province, 622 projects were worn out or discarded as useless, accounting for 52.14 % and 560 thousands people was endangered by endemic fluorosis again. The supplying area was reduced due to aridity, excessive use of under ground water and the damage of the water pipeline, accounting for 10.1%. Additionally, 5.4% projects offered water containing excessive fluorine. In the whole province, only 29.8% water-improving projects worked normally. Conclusion We are apprehensive of the present state of water-improving projects, considering that re-use of high-fluorine water will lead local people returning to endemic fluorosis and poverty.
