摘　　要：目的了解2005年甘肃省改水降氟设施运行使用现状，为进一步完善管理机制和提高降氟工程效益提供依据。方法对甘肃省33个重点病区县已建成的改水降氟设施运行情况（基本正常、问歇使用、报废）和非正常运行原因进行调查。水氟测定采用氟离子选择电极法。结果共调查改水降氟工程993处，覆盖3389个病区村，改水工程类型以打井和引水为主；其中水氟合格且运行基本正常的工程仅682处，占68，68％（682／993），覆盖2174个村，占病区村的64．15％（2174／3389），实际受益人口116．56万人，有311处工程间歇使用或报废，而不能发挥防病作用，占31．32％（311／993），主要原因是超过使用年限、水源不足、水氟超标和管理不善。结论甘肃省大部分改水工程运行基本正常，但有近1／3的工程处于非正常运行状态，工程管理亟待改进和完善。Objective To evaluate the running status of the water-improving projects in Gansu Province in order to further improve the supervising mechanism and raise the efficiency of defluoridation in drinking water. Methods The water-improving projects, either being normal, or intermittent, or discarded and the cause of abnormal running in 33 counties in Gansu Province were surveyed with unified standard method. Fluoride content in water was determined by F-ion selective electrode. Results 993 water improving projects covering 3389 fluorosis villages were surveyed, 682 projects worked well [68.68%（682/993 ）] and had supplied water with normal fluoride contents to 2174 villages [ 64.15% （2174/3389 ） ] and benefited 116.56 hundred thousand populations. And the rest 311 [31.32%（311/993）] projects worked abnormally or supplied unqualified fluoride water. The main causes were the exceeded lasting life, insufficiency of water resources, high fluoride content in water and unqualified administration. Conclusions Most of the water-improving projects in Gansu Province are basically running normally, but about 1/3 of the projects do not function well, so the management of the projects must be improved and consummated.
