目的了解河南省降氟改水工程运行现状,探索改水工程的高效管理模式。方法采取以县为单位整群抽样,对安阳、濮阳、焦作3个市的安阳县、清丰县、武陟县3个县的降氟改水工程全部进行调查。结果共调查442处降氟改水工程,其中正常使用工程327处,占73.98%,间断供水工程20处,占4.52%,停用及报废工程95处,占21.50%。3个县的降氟改水工程中,行政村管理模式、个人承包管理模式和商业化管理模式的正常运行率分别为71.69%、60.50%和92.79%,差异有显著性(P<0.01)。结论商业化管理模式的降氟改水工程发挥的效益最高,经济条件许可的地区应倡导这种管理模式。
Objective To understand the operation status of fluoride reduction and water diversion project in Henan Province and to explore the efficient management mode of water diversion project. Methods A cluster sampling was carried out on a county-by-county basis. All the fluoride-lowering and water-diversion projects in Anyang, Qingfeng and Wudai counties in Anyang, Puyang and Jiaozuo were surveyed. Results A total of 442 fluoride reduction and water diversion projects were investigated, of which 327 were normal use projects, accounting for 73.98%, 20 were discontinuous water supply projects, accounting for 4.52% and 95 were disabled or scrapped, accounting for 21.50%. In the three counties, the normal operating rates of the administrative village management mode, individual contract management mode and commercial management mode were 71.69%, 60.50% and 92.79% respectively, with a significant difference (P <0.01). Conclusion The commercialization of the project of fluoride reduction and water diversion has the highest benefit and the region should license such management mode.
