改水降氟是预防、控制和消灭饮水型氟中毒的根本措施,而且效果显著。但因改水工程浩繁,耗资数额较大,国家财力不足,所以步履维艰,进展速度一直不够乐观。就目前客观形势而言,改水降氟任务不仅艰巨而又非常紧迫,刻不容缓。为加快其发展步伐,扩大经费来源,采取多渠道、多层次筹资办法,使经费来源由原来只靠国家补助的单一化转变为国家、集体、个人齐筹集的多元化,很有必要。
Fluoride reduction by water is a fundamental measure for the prevention, control, and elimination of drinking-water-borne fluorosis, and it has a significant effect. However, due to the voluminous water-construction projects, the large amount of capital spent and the lack of state financial resources, they are struggling and the progress has not been optimistic enough. As far as the current objective situation is concerned, the task of improving water and reducing fluoride is not only arduous but also very urgent, and it is imperative. In order to accelerate the pace of its development, expand funding sources, and adopt multi-channel and multi-level financing methods, it is necessary to change the source of funding from the original single state subsidies to the diversification raised by the state, collectives, and individuals.
