摘　　要：在中国北方地区,由于饮用高氟地下水而导致的地方病,严重影响了当地人民群众的身体健康。地下水中氟元素的富集是一个非常复杂的水文地球化学过程。本文在前人研究中国北方高氟水分布特征基础上,总结了高氟水形成的气候、水文、地质构造、岩性与土壤、水文地质条件和水化学特征,并结合项目成果提出高氟水地区适宜找水模式和一些去除水中氟元素有效的措施,从而避免氟中毒的发生。Fluoride poisoning by drinking high-fluoride water is a rather common phenomenon in the world, and groundwater with high fluoride is very widespread in northern China. As regional groundwater is the main source of water supply, fluoride poisoning has developed to such an extent that it has seriously affected human health. The enrichment of fluoride in the groundwater is a very complicated hydrogeochemical reaction. Results of the studies conducted in northern China are summarized in this paper. It is indicated that regional high fluoride-bearing groundwater on the whole exhibits some characteristics in distribution. The formation of high fluoride water was studied in relation to climate, hydrology, geological structure, rock and soil, geological and hydrological conditions of water chemistry and other natural factors. The groundwater exploration direction and some key points in the high-fluoride groundwater zone are pointed out on the basis of relevant results. Having analyzed the distribution and environmental characteristics of high fluoride -bearing groundwater, this paper advances many effective measures to reduce the fluoride content in drinking water and to cure the disease.
