摘　　要：昌平小汤山镇北山地区土壤与水系沉积物的元素组成与燕山期岩浆岩、元古宙—中生代沉积岩具有良好的空间对应关系。受地质体、地形与河流的共同影响,平原地区土壤充分反映出成土母岩为北山岩石的地球化学性质。小汤山地区土壤与水体的氟含量明显高于其他地区,高氟环境对生态系统具有危害性,使得当地居民既往历史上长期流行地方性氟中毒疾病。因此,只有通过查明地质背景状况来制定环境降氟措施,才能有效提高人群健康质量。The element composition in soils and stream sediments in the Beishan area of Xiaotangshan town, Changping district, Beijing, has good spatial correspondence with nearby Yanshanian magmatism, and Proterozoic -Mesozoic sedimentary rocks. Affected by geological body, topography and stream, soil in the plain region fully reflects geochemical nature of soilforming parent rocks in the Beishan area. Fluorine content in the soils and waters in the Xiaotangshan area is obviously higher than that in other regions. High fluo- rine environment has harmfulness to ecosystem. Local residents suffer a long -term epidemic fluoride intoxication in history. Only by investigating geological background, the better arrangements for reducing fluorine in the environment can be established to effectively improve resident health qualities.
