在松嫩平原的外围,小兴安岭地区的岩石及含氟矿物为肇东市沉积地层中碎屑物的重要来源.为了研究土壤与氟中毒的关系,通过土壤中的氟分布、迁移转化规律的研究,发现肇东市土壤颗粒越细,比表面积越大,黏土质胶体含量越高,越有利于氟的富集,病情越重.在盐渍化发育地区,土壤溶液中的F-浓度相对较高,地下水中F-浓度也相对较高,氟中毒的病情相对较重.%At the periphery of the Songnen Plain,the rock and fluorine minerals of Xiaoxinganling Mountains area are the important source of clastic in sedimentary strata of Zhaodong.In order to study the relationship between soil and fluorosis,through the research of fluoride' s distribution in soil and migration and transformation law,it was found that the finer soil particles,the larger surface area.is and the higher content of clay colloid are beneficial to the enrichment of fluorine,and the illness is serious.The fluorinion concentration in soil solution and underground water are relatively higher,the fluoride poisoning is relatively heavy in salinization area.
