摘　　要：通过土壤水溶性氟与土壤基本性质的相关分析及室内氟污染的模拟试验,对土壤水溶性氟含量及其影响因素作了初步研究。结果表明,土壤水溶性氟与土壤pH值和土壤有机质含量均呈极显著正相关。土壤水溶性氟与土壤中<0 01mm土粒含量呈显著负相关。水溶性氟与全氟无一定的相关性。不同土壤间水溶性氟的含量为:石灰土明显高于黄壤、紫色土和红壤,后三者间差异不大。供试的3种土壤经室内模拟培养后,水溶性氟在各处理间呈相同的变化趋势,硅钙肥、风化煤和石灰、粉煤灰均有使土壤水溶性氟增加的作用。但施用风化煤和粉煤灰相对较安全。The relevant analysis between watersoluble fluorine content in soils and the simulated experiment of fluorine pollution indoor are carride out.The result shows that watersoluble fluorine has a positive correlation with pHvalue and organic matter,both have a level of extremely significance.Watersoluble fluorine has a negative correlation with the amount of <001mm particle, and has a level of significance.Watersoluble fluorine has no direct correlation with total fluorine.The watersoluble fluorine amount in calcareous soil is obviously higher than those in yellow soil, purple soil and red soil, the three later have no clear difference.After the three soils have been cultivated indoor, watersoluble fluorine and fluorine adsorption have the same inclination among treatments.SiCa fertilizer, weathered coal, lime and coal dust all show an effect on increasing the watersoluble fluorine in soils but the weathered coal and coal dust are relatively security when using.
