| 摘 要： | 土壤中氟是人体必需元素,但过量的氟摄入影响人体健康。本研究以湖北省荆州地区为例,通过该地区典型利用方式和土壤类型共177个代表性样点取样分析,摸清了该地区农业土壤水溶性氟含量状况,探讨了土壤基本理化性质与土壤水溶性氟含量的关系。结果表明,该区域土壤水溶性氟在0.22 mg/kg~4.57 mg/kg之间,平均值为1.74 mg/kg,变异系数高达50%。潮土中水溶性氟含量最高(1.86 mg/kg),其次是水稻土(1.76 mg/kg),棕红壤(0.55 mg/kg)水溶性氟含量最低。土壤水溶性氟含量在pH值低于7.5时与土壤pH值呈极显著正相关关系。旱地与草地土壤的水溶性氟含量随着有机质的增加而显著增加,但水稻土有机质含量与土壤水溶性氟含量无明显相关性,表明研究区内土壤高氟含量的形成与当地的母质主要为冲积母质有直接关系。

| Abstract: | Fluorine is one of the necessary elements to human being,while excessive uptake of the fluorine would have impact on human being health.In this study,177 typical agricultural soil samples from Jinzhou City,Hubei Province were analyzed to figure out the distribution characteristics of water-soluble fluorine content in agricultural soil in this area.Results showed that the water-soluble fluorine content varied from 0.22 mg/kg to 4.57 mg/kg among various districts,with average about 1.74 mg/kg with a variation... |
