| 摘 要： | 为了对河北献县土壤改良及对地氟病的防治提供指导性建议,采用地理信息系统与地统计相结合的方法对研究区表层土壤全氟的空间变异特征进行了分析。结果表明:献县表层土壤全氟经对数转换后符合指数模型,全氟具有很强的空间相关性,说明其有明显的可迁性特点,受水文地质、地形等自然结构性因素影响较大而受人为因素影响较小;用Kriging内插法对未测区域全氟进行最优估计,并形成插值图,可更直观的反映出研究区内表层土壤全氟的空间变异特征。从整体上看献县表层土壤全氟含量呈现东南西三部含量高而北部偏低的分布特征,其分布特征受河流走向影响较大且远离河床处氟含量呈渐增趋势。

| Abstract: | The objective of this paper was to offer suggestions for the soil improvement and prevent the soil fluorine disease in Xianxian Country.Spatial variability of top soil total fluorine in this area was studied by using GIS technique and geostatistical analysis.The results showed that the semivariograms for logarithm conversion value of total fluorine from Xianxian were fitted by exponential model.Total fluorine had strong spatial relativity and significantly moved characteristics.The spatial variability of to... |
