以辽西阜新县建设镇为研究区域,采用传统统计学和地统计学相结合的方法,对该区域内耕地中微量元素的含量和空间变异特征以及克立格空间插值进行研究,结果表明:土壤中Zn元素变异系数最大,为70%,Ca和Cu居中,变异系数分别为58.81%和56.36%,Mn变异系数最小,为10.78%;高程与土壤各养分均呈负相关性,其中Mg、Fe和Mn、Zn、Cu元素分别与高程表现为显著和极显著的负相关;除Zn以外,其余各元素的块金值与基台值之比皆小于0.25,分别表现为中等空间相关性和高度空间相关性;插值结果表明,Cu在东南部富集,Zn由东北向西南呈现明显的阶梯变化趋势,其它个元素空间差异不大。
Taking the construction town of Fuxin County in western Liaoning as the research area, the content of trace elements in soil and spatial variation characteristics of Kriging and the Kriging space interpolation were studied by the combination of traditional statistics and geo-statistics. The results showed that soil The coefficient of variation of Zn was the largest, 70%, Ca and Cu were middle, the coefficient of variation was 58.81% and 56.36% respectively, and the coefficient of variation of Mn was the lowest, which was 10.78%. Elevation and nutrient of soil were negatively correlated, And Mn, Zn and Cu were significantly and significantly negatively correlated with elevation, respectively. The ratios of nugget value to abutment value of all the elements except Zn were all less than 0.25, showing medium-spatial correlation and height Interpolation results show that Cu is enriched in the southeast, Zn shows obvious stepwise trend from northeast to southwest, and the other elements have little difference in space.
