摘　　要：本研究以云南圭山山脉地区的弥勒县、泸西县、石林县(以昆明市作为对照)土壤及饲用植物为对象,分析主要矿物元素在土壤和饲用植物中的组成及质量分数,探讨该地区主要矿物元素在土壤及饲用植物中的分布规律。结果表明,与昆明地区相比,云南圭山山脉地区土壤中含有较高的锶、钾、镁、钼和氟元素,而磷、铁、锌、铜与钴元素质量分数较低;同时饲用植物中含有较高的锶、镁、铁、锌、铜、锰元素,而磷元素质量分数较低;磷、钙、镁与锶元素质量分数在土壤与饲用植物间存在显著的正相关,表明该地区饲用植物中钙、磷、锶与镁元素较多来自土壤中。The soil and forage plants in different locations of Yunnan Guishan mountain area （including Mile,Luxi and Shilin County） were selected to analyze the composition and mass fraction of major mineral elements in this study.Distribution characteristics of mineral elements in soil and forage plants were systematically studied.The results showed that the mass fractions of strontium,potassium,magnesium,molybdenum and fluorine elements were higher,and the mass fractions of phosphorus,iron,zinc,copper and cobalt elements were lower in the soils of Yunnan Guishan mountain area than in that of Kunming area.On the other hand,the mass fractions of strontium,magnesium,iron,zinc,copper,manganese elements were higher,and the mass fraction of phosphorus element was lower in the forage plants of Yunnan Guishan mountain area than in that of Kunming area.There was a significantly positive linear correlation between the soil and forage plants for the mass fractions of phosphorus,calcium,magnesium and strontium element.This indicates that calcium,phosphorus,magnesium and strontium element in forage plant mostly come from the soils in this region.
