摘要
用主成分软件分析昆明西山植物微量元素含量特征,元素Mn、Ph、Ni含量的累计贡献率达84%,从而建立了以Mn、Ph、Ni为主导的三个主成分方程。
Character of trace elements on plants from Westem hill of Kunndng was studied by principal component analysis. In the analysis, computer sofiware is utilized. Accumulation contribution raio of content of Mn, Pb ,Ni has reached 84%. Then Mn, Pb, Ni play a leading mle in principal componentequations. Three equations are established.
