摘  要：
以贵州省普定县喀斯特山地营造的5种不同类型人工林为研究对象,运用ICP–MS法测定不同类型林分土壤中6种微量元素(Fe、Mn、Cu、Zn、Co、Mo)含量,分析了土壤有效态微量元素含量与土壤有机质含量、pH之间的相关性。结果表明:(1)6种微量元素中Fe含量最高,Mo含量最低,其中有效态微量元素的表聚效应明显。(2)6种微量元素的活化率大小顺序为:Cu>Zn>Mo>Mn>Fe>Co;有效态Mo、Co含量均低于临界值;不同林分土壤微量元素有效性综合指数大小顺序为:刺槐林>桤木林>杜仲林>冰脆李林>滇柏林。(3)土壤有机质含量与有效态Zn含量呈显著负相关(p<0.05),与有效态Fe、Mn、Cu、Co、Mo含量呈正相关;土壤pH与有效态Fe、Mo含量呈显著负相关(p<0.05),与有效态Cu、Mn和Co含量呈负相关,与有效态Zn含量呈正相关。

摘  要：
Five different types of plantations were studied from Puding county of Guizhou province in Karst mountainous site.The contents of six soil microelements(Fe,Mn,Cu,Zn,Mo and Co) were analyzed by the equipment ICP-MS.In the meantime their relationships with soil organic matter and pH value were analyzed by the correlation analysis method.The results indicated that:(1) The highest and lowest contents of soil microelements were Fe and Mo respectively.The contents of soil available microelements showed surface accumulation effect.(2) There existed the regularities of Cu>Zn>Mo>Mn>Fe>Co rate of available to total contents and Cupressus duclouxiana stand > Robinia pseudoacacia stand > Eucommia ulmoides stand > Prunus salicina stand > Alnus cremastogyne stand for comprehensive microelement availability index in different types of plantations.(3) There was a significant negative correlation(p<0.05) between the contents of soil organic matter and Zn availabilities,but a positive correlation between the contents of soil organic matter and Fe,Mn,Cu,Co,and Mo availabilities.Soil pH value was highly and negatively correlated(p<0.05) with the contents of available Fe and Mo,negatively correlated with available Cu,Mn and Co contents,and positively correlated with available Zn contents.
