| 摘 要： | 通过对碳酸盐岩与土壤、碳酸盐岩与红背山麻杆、裸花紫珠及土壤与红背山麻杆、裸花紫珠间的元素相关分析,发现:(1)碳酸盐岩和土壤的元素存在高度的相关关系,从岩石到土壤,元素迁移顺序总体表现为:CaOMgONa2OP2O5MnOPbZrFe2O3TiO2SiO2Al2O3;(2)土壤与两种检测植物的元素也存在较高的相关性,并且两种检测植物还表现出基本相似的土壤元素生物吸收系数,即:红背山麻杆的土壤元素生物吸收系数顺序为:PCaFeKNaMnPbAlMgZrTiSiO2,裸花紫珠的为:PKFeNaCaMnAlPbMgZrTiSiO2;(3)植物中的常量元素由岩石中的常量元素所决定,在同样的岩性基底上,不同植物体内富集、累积而成的元素结构有着较高的一致性。 |

| Abstract: | Through the analysis on the elements relationship and element removal between carbonate rocks and the soil,between carbonate rocks and vegetation（Alchornea trewioides and Callicarpa nudiflora Hook et Arn）,and between soil and vegetation（Alchornea trewioides and Callicarpa nudiflora Hook et Arn）.The study finds that,1） there is a high correlativity between the rock and soil with the general removal sequence as CaOMgONa2OP2O5MnOPbZrFe2O3TiO2SiO2Al2O3 from the rock to the soil;2） there is also a high correlativity between the soil and the 2 species of tested plant,and the plants get similar element absorption coefficient from the soil,with the sequence of element absorption coefficient of the Alchornea trewioides being PCaFeKNaMnPbAlMgZrTiSiO2,and that of theCallicarpa nudiflora Hook et Arn being PKFeNaCaMnAlPbMgZrTiSiO2;Element migration follow certain rules.That is,rock elements are high correlated with soil elements.From rock to soil,the general element migration sequence is CaOMgONa2OP2O5MnOPbZrFe2O3TiO2SiO2Al2O3.3） the macroelement in plants are determined by the rock,so there is higher correlativity and consistency in the elemental composition of the plant growing under the same lithology. |
