采用单道扫描等离子体发射光谱仪(ICP)和微波消解仪测定了新疆沙冬青和蒙古沙冬青两种珍稀植物的叶片及生境土壤环境中15种无机元素(Al、B、Ca、Cu、Fe、Mg、Mn、Na、Ba、La、Co、Ni、Pb、Rb和Ti)的含量,其中两种沙冬青叶片及生境土壤中含量最大的元素均为Ca,最小的均为Co.应用两个独立样本检验(Independent-samples T Test)中的曼-惠特尼U检验法(Mann-Whitney U)分析15种无机元素的差异性,结果显示,两种沙冬青的土壤环境相似;叶片的无机元素除了5种元素(B、Fe、Co、Ni和Ti)呈现显著性差异以外,其余元素含量差异不显著;通过比较叶片和土壤的元素含量发现,15种元素均呈现显著性差异;通过叶片内无机元素的浓度与生境土壤中该元素浓度的比值比较,发现Pb和Ti两种元素的叶片内浓度与生境土壤中浓度比值存在显著差异.图1表7参25

The contents of 15 mineral elements (Al, B, Ca, Cu, Fe, Mg, Mn, Na, Ba, La, Co, Ni, Pb, Rb, Ti) in habitat soil and leaves of Ammopiptanthus nanus and A. mongolicus were detected by ICP and Milestone Ethos Touch Control. The maximum of the 15 elements contents both in the leaves and soil was Ca, and the minimum was Co. The differences in mineral elements between A. nanus and A. mongolicus were examined by Mann-Whitney U of independent-samples T test. The results showed that as for the element contents in the soil, there was no significant difference between these two populations; as for the element contents in the plants, there was no significant difference between the two plants except B, Fe, Co, Ni and Ti; as for the element contents between the soil and plants, there was significant difference; and as for the specific value of element contents in the soil and leaves of A. nanus and A. mongolicus, there was no significant difference between them, except Pb and Ti.
