摘要
分析了祁连山中部冰缘区16种高山植物9种必需元素含量。结果表明,研究区域内的植物与一般的陆生植物相比大量富集Ca和Fe,但是K,Mg,Cu含量小于陆生植物元素含量平均值,而Na、P、Mn、Zn与陆生植物元素含量平均值相当,这与土壤中相应元素的含量关系不大,主要是植物生命活动过程中主动吸收的。
The content of 9 essential elements of 16 species periglacial plant in in middle region of Qilian mountain was analyzed. The results show that the content of Ca, Fe in periglacial plants is much higher than common terrestrial plants content; but K, Mg, Cu content in periglacial plants is lower higher than common terrestrial plants content; other 4 elements Na, P, Mn, Zn content is normal. The correlation analysis shows that essential element accumulation in periglacial plants is not significantly related with elements contents in soil .
