| 摘 要： | 天山山地土壤中微量元素含量是比较丰富的。全量含量大多超过我国和世界土壤平均含量。有效态元素含量差异较大,但多数元素含量都超过已知临界值。在分布规律上全量元素垂直差异较明显,但水平上差异不明显,有效态元素的分布某些元素与有机质含量成正相关和全量元素之间无明显的相关性。锶元素在土壤的垂直分布中比较特殊。在动植物体中的生理作用尚需继续深入研究。山地土壤中除锰、锌的有效态含量在剖面中受有机质影响使上下层变化较大之外,其它元素则与母质相似,但土壤类型、质地、pH以及氧化还原电位等因素的影响也是不可忽视的。

| Abstract: | The Tianshan Mts. lie across Junggar and Tarim basins, spanning 1700 km from the west to the east. The main soils on the iaountain lands include mountain chernozem(1100-1700 m), mountain gray cinnamon forest soil(1700-2800 m), subalpine meadow soil(2800-3000 m) and alpine meadow soil(3000-3500 m). The contents of total and available Mn, Zn, Cr, Ni, Co, Cu and Sr in the soils were deterrnined.The results showed that the total contents of all the trace elements determined were more than the mean values of soils in China and of the world. The available contents were mostly more than the critical values.The contents of total trace elements except Sr tended increased with the increase of elevation on which the soil was located, but no horizontal variation was found. Sr content in soil and plant was higher. The distribution of the crate element was mainly related with parent matcrials and organic matter content of the soils. |
