土壤微量元素的含量与分布特征是反映特定地区环境状况的一个重要因素,对土地资源的合理开发和利用具有重要意义.本研究以天山北坡三工河流域冲积平原型绿洲为研究区,选择盐土、潮土和灰漠土3种土壤类型,分析其B、Mn、Zn、Fe、Cu等微量元素的有效含量特征.结果表明:⑴以"全国农业系统的土壤速效微量元素丰缺指标"为标准,土壤有效Mn含量属于极低水平,有效Zn和Fe含量属于中等水平,有效Cu属于丰富水平,有效B属于极富水平;⑵三工河流域绿洲土壤中有效Mn、Zn、Fe、Cu含量与土壤pH呈负相关关系;土壤有机质对有效Fe、Cu含量影响很大;有机质和Mn的关系不明显,这和湿润地区研究结果存在显著差异;⑶不同的土壤类型对于土壤有效B、Zn和Fe的含量影响显著;潮土中微量元素的有效含量与盐土、灰漠土中含量相比有显著差异.

Taking the alluvial plain oasis as a study case, the available contents of B, Mn, Zn, Fe, and Cu in three soil types were analyzed with SPSS. The results showed that:①According to "Plentiful-lack index of soil available trace elements in Agricultural Libraries all over China", available Mn was insufficient, available Zn and Fe were moderate, available Cu was rich, and available B was very plentiful.②Significant negative correlations were observed between available contents of Mn, Zn, Fe, Cu and soil pH. The effect of organic matter content on available Fe and Cu was significant in arid area oasis, which was significantly different from humid area.③There were differences in available contents of B, Zn and Fe among different soil types, the available contents of trace elements in the alluvial soil were significantly different from the saline soil and gray desert soil.
