| 摘 要： | 在分析西昌市土壤微量元素Fe、Mn、Cu、Zn有效含量状况及其分布特征的基础上,从成土母质、土地利用方式、有机质和pH等4个方面探讨其对土壤微量元素有效含量的影响。结果表明:西昌市土壤有效Fe含量丰富,有效Cu和Zn略低且分布不均,有效锰有32.18%的土壤缺乏。成土母质是重要的影响因素,第四纪紫色洪冲积物发育的土壤Fe、Mn、Zn有效含量较高,二迭纪岩浆岩洪冲积物发育的土壤有效Cu含量较高,坡残积物发育的土壤4种微量元素有效态含量均较低;水田土壤各元素有效含量均大于旱地;有机质与有效Fe、Cu间显著正相关;pH值在中性偏碱时,有效Cu和Zn含量较低。

| Abstract: | Based on the analysis of the bioavailability concentrations of Fe,Mn,Cu,Zn and the distribution characteristic in the soils of Xichang City,the effects of the soil parent material,the type of land use,the content of organic matter and pH on the bioavailability of the microelements were studied.The results showed that there were high bioavailability of Fe in Xichang soils,and the concentrations of bioavailability Cu and Zn,which being unevenly distributed,were relatively lower than that of Fe.32.18% of soil ... |
