摘  要：
对黎塘岩溶区铁锰结核胁迫下土壤溶液化学特征进行了分析。结果表明,与农田灌溉用水相比较,浅层、深层K、Na均表现为减少,Ca、Mg表现为增加,Mg浓度分别是农田灌溉用水的3.98倍、2.36倍,而微量元素浓度表现为显著减少;主要元素K、Na、Ca、Mg以及微量元素Pb、Cr、Cu淋淀系数小于100%,Fe、Zn、Mn的淋淀系数大于100%;相关分析表明,pH与Fe、Mn含量达到了极显著正相关,相关系数分别为0.69、0.66,电导率与Fe、Mn含量达到了显著正相关,相关系数分别为0.47、0.50,氧化还原电位与Fe、Mn含量达到了显著负相关,相关系数均为-0.52,说明铁锰结核的形成受pH、电导率、氧化还原电位的影响。

摘  要：
The chemical characteritics of soil solution under Fe-Mn nodules in Litang karst area were analyzed. The results showed that compared with water for farmland irrigation, in shallow and deep soil,the contents of K、Na decreased while Ca、Mg increased. The content of Mg were 3.98 times and 2.36 times more than that of water for farmland irrigation. The content of trace element showed significant reduction. Filtering and precipitation of K,Na,Ca,Mg and Pb,Cr,Cu were less than100%,while Fe,Mn,Zn were more than 100%. The correlation analysis showed that pH had signifinantly positive correlation with Fe,Mn, with the correlation coefficients of 0.69 and 0.66, respectively. Conductivity had significantly positive correlation with Fe、Mn, with the correlation coefficients of 0.47 and 0.50 respectively. Redox potential had significantly negative correlation with Fe、Mn, with the correlation coefficients of both-0.52, showing that there were significant effects of pH,conductivity and redox potential on the formation of Fe-Mn nodules.
