| 摘 要： | 对吉林西部三个主要农牧区(洮南市、通榆县和乾安县)50个表层土样进行测试,探究其土壤铁形态分布及其与土壤性质的关系。研究结果表明,其土壤铁形态的含量分布为:残渣态铁(A)铁锰结合态铁(B)腐植酸结合态铁(C)碳酸盐态铁(D)强有机结合态铁(E)水溶态铁(F)离子交换态铁(G),主要以A形式存在,且全铁平均含量均低于中国铁元素背景值。A与阳离子交换量(CEC)呈极显著正相关,B与p H值呈极显著正相关,C、E与有机质呈极显著正相关。A与土壤矿质元素的关系最为密切,C、D、G次之。各形态铁之间,B、C、D两两呈极显著正相关,其他形态铁彼此间关系不大。

| Abstract: | Through investigating 50 surface soil samples of three agricultural and pastoral areas (Taonan City， Tongyu County and Qian’an County) in western Jilin，the authors explored form distribution and the relations between soil properties and soil iron form． The results show there exist 7 forms of iron，including residual phase (A) ＞ Fe- - Mn oxide phase (B) ＞ humic acid phase (C) ＞ carbonate phase (D) ＞ strong organic phase (E) ＞ water solubility phase (F) ＞ exchangeable phase (G)． A is the main form in soil of western Jilin，and the av- erage iron content of soil is lower than the background value in China． There is a significantly positive correlation between Caption Exchange Capacity (CEC) and A，soil pH and B，soil organic matter content and C，E． Soil mineral elements are significantly correlated with A． C，D and G are the next． The relations in different forms of soil iron show that B，C and D have significantly positive correlations with each other，while the other forms have little correlation． |
