| 摘 要： | 通过对54个根系土和14条土壤剖面土磁参数与化学组成的分析测试、以及根系土相对应的水稻籽实样品化学分析结果，较系统地总结了成都经济区土壤磁化率特征。结果表明：①土壤磁化率在数值上主要受成土母质控制；②在根系土壤样品中，根系土磁化率比其下层土壤磁化率有不同程度的增加；③不同类型土壤的磁化率均与土壤中Cd含量呈正相关，并对土壤污染程度有较好的指示性；④利用磁化率可以对土壤进行初步分类。

| Abstract: | Based on the analysis results of magnetic susceptibility and chemical analysis of 54 paddy soil and 14 soil sections and chemical analysis results of the paddy seeds respective to paddy soil, the typical characteristics of the soil magnetic susceptibility in Chengdu economic region have been summerized systematically. The results show that: ①magnetic susceptibility of soil is mainly controlled by parent material; ②the value of magnetic susceptibility is higher in the paddy soil; ③the magnetic susceptibility in different soil type has positive correlation with the content of Cd in soil nad have good indication of the soil pollution l;④Magnetic susceptibility can be used to classify the soil preliminarily. |
