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.

Key words: Chengdu economic region, soil magnetic susceptibility, pollution, relativity
