Abstract: 712 soil samples and 46 rice samples were collected in the Zishan area of Jiangxi Province to test the contents of heavy metals(such as As, Cd, etc)in the soil and rice and finally evaluate safety of land environment in the Zishan area. The test results show that soil environment quality of the study area is generally good. The clean soil area covers an area of 11 883.06 hm²,which takes up 96.82% of the total area. The slightly polluted soil area has an area of 368.66 hm²,which takes up 3.00% of the total area. The soil polluted by heavy metals is mainly distributed in Se-rich soil areas. The contents of heavy metals such as arsenic in rice samples are low and meet the national food safety standards. Absorption and enrichment ability of rice to heavy metal elements such as As is controlled by soil amount and validity. While bio-availability of heavy metals is mainly controlled by the total heave metal amount and TFe₂O₃. Soil characteristic of desiliconization and ferrallitic enrichment indicates that the biological effectiveness of heavy metals such as As is low in the area, which can be used to grow Se-rich rice.
