摘要
从常量元素的角度进行研究,探讨广西沿海地区研究区重金属对稻田的污染程度及其生物有效态,常量元素对土壤中重金属形态的影响。研究发现研究区与我国其他地区相比,重金属含量较低,但是有效态所占比例较高,潜在的生态危害最严重;重金属各形态所占比例不同,影响因素也是不相同的,希望对广大同行提供一定参考。
This paper has its view from the perspective of major elements. The research area is selected in Qinzhou,Fangchenggang and Beihai of Guangxi. Through the field sampling and indoor work,the pollution degree and bioavailability of heavy metals in paddy soils were studied. The effects of major elements on heavy metal speciation in paddy soils were studied. It is found that the study area compared with other areas in China. The heavy metal content is low but available in higher proportion with the most serious potential ecological risk of heavy metals. The proportion of different influence factors is not the same. We hope to provide some reference for the majority of peers.
