摘　　要：通过对所采集土壤样品的检测,并用直线回归方法对土壤有机质与砷汞铅含量相关性进行统计分析。结果表明:土壤有机质与砷含量呈现负的5%显著性直线相关关系,与汞含量没有显著性直线相关关系,与铅含量呈现负的1%极显著性直线相关关系。说明,随土壤有机质含量的提高,能减轻土壤中一些种类的重金属污染。Pass to collect the examination of the soil-sample, counteract the straight line returns to return a method to carry on statisticsing analysis to the soil organic quality and the arsenic mercury lead content relativity,the result express： The soil organic quality content and the arsenic content present negative 5% to show a related relation of the straight line, didnt show a related relation of the straight line with the mercury content, present with the lead content to take of 1% shows a related relation of the straight line very much. Explain, with soil the exalta- tion of the organic quality content, can ease the heavy metals nollution of some categories in the soil.
