摘　　要：以连续5年全国13个花生主产省产后花生黄曲霉毒素污染监测数据为材料,分析适合我国产后花生黄曲霉毒素污染监测的抽样方法。采用方差分析、回归分析等方法,研究了我国不同花生主产省黄曲霉毒素污染程度与其标准差和变异系数之间的相关性,并以安徽省为例,研究了在一定精确度保证下的最优抽样方案。结果显示:我国各花生主产省产后花生黄曲霉毒素污染水平差异显著,污染程度与样本标准差呈正相关。以安徽省为例,在满足一定抽样精度要求下,最优抽样方案为选取8个花生主产县市,每个县市随机选取8个村,每个村抽取1个样本。According to the monitoring data of aflatoxin contamination in national post- harvest peanut of five consecutive years. A suitable sampling method of monitoring aflatoxin contamination in post- harvest peanut in our county was analyzed. The relationship among aflatoxin contamination degree,standard deviation and variable coefficient in different main peanut producing provinces in China was studied,the adopted methods were variance analysis and regression analysis. In Anhui Province,an optimal sampling scheme under an acceptable accuracy was studied. The results revealed that the difference in aflatoxin contamination level of post- harvest peanut among Chinese main peanut producing provinces was significant and the sample variance was positively related with aflatoxin contamination degree. Under an acceptable accuracy,one sample from each village was selected as the most optimal sampling plan in Anhui Province,and there were eight villages from each of eight main peanut producting counties.
