摘　　要：目的探索分析湖北省潜江市小龙虾中镉含量的空间分布及聚集性,为优化潜江市小龙虾养殖产业提供科学依据。方法对潜江市38个采样点760份样品的检测数据进行空间可视化和空间自相关性分析。结果潜江市养殖小龙虾中镉含量偏高的地区主要分布在西北部和南部,Moran's I指数为-0.04,Z得分为-0.10,P值为0.92(P>0.05)。结论湖北省潜江市小龙虾中镉含量无空间聚集性,且小龙虾中镉含量检出值远低于国家标准限量值,表明潜江市养殖小龙虾食用安全性高,产业布局尚有调整空间。Objective This research explored the spatial distribution and spatial auto-correlation of cadmium content level in crayfish in Qianjiang,Hubei,which aimed to provide basis for optimizing the local crayfish breeding industry.Methods The detection data of 760 samples at 38 sample points were analyzed by the spatial visualization and autocorrelation. Results The crayfish with relative high level of cadmium source from the northwest and south part of Qianjiang,especially guanghuasi in the northwest. The Moran’s I was-0. 04,and the Z score was-0. 10 and the P value was 0. 92（ P 〉 0. 05）. Conclusion The cadmium content in crayfish in Qianjiang didn’t present spatial clustering. And the level was lower than the maximal residual level which indicate a favorable breeding environment in Qianjiang.
