In order to explore the correlation and spatial variation law of Cadmium (Cd) content in the soil around enterprises in the Fujiang River Basin, Global Moran's I and Anselin Local Moran's I were used to analyze the correlation, and the spatial structure was analyzed by using semivariogram. The results show that: the overall level of Cd in the soil around the enterprises in Fujiang River Basin is relatively low, which does not exceed the risk screening value of the national soil environmental quality standard (GB15618-2018), and only the content in some regions exceeds the risk screening value; The spatial correlation of soil Cd in different directions and distances is different. The distribution of high value cluster points and abnormal value points of soil Cd is less, most of them belong to low value cluster points and insignificant points, and they have a certain correlation with the number of enterprise distribution and geological background; The spatial variation of Cd in soil is of moderate intensity, and the spatial differences in different directions are different, according to the order from large to small: 0° > 90° > 45° >135°, the spatial differences are consistent with the distribution of local cold hot spots and outliers.
