%X In this paper, a tank shooting range in a training ground in the southwest of China was investigated, and the content of Cu, Pb, Zn, Co and Ni in the soil was monitored and analyzed. Evaluation of pollution in the sampling area was applied through the single factor index method and the composite pollution index Nemrow method, and the pollution index distribution map was worked out by Arcgis software. The evaluation result shows that: Cu, Pb, Zn, Co and Ni in the tank shooting range have different degrees of pollution respectively, the average composite pollution index Nemrow reaches 1.64.The highest single-factor pollution index of Co reaches 3.84, so Co is the priority element to be monitored in the heavy metal pollution control of soil in future. The pollution index distribution map shows that: the heavy metal pollution is particularly serious in the area of dropping bombs. The pollution distributing characters of Cu and Pb are similar, Zn, Co and Ni have similar characters. The author considers that, the migration of Ni and Pb is strong under the combined effect of various conditions in the shooting range, and the migration of Cu is weak. The sources of heavy metal pollution comprise residual cannonballs, bullets, and explosives. The residual shells and bullets in the soil could lead to a permanent soil contamination of heavy metals.
