With Yunlong Demonstration Area of Zhuzhou city as the research object, an evaluation and analysis have been made of the pollution situation of Pb and Cd in soil by adopting the single factor index method and potential ecological hazard index method, followed by a test of the results by using the cumulative index method. The results show that the measured mass fraction of Pb and Cd in all samples were between 25.60~102.00, 0.03~0.49 mg·kg-1, respectively, with the content of Cd in 16 samples exceeding the national secondary standard of soil environmental quality. There is a slight accumulation of heavy metal Cd in the soil, especially within its depth of 0~20 cm. The integrated potential ecological hazard index is within the scope of 3.32~51.07, indicating that the integrated potential ecological risk in this region is at a slightly high level. The cumulative index test results show that there are different degrees of heavy metals Pb and Cd pollution in each region area, with the degree of pollution inversely proportional to the depth of the sampling layer. Therefore, the relevant departments should take into consideration the reduction of the soil pollution caused by agricultural activities, and the prohibition of random staking of the living garbage likely to trigger the secondary pollution.
