The spatial-temporal dynamics of soil seed banks of heavy metals habitat at wasted lands in drought mine area was analyzed through the field investigation and sampling in different seasons and outdoor germination experiment. The results showed that the reserves of soil seed bank varied seasonally. It reached a maximum in October, and drop down gradually to a minimum in May. The species variation trend of soil seed bank with time was similar to that of soil seed bank reserves. The seeds in the soil were mainly distributed in 0-5 cm soil layer, which accounted for 76.5% of the total number of seeds. The seed quantity reduce gradually with the increase of soil depth, and it is only 23.5% of the total number of seeds in the 5-10 cm soil layer, and even almost none in the soil layer under 10 cm.
