Using germination test

features of soil seed bank at the dump of Antaibao opencast mine were studied. As the result

Viable seeds

mainly of anniversary species were detected

which is the material base for re-vegetation. As the reclamation is prolonged

soil condition is improved

species increased

and the growth of seedling become better. Compared with the new land

species is increased greatly after the land is reclaimed by Hippophae rhamnoides

robinia pesudoacacia and grassland for 10 years. Also

the most abundant species is different due to the different vegetation. New land is good for seeds invasion

however

it is bad for seed germination and seedling growth.
