An annual output of HeiDaiGou Open-pit
Mine was 25000000 tons of raw coal. Coal mining formed a large area of the bare spoil bank
which was ecological function loss. Mine ecological recovery was urgently needed (Li Yong-Geng
2004). After decades of reclamation, vegetation
of spoil bank had partial recovery through reclamation mode of tree and shrub grass. But it was
not clear for us to understand species composition, spatial pattern and distribution of the plant
community. This paper chose plant community
of spoil bank as the research object. The original vegetation (O), no reclamation spoil bank
(N) were selected as dual control plots. The existing plant communities were studied in order to
provide reference data and technical support for
improving the quality of ecological restoration
further.
