ABSTRACT
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.
