Technology system and method of biodiversity restoration for the reclamation of opencast coal mine:a case study from the dumps in Pingshuo mine

Biodiversity provides us with the living resources and environment.However，opencast mining damages the ecological systems and biodiversity，and technology related to biodiversity was scarce in land reclamation.In order to accelerate biodiversity restoration and improve the stability of mine land reclamation ecological system，we attempted to propose biodiversity restoration technology from mining habitat reconstruction and landscape pattern optimization based on empirical technology and biodiversity restoration methods and Pingshuo opencast coal mine was taken as the example.The results showed that：habitat reconstruction and landscape structure optimization were important means to recovery biodiversity；the optimization of platform and slope of dumps promoted biodiversity；the applying of implements of soil and vegetation reconstruction and optimization of mine landscape structure could also improved biodiversity.In addition，the establishment of ecological source and ecological corridor were necessary.Due to the proportion of reclaimed cropland is large，the implementation of ecological agriculture mode and agricultural ecological landscape structure optimization should also be adopted.
