- Abstract:
- To reveal the change of soil quality in the reclamation coal waste pile and provide theoretical guidance for coal waste pile vegetation reclamation, soil microbial functional bacteria and the influence factors on coal waste pile in different reclamation years were studied. The reclamation lands of 4 a (R4a), 6 a (R6a) and 8 a (R8a) after reclamation on coal waste pile were taken as the case in Cao Village coal mine of Shanxi Province. The changes of soil aerobic nitrogen fixing bacteria, ammonifying bacteria, cellulose decomposing bacteria, organic phosphorus and inorganic phosphorus bacteria of 3 kinds of reclamation years and the relationship between the soil function microbe and the soil physical-chemical properties were analyzed. The results showed that the total amount of bacteria presented the rising trend with reclamation years, aerobic nitrogen fixing bacteria, ammonifying bacteria, organic phosphorus bacteria and inorganic phosphorus bacteria increased with reclamation years, but the cellulose decomposing bacteria first increased and then decreased. Correlation analysis showed that ammonifying bacteria and aerobic cellulose decomposing bacteria were significantly affected by soil properties, and the principal component analysis showed that soil available phosphorus, available nitrogen, soil moisture content were the main factors influencing soil microbial functional bacteria.
