Soil microbial community characteristics and indicator function in coal gangue mountains

WANG Jiping;PANG Bilin;YU Yajun;College of Geography Sciences,Shanxi Normal University;  
Soil microbial community is an important indicator of soil ecological function. Therefore,study on soil microbial community characteristics is very significant for reclamation of coal gangue mountains. The 3a( R-3a),5a( R-5a) and 7a( R-7a) of total reclaimed soil microbial concentration and microbial community concentration in reclamation land of coal gangue mountain in Cao village coal mine,Shanxi province,were examined by the method of phospholipid fatty acids( PLFA),and the indicated microbe about the change of soil quality in coal gangue mountain was analyzed. The results showed that:( 1) After the reclamation of coal gangue mountain,the total concentration of soil microbe and the concentration of soil microbial communities increased with the increase of reclamation years. It shows that the coal gangue mountain reclamation soil quality has improved.( 2)The total soil microbe concentration and microbial community concentration were lower than ordinary orchards( CK). It shows that reclaimed soil still lower than CK.( 3) i15: 1G and 16: 0 IN common bacteria,18: 1 w9c in fungi,i15: 0 and a15: 0 in gram positive bacteria,and 11Me18: 1w7c and 18: 1w5c in gram negative bacteria can be used as the indicators of characteristics of phospholipid fatty acid to improve soil quality conditions in coal gangue mountain reclamation.
