Soil bacteria and their biochemical characteristics on reclamation of coal mines
矿山复垦区土壤微生物及其生化特性研究

A serires of soil bacteria and their biochemical characteristics was studied on coal gangue hills by reclamation measurements.The results show that:all bacteria population and biochemical activity,genus of actinomyces and fungi,and soil nutrients on covered area with soil were better than those on coal gangue hills without soil cover.Above indexes on legume areas were better than those of grass family areas with the same soil cover.But a variety of thick soil layers from 10 to 20 cm did not show significant different in soil nutrients,physiological bacteria and their activities.Planting legume on thin soil covered\|coal gangue hills is a fast and effective measurement for reclamation of coal mining region.
