Abstract

Abstract

The reclaimed soil of the side slope and platform of the dumpsite in Jalai Nur Open-pit Coal Mine was selected as the research object.The soil's physical and chemical properties were determined,the soil microbial communities were analyzed,the correlation between soil microbial diversities and environmental factors was analyzed and compared with the non-reclaimed soil,and the feedback response of dumping site reclamation and soil microorganisms were also explored.The experimental results indicated that differences in physical and chemical properties of the reclaimed soil were mainly related to the soil depth.Compared with the soil of 10~20 cm,the physicochemical properties of 0~10 cm soil changed more greatly.Effects of soil bulk density,mechanical composition,and pH on the reclaimed soil were significantly higher than that of soil organic carbon,soil total nitrogen,and C/N ratio.The pH of the control soil was 8.87 and 8.76,much higher than the pH of the reclaimed soil.The microbial communities of the reclaimed soil were significantly different from the non-reclaimed soil.Reclamation was beneficial in improving the soil microbial communities with the soil organic carbon and total nitrogen content increasing.
