Title: Soil Nutrients and Organic Carbon Contents with Different Reclamation Years in the Colliery Areas of Fushun City
Abstract: Through sampling soils of different years and depth in the reclaimed areas of Fushun coal mine,we analyzed the space-time change of soil nutrients and organic carbon.The statistic analysis revealed that as reclamation years increasing,the soil pH value reduced gradually compared with the no reclaimed soil and the range was between 9.95-6.58,whose maximum value appeared in no reclaims,while the minimum value appeared in the mine soil after 60 year-reclamation.Total nitrogen,available phosphorus and alkaline hydrolysis nitrogen increased year by year.In the mine soil,the potassium content was enough for plant growth.The total organic carbon content was rich because some minerals composed of carbon.With depth increasing,the pH value elevated gradually,total nitrogen,available phosphorus and alkaline hydrolysis nitrogen were declined gradually.As the duration of human influence on the soils increasing,concentrations of black carbon,and particulate organic carbon tended to decrease,while active carbon tended to increase.
