Paper Title:
Impact of Different Land Use on Topsoil Organic Carbon Density in Anhui Province
  Abstract

Abstract:Carbon storage and sequestration is considered to be an important issue in study of terrestrial C cycling and global climatic change.Regional C pool estimate is a fundamental data for describing C pool dynamics under human activities.This paper deals with a provincial baseline topsoil C pool estimate by using the soil series data collected from the 2nd national soil survey.The total topsoil SOC density is(31.64±16.39)C/hm2 ,with (36.36±18.75)C/hm2 from the forest soils,(17.58±6.07)C/hm2 from dryland soils and(27.7±6.72)C/hm2 from the plow layer of paddy soil and(14.11±6.44)C/hm2 from plow layer.The estimated total topsoil SOC pool is 0.28Pg,with 0.14Pg in the forest soils,0.05Pg in the dryland soils and 0.09Pg in paddy soils.The SOC density and pool was found reflecting the impacts by land use patterns.The SOC storage was found related to the clay content and N enrichment in soils.
