Zhifanggou small watershed on typical erosion environment is regarded as study plot to realize the effect of soil labile organic matter and carbon management index under erosion environment.We select slope cropland as contrast and analyze several indexes such as,soil total organic C(TOC),labile organic C(LOC),non-labile organic C(NLOC) and evolvement characters of carbon management index.The study indicates that every group the content of soil carbon has been on the drastic increase after vegetation restoration.The increasing range of the content of TOC,LOC and NLOC is 109%~238%,194%~212% and 65%~149% respectively.The order of their increasing speed is NLOC>TOC>LOC.Moreover,the carbon index and carbon management index have been improved remarkably compared with slope cropland and the increasing range of them is 15%~659% and 6.5%~414% respectively.The soil management level and soil system have improved observably and developed towards better direction compared with the slope cropland.Moreover,correlation analysis shows that soil fertility factors has intimate relation to TOC,LOC,NLOC,carbon index and carbon management index.Five indexes are regarded as the index reflected the evolvement of soil quality in the period of ecology restoration.The measures of vegetation restoration have enhanced the content of soil carbon and the management level of soil carbon while different measures have different effect on recovering.The order of recovering effect is mixed forest>pure forest>wasteland.Therefore the model that mixed forest is crucial and the pure forest is subsidiary should be adopted to promote ecology restoration.
