To assess the effects of land use on soil organic carbon fractions,soil samples were taken from Zhongliang knoll,Chongqing.

Discussing variance of forest soil organic carbon by analysis of δ~(13)C;

Effects of elevated temperature on soil organic carbon and soil respiration under subalpine coniferous forest in western Sichuan Province,China;

Effects of land use change and soil parent material on soil organic carbon;

SOC change of natural restoration for black soil farmland;

Spatial Variability of SOC of Watershed in Western Sichuan Mountains;

To examine the impact of land management practices on soil organic carbon (SOC) pools and aggregate stability of rhizospere soils,we determined SOC in whole soil and various size aggregates from two long-term experiments (16,20 a).

Effects of land use type on soil organic C and total N in a small watershed in loess hilly-gully region;

Spatio-temporal variability of soil organic C and nutrients in the oasis of the northern slope of the Tianshan Mountains;

Changes in SOC(soil organic C),TSN(total soil nitrogen),total P,Olsen P and NO-3-N were investigated in topsoil 020 cm and 0-200 cm of 5-year,10-year,and 15-year orchard of Wangdonggou watershed in Gully Region of Loess Plateau.

This paper deals with the effects of land-use change on the vertical distribution and storage of soil organic carbon(SOC) in north subtropical areas by means of field survey.

Research advances in the effect of agricultural management on the soil organic carbon(SOC) sequestration in recent years were reviewed in this paper;the effect of sink or source of soil carbon pool and its influencing factors were discussed.
