About 650 samples have been measured for soil organic carbon isotopes (SOCI) at an interval of 4cm from the Yuanbao Loess Section.

Climatic change over the past 9 ka in the Jiangling area, Jianghan plain: Records of organic carbon isotopes;

Paleoclimatic evolution deduced from organic carbon isotope of western Loess Plateau sediments since Last Glacial Maximum;

This paper presents a systematic review on the photosynthetic ways and fractionation processes of organic carbon isotope of terrestrial plants as well as on the influences of temperature,illumination,atmospheric CO2 concentration and moisture on the fractionation of organic carbon isotope.

The paleoclimate during the last 8 ka is presented through the high resolution organic carbon isotope records of the Poyang Lake sediments.

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).
