摘要
本文对信阳市土壤有机碳库(Soil Organic Carbon,SOC)储量与有机碳密度进行了估算,探讨了信阳市SOC分布特点。研究结果显示,信阳市0～1m土体内有机碳储量约为0.11Pg,其中土壤耕层内约为0.04Pg。0～1m土体平均SOC密度为6.02kg/m2,耕层SOC密度为2.13kg/m2,信阳表层SOC储量所占比率小于全国平均水平。
The paper estimates the density and reserves of soil organic carbon （SOC） in Xinyang City,and analyzes the characteristics of SOC＇s distribution. The result shows：the total amount of SOC in soil body of 1m depth is about 0.11 Pg,and there is about 0.04Pg in cultivating layer of the soil. The average SOC density in soil body of 1m is 6.02 kg/m2 and that in soil body of 0.2 m depth is 2.13 kg/m2. The reserves＇ rate of SOC in soil body of 0.2m depth in Xinyang City is lower than the average rate of China.
