Abstract: The study on the soil C02 release from three land types of Chinese fir plantation in Huitong,Hunan showed that:①The soil C02 release from the afforested land or the def-forested land is evidently higer than that of the closed woodland,the soil C02 release from the afforested land is somewhat higher than that of the deforested land;②The soil C02 release is positive linear correlation with the soil temperature and soil moisture at a certain range,and also with the soil C/N ratio;③The soil C02 release change with a regular circadian rhythm;④The soil C02 release from the defforested lands with differ-ent treatments is evident difference in a certain time lapse.

Key words: Chinese fir, Soil C02 release rate, Greenhouse gas
