Abstract: In order to study the effect of the forests in Hebei prov. on Ccycle and the indirect benefit of afforestation from CO2 fixation, the correlation betweenthe wood volume increment and the live biomass including foliage, branches, roots and non-tree biomassin forests was developed. Based on this correlation and data of wood volume increment, the area of the man-made forests, and increment of forest area, the amount of CO2 fixed by forest in Hebei Province was calculated. In addition, the transfer of C by forest logging, thinning and forest treatment and was analysed, and the loss of C from decomposition after forest logging was calculated. The total Cfixation of forests in Hebei Province amound to 13,545,185 ton of CO2. Based on calculation of the investment of afforestation for Cstorage, the annual benefits of forest from Csink equatetd to 3.405 billion RMB $.
