Abstract: Soil is the core of terrestrial ecosystem. Investigations into soil carbon (C) pool would clarify the role of soil in terrestrial ecosystem C cycle and global change. In the present study, 145 soil profile data collected from 2009 to 2012 were analyzed by soil type and GIS method to estimate the soil C pool in Zhejiang Province. The total amount of soil organic carbon (SOC) in Zhejiang Province was about 081~083 Pg, and the average soil carbon density was 808~837 kg·m-2. The SOC density varied within soil types. The lowest SOC density was shown as a southeast strip from Jinqu Basin to Taizhou\|Wenzhou costal area, and the SOC density increased gradually outward to the north, west and south. Finally, the advantages and disadvantages of soiltype and GIS\|estimation method in SOC evaluation were compared.
