Abstract: Based on the field investigation and the data combination from literature, vegetation carbon storage, carbon density, and their spatial distribution were examined across six forest community types (Schima superba-Castanopsis fargesii community, S. superba-C. fargesii with C. sclerophylla community, S. superba-C. fargesii with Distylium myricoides community, Illicium lanceolatum-Choerospondias axillaris community, Liquidambar formosana-Pinus massoniana community and Hedyotis auricularia-Phylostachys pubescens community) in Tiantong National Forest Park, Zhejiang Province, by using the allometric biomass models for trees and shrubs. Results showed that: Among the six communities investigated, carbon storage and carbon density were highest in the S. superba-C. fargesii with C. sclerophylla community (storage: 12113.92 Mg C; density: 165.03 Mg C·hm^-2), but lowest in the I. lanceolatum-C. axillaris community (storage: 680.95 Mg C; density: 101.26 Mg C·hm^-2). Carbon storage was significantly higher in evergreen trees than in deciduous trees across six communities. Carbon density ranged from 76.08 to 144.95 Mg C·hm^-2, and from 0.16 to 20.62 Mg C·hm^-2 for evergreen trees and deciduous trees, respectively. Carbon storage was highest in stems among tree tissues in the tree layer throughout communities. Among vegetation types, evergreen broadleaved forest had the highest carbon storage (23092.39 Mg C), accounting for 81.7% of the total carbon storage in all forest types, with a carbon density of 126.17 Mg C·hm^-2. Total carbon storage for all vegetation types in Tiantong National Forest Park was 28254.22 Mg C, and the carbon density was 96.73 Mg C·hm^-2.
