天童国家森林公园植被碳储量估算

以典型木荷-栲树群落、含苦槠的木荷-栲树群落、含杨梅叶蚊母树的木荷-栲树群落、披针叶茴香-南酸枣群落、枫香-马尾松群落、黄毛耳草-毛竹群落6种群落类型样地实测数据为基础，结合文献资料汇总，采用生物量相对生长方程法，研究了天童国家森林公园森林生态系统的植被碳储量、碳密度及其组分和空间分布特征.结果表明：野外调查的6种群落类型中，含苦槠的木荷-栲树群落碳储量（12113.92 Mg C）和碳密度（165.03 Mg C·hm^-2）均最高，披针叶茴香 南酸枣群落碳储量最低（680.95 Mg C），其碳密度为101.26 Mg C·hm^-2.各群落类型中，常绿树种的碳储量均显著高于落叶树种，其碳密度范围分别为76.08～144.95和0.16～20.62 Mg C·hm^-2.各群落类型的乔木层各组分中，植株干的碳储量均最高.各林分类型中，常绿阔叶林碳储量最高，为23092.39 Mg C，占天童林区森林生态系统碳储量的81.7%，碳密度为126.17 Mg C·hm^-2.天童国家森林公园植被总碳储量为28254.22 Mg C，碳密度为96.73 Mg C·hm^-2.

Estimation for vegetation carbon storage in Tiantong National Forest Park.

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.
