摘要

[目的

]

分析区域森林资源的碳储量大小及分布规律

为地方森林碳汇经营管理和规划提供科学依据. [方法

]

基于河北省森林资源清查数据

乔木树种采用方精云建立的生物量换算因子连续函数法

灌木和经济林采用平均生物量法

结合不同树种分子式含碳率

对秦皇岛市森林植储量和碳密度进行了估算

并运用ARCGIS软件对其空间分布进行了分析. [结果

2005年

秦皇岛市森林植被总碳储量为4.30×10

森林植被平均碳密度为11.72 t/hm

.全市各区县森林植被碳储量空间分布上有显著差异

表现为"北部山区和中部丘陵高

南部平原低"的空间格局

而植被碳密度呈现相反的趋势.林分碳储量占总碳储量的56.04%

林分平均碳密度为12.09 t/hm

.林分针阔分明

阔叶林碳储量略大于针叶林碳储量

天然林碳储量大于人工林碳储量.全市林分碳储量以中、幼龄林为主

二者各自占林分总碳储量的24.07%和56.31%. [结论

]

未来秦皇岛市森林植被仍具有较大的固碳能力.

Abstract

[Objective] The objective of this study is to analyze the carbon storage and spatial distribution of regional forest resources in order to provide a scientific basis for management and planning for the local forest carbon sinks. [Methods] Based on the forest resource inventory data in Hebei Province

the carbon storage and density in Qinhuangdao City were calculated. The biomass expansion factor continuous function method established by Fang Jingyun was used to calculate carbon stock in tree species. The average biomass was used to calculate carbon stock in shrubs and economic forest. [Results] In 2005

the carbon storage of forest vegetation was 4.30×106 t

the average carbon density was 11.72 t/hm2. The spatial distribution of forest vegetation carbon storage exhibited a declining trend from north to south

whereas carbon density gradually increased in the same direction. The carbon storage of forest stand accounted for 56.04% of total forest vegetation carbon storage

and average carbon density of forest stand was 12.09 t/hm2

respectively. Natural forest stands was higher than artificial forest in carbon storage

and the carbon sequestration of forest stand was mainly distributed in young and middle-aged forest

which accounted for 56.31% and 24.70% of carbon storage

respectively. [Conclusion] Forest vegetation have a great potential for carbon sequestration in Qinhuangdao City.
