黄浦江上游主要树种水源涵养林生态系统碳储量
Carbon storage of main tree species plantations for water resources conservation in upper reaches of Huangpu River, Shanghai
摘要
Abstract
To investigate the carbon storage and its distribution in forest ecosystem is essential for assessing the ecosystem services and managing carbon-sink forest at local and regional scales. Elaeocarpus sylvestris, Cinnamomum camphora, Koelreuteria integrifolia, and Liriodendron chinense are the main tree species in the plantations for water resources conservation in upper reaches of Huangpu River, Shanghai. In this study, the biomass equations for these tree species were established, and the carbon storage of tree biomass, forest floor, and soil (0-40 cm) in these 9 year-old stands were estimated. There was a good relationship between the individual tree biomass and the diameter at breast height for these tree species, with the coefficient of determination (R2) >0. 9. The total carbon storage in the four tree stands were 117. 32, 127. 38 , 105. 87 , and 80. 93 t· hm-2, among which, tree biomass carbon accounted for 35. 1% , 44. 6% , 35. 2% , and 19. 0% , forest floor carbon accounted for 1.2%, 1.9%, 1.2%, and 0. 6% , and soil carbon accounted for 63. 7% , 53. 5% , 63. 6% , and 80. 4% , respectively, which indicated that these young plantations were at fast-growing stage, with a great potential of carbon sequestration.关键词
