黄浦江中上游杨树人工林生态系统碳储量研究
Carbon storage of poplar plantations in upper and middle reaches of Huangpu River,Shanghai
摘要
Abstract
Poplar tree is a fast growing and strong adaptability tree species,which is one of the important tree species used for fast-growing forest silviculture in our country.In this study,poplar plantations were studied and allometric equations for different organs such as root,trunk,bark,branch and foliage of poplar tree were established in the upper and middle reaches of Huangpu River.The carbon storage of tree biomass,forest floor and soils (0-50 cm)were es-timated in three 9 year-old stands.The results showed that there was a significantly relationship between individual biomass and the diameter at breast height for the allometric equation in each organs,with the coefficient of determina-tion(R 2 =0.96-0.99,P <0.001).Total carbon storage in the poplar tree stands was 90.9 thm-2 .In the total car-bon storage of the poplar tree stands,tree biomass carbon storage proportionally accounted for 36.6%,and each or-gans ranked as:trunk>root>branch>bark>foliage.The forest floor was accounted 1.7%.The soil was the biggest part which accounted 61.6%.This result indicated that the poplar young plantations currently were at fast-growing stage,which had an important role for carbon sequestration management in Shanghai.关键词
