摘要:
以上海地区黄浦江中上游杨树人工林为研究对象,构建了杨树立木及各器官(根、干、皮、枝、叶)生物量方程,并对杨树人工林林分生物量(乔木层、地表枯落物层)、碳储量和土壤碳储量进行了估测。结果表明:杨树立木及各器官的生物量方程拟合效果较好(R2=0.96~0.99,P<0.001)。9年生杨树人工林生态系统碳储量为90.9 t·hm-2。其中乔木层碳储量所占比例为36.6%,乔木层各组分碳储量大小排序为树干>树根>树枝>树皮>树叶; 地表枯落物层碳储量所占比例仅为1.7%。土壤碳储量(0~50 cm)所占比例最大,为61.6%。这些杨树人工幼龄林正处于快速生长阶段,对上海地区人工林碳汇经营具有重要意义。
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 estimated 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 determination(R2=0.96-0.99,P<0.001). Total carbon storage in the poplar tree stands was 90.9 t·hm-2. In the total carbon storage of the poplar tree stands,tree biomass carbon storage proportionally accounted for 36.6%,and each organs 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.
