| 摘 要： | 以河北太行山区4种典型水土保持林为研究对象,对混交林(栓皮栎-侧柏)、油松林、栓皮栎林和刺槐林的乔木层各器官生物量、含碳率以及碳储量进行比较研究。结果表明:混交林、油松林、栓皮栎林和刺槐林生物量分别为51.94,86.40,90.19,18.08t/hm^2,栓皮栎林和油松林生物量高于4种水土保持林生物量的均值(61.65t/hm^2),而混交林和刺槐林生物量分别占生物量均值的84.25%,29.33%。不同林分各器官在乔木层生物量中分配顺序均表现为树干>树根>树枝>树叶。4种典型林分各器官含碳率分别为45.16%~58.93%,58.48%~64.61%,51.16%~58.37%,52.35%~62.30%。4种典型林分碳储量为10.10~53.85t/hm^2。不同林分类型各器官碳储量与生物量呈正比关系,与生物量趋势基本相同,碳储量大小表现为油松林>栓皮栎林>混交林>刺槐林。

| Abstract: | Taking four typical soil and water conservation forests in Taihang Mountain area of Hebei province as research objects.Comparative study on biomass,carbon content and carbon storage of various organs in arbor layer of mixed forest(Quercus variabilis-Platycladus orientalis),Pinus tabulaeformis,Quercus variabilis forest and Robinia pseudoacacia forest.The results showed that the biomass of mixed forest,Pinus tabulaeformis,Quercus variabilis forest and Robinia pseudoacacia forest were 51.94 t/hm^2,86.40 t/hm^2,90.19 t/hm^2 and 18.08 t/hm^2 respectively,and the biomass of Quercus variabilis and Pinus tabulaeformis forest was higher than 4 the average biomass of soil and water conservation forests(65.65 t/hm^2),the biomass of mixed forest and Robinia pseudoacacia forest only accounted for 84.25% and 29.33% of the average biomass,respectively.The order of distribution of organs in different forest stands in tree layer biomass was as follows:trunk > root > branch > leaf.The carbon content of each of the four typical stands was 45.16%~58.93%,58.48%~64.61%,51.16%~58.37%,52.35%~62.30%.The carbon storage of four typical stands is 10.10~53.85 t/hm^2.The carbon storage of each organ of different forest types was positively proportional to the biomass,which was basically the same as the biomass trend.The carbon storage size was as follows:Pinus tabulaeformis > Quercus variabilis forest > Mixed forest > Robinia pseudoacacia. |
