Comparison of Aboveground Biomass and Carbon Storage Between Near-Natural and Artificial Dendrocalamus giganteus Forest
摘要
Abstract
The aboveground biomass and the carbon storage of Dendrocalamus giganteus under near-natural cultivation and artificial cultivation are compared and analyzed in this paper.The aboveground biomass and carbon content of individual plants at different slope directions(sunny and shady slopes)and with different culm ages(1,2,3,and 4-year old)under the two modes of cultivation are measured by the dry-burning method.The results show that:1)Artificial forests are better in the age structure of bamboo clumps than near-natural forests;2)The average aboveground biomass of individual plants are significantly different in different stands(P<0.05),with the order of sunny slope in near-natural forest(62.99 kg)>sunny slope in artificial forest(59.66 kg)>shady slope in artificial forest(57.95 kg)>shady slope near-natural forest(54.51 kg).The biomass of D.giganteus is significantly higher in culms than in branches and leaves,and decreases with the increase of age;3)The carbon storage of individual plants is not significantly different among different stands(P>0.05),and different organs of individual plants have different carbon storage in the rank of leaves<branches<culms;4)The carbon storage of individual bamboo plant in each stand is ordered as sunny slope in near-natural forest(26.33 kg)>sunny slope in artificial forest(25.53 kg)>shade slope in artificial forest(25.23 kg)>shade slope in near-natural forest(23.55 kg);and 5)The carbon storage of D.giganteus forest per unit area in Cangyuan county is 207.85 t/ha in near-natural forests and 81.56 t/ha in artificial forests,and the carbon storage of D.giganteus in near-natural forests is much higher than in artificial forests.The results of the study can provide a scientific basis for the cultivation and sink development of D.giganteus in Yunnan province.关键词
