江西金盆山林区常绿阔叶林群落生物量研究

摘要

The survey plots of evergreen broad-leaved forest were set in Jinpenshan forests,Xinfeng County,Jiangxi province in 1996.The biomass of the major forest types including Castanopsis fargesii,C.fordii Hance,C.carlesii（Hemsl.） Hayata.,and C.fissa were surveyed in 2009.The results showed that the total biomass of C.fargesii,C.fordii Hance,C.carlesii（Hemsl.） Hayata.and C.fissa were 360.8,428.0,397.7,195.0 t/hm2;The biomass mainly concentrated in aboveground,and the proportion of tree layer biomass were more than 95%;The average biomass of existing evergreen broad-leaved forest in Jinpenshan was 345.4 t/hm2;The total existing material of evergreen broad-leaved forest in Jinpenshan was 2.532 75×106 t,and the aboveground biomass was 2.060 667×106 t;The biomass of evergreen broad-leaved forest in Jinpenshan was at a high level,but it still had a large room for rising,and the biomass growth potential was large.%在1996年设置的常绿阔叶林调查样地上,对江西省信丰县金盆山林区现存常绿阔叶林主要森林类型丝栗栲林、南岭栲林、米槠林和黧蒴栲林进行连续调查,2009年底对其生物量进行测定研究,结果表明：丝栗栲林、南岭栲林、米槠林和黧蒴栲林群落总生物量分别为360.8、428.0、397.7、195.0 t/hm2,生物量主要集中在地上部分,其中乔木层生物量所占比例均在95%以上。金盆山林区现存常绿阔叶林平均生物量水平较高,为345.4 t/hm2,现存总生物量物质达2.532 75×106t,其中地上部分为2.060 667×106 t,但仍具有较大的上升空间,生物量增长潜力较大。
