摘要:

研究浙江省3个年龄级杉木优势林和含杉木混交林的生物量及其分布和碳储量。结果表明:杉木优势林依靠高密度种植和人工管理,在前10 年乔木层生物量达到47 t·hm-2 以上,在中龄林(11~20 年)及成熟林(21~30 年)阶段杉木优势林乔木层生物量增加很少,且都低于同龄级的含杉木混交林;含杉木混交林乔木层的生物量随着林龄增加明显增加,中龄林比幼龄林增长了147 %,成熟林比中龄林增长了28.1%;若杉木优势林改造为含杉木的混交林,碳储量至少增加0.84 t·hm-2 a-1 ;若不改良,碳储量至多增加0.21 t·hm-2 a-1

Abstract:

The biomass distribution and carbon storage were studied of three age classes of Cunninghamia lanceolata ecological service forest in Zhejiang Province.The tree-layer biomass of C.lanceolata dominant forest was over 47 t·hm-2 before 10 years by high density planting and management.At mid-aged (11-20 a) and mature (21-30 a)stage,however,tree-layer biomass of C.lanceolata dominant forest did not significantly increase,and was lower than the mixed forest containing C.lanceolata at the same age-class.The tree-layer biomass of the mixed forest containing C.lanceolata increased markedly with age,and the mid-aged forest was 147% higher than young forest and mature forest was 28.1% higher than mid-aged forest.Carbon storage could increase by 0.84 t·hm-2 per year to 0.21 t·hm-2 per year if C.lanceolata forest was transformed into a mixed forest.
