摘要: 对河南内乡宝天曼自然保护区45年生天然次生栓皮栎林的生物量和净生产力的研究表明,栓皮栎林生物量为167.6417t·hm-2, 其中乔木层为158.8382t·hm-2, 占总量的94.75%;该林净生产力为8.4880t·hm-2·a-1, 其中乔木层为7.9254t·hm-2·a-1, 生物量平均相对生长速率为0.041.灌木层的生物量和净生产力分别为0.0694和0.0456t·hm-2·a-1;而草本层的分别为0.1041和0.0908t·hm-2·a-1.凋落物现存量为8.63t·hm-2, 凋落物量为5.0395t·hm-2·a-1, 分别占总量的5.15%及59.37%.净生产量与叶面积指数、叶量成正比关系,而与叶效率呈负相关关系。

Abstract: Determinations of a 45 years old natural secondary Quercus variabilis forest in Baotianman Natural Reserve in Neixiang County, He'nan Province show that its biomass was 167.6417t·hm-2, 94.75% of which was the tree layer, and its net productivity was 8.4880t·hm-2 ·yr-1, in which, the tree layer was 7.9254t·hm-2 ·yr-1 .The average relative growth rate of biomass was 0.041.The biomass and net productivity of shrub layer were 0.0694t·hm-2 and 0.0456t·hm-2 ·yr-1, respectively, while those of herb layer were 0.1041t·hm-2 and 0.0908t·hm-2 ·yr-1, respectively.The standing storage of litter was 8.63t·hm-2, and the yearly litter was 5.0395t·hm-2 ·yr-1, which were respectively 5.15% of total biomass and 59.37% of total net productivity.The net production had a positive correlation with leaf area index(LAI)and leaf biomass, but a negative correlation with leaf efficiency.
