摘 要 ：对河南内乡宝天曼自然保护区 3 5年生天然次生锐齿栎林生物量和净生产力进行了测定和研究。结果表明 :锐齿栎林生物量为 1 4 1 .1 7t/ hm2 ,净生产力为 7.3 9t/ (hm2 · a) ,其中乔木层生物量为 1 2 8.3 0 t/ (hm2 · a) ,占总生物量的90 .88%,净生产力为 6.3 0 t/ (hm2 · a) ,占总净生产力的 85 .2 5 %,生物量平均相对生长速率为 0 .1 2 3 8。灌木层、草本层的生物量和净生产力分别占总的 0 .79%和 0 .3 7%、5 .82 %和 4 .87%。凋落物层现存量为 1 1 .2 3 t/ (hm2 · a) ,占总生物量的7.95 %,年凋落物量 3 .3 7t/ (hm2 · a) ,占总净生产力的 4 5 .60 %。净生产量与叶面积指数、叶量成正相关 ,而与叶效率成负相关。

Abstract:This paper studied biomass and net production of a 35 year natural secondary Quercus acutidentata forest in Baotianman Nature Reserve in Neixiang county,He‘nan Province.The results showed that biomass of Q.Acutidentata forest was 141 17t/hm 2,and its net production was 7.39t/(hm 2·a),in which the treelayer biomass was 128.30t/hm 2 ,which made up 90.88% of the total biomass;its net production was 6.30t/(hm 2·a),which made up 85.25% of the total net production.The average relative growth rate...
