内乡宝天曼自然保护区锐齿栎林生物量和净生产力研究

对河南内乡宝天曼自然保护区35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141．17t/hm^2，净生产力为7．39t/(hm^2.a),，其中乔木层生物量为128．30t/(hm^2.a)，占总生物量的90．88％，净生产力为6．30t/(hm^2.a),占总净生产力的85．25％，生物量平均相对生长速度为0．1238。灌木层、草本层的生物量和净生产力分别占总的0．79％和0．37％、5．82％5和4．87％。调落物层现存量为11．23t/(hm^2.a)，占总生物量的7．95％，年凋落物量3．37t/(hm^2.a)，占总净生产力的45．60％，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。

Studies on biomass and net production of Quercus acutidentata forest in Baotianman Nature Reserve

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...
