摘要:以湖南省马尾松飞播林176块样地资料为基础,通过立地条件、林分年龄、林分密度的分级组合,对马尾松飞播林单株和林分生物量、生物量结构特征与林分生产力进行了研究。结果表明:马尾松单株生物量最大为181.12 kg,最小为15.73 kg;马尾松林分生物量最大为84.49 t.hm-2,最小为8.85 t.hm-2;单株和林分生物量最大者分别是最小者的11.5倍和9.5倍,单株生物量的变化幅度较林分大;单株和林分各组合的生物量排序为树干>树根>树枝>树皮>树叶;不同年龄、不同立地、不同林分密度马尾松飞播林净生产力差异显著,最大者比最小者高出5.52 t.hm-2.a-1,是它的19.4倍;研究结果可为马尾松飞播林的综合经营与管理提供科学依据。
Through classifying and combining of site condition, forest age and density, the single-tree biomass, forest biomass, structural characteristics and productivity of aerially seeded Pinus massoniana plantations in Hu' nan province were studied based on 176 standard plots' data. The results are as follows. The biggest biomass values of single-tree or stands were 181.12 kg and 84.49 t·hm^-2 respectively,and the smallest ones were 15.73 kg and 8.85 t·hm^-2, and the biggest were 11.5 times and 9.5 times as much as that of the lowest, so it could be seen that the biomass of single-tree had a more wide changing extent than stands'. For every combination type, the biomass of single-tree or stands all showed the regularity of trunk 〉 root 〉 branch 〉 bark 〉 leaf. In different site indexes and stand densities, the net productivity had extraordinary difference for different ages so that the biggest was 19.4 times as much as that of the lowest, exceeding 5.52 t·hm^-2·a^-1. These results could offer some scientific basis for comprehensively supervising and managing of aerially seeded Pinus massoniana plantations.
