摘  要:
为了对沙质海岸火炬松人工林的合理经营提供基础资料和科学依据,我们于2003年对胶南沙质海岸海防林9年生火炬松幼树的生物量进行研究,结果表明:随年龄的增长,火炬松累积生物量在各器官的分配比例有所差异,树干在生物量中所占的比重逐渐增大,树枝和树叶在生物量中所占的比重则随年龄的增长基本呈下降趋势;火炬松生物量的空间分布不均匀,81.6%的生物量分布在树干3.5m以下,3.5m以上部分仅分布着大约18.4%的生物量,枝叶在树干上的分布不成比例;用W=aDb能很好地估计火炬松人工幼林生物量,且精确度高,R2值达0.9以上。

摘  要:
In 2003,the biomass of 9-year-old Pinus taeda plantation were studied in sandy coastal area in Jiaonan city in order to provide scientific basis for its suitable management.The results show:(1) the biomass distributions of various parts were diffferent with the age increasing,the ratio of trunk biomass increases gradually,while that of the branch and leaf decreases obviously.(2) The biomass spatial distribution is uneven,of which 81.6% concentrates on the trunk below 3.5m height and the others above 3.5m;the leaf distribution is not proportional to that of branch.(3) The biomass of young Pinus taedu trees can be precisely estimated by the formulas W=aDb(R2≥0.9) and Y=0.2196X2.0982.
