摘要: 采用树干解析法分析了闽北高海拔地区湿地松人工林的生物量和生长量。结果表明:湿地松各器官的生物量大小排序为干>枝>根>叶>果,水分分配为根>干>叶>枝,单株平均含水率为56.19%;33a生湿地松种群总生物量为396 735kg/hm2,净生产力为12 022.27 kg/(hm2·a);33a生湿地松人工林的树高、胸径、单株材积分别达到了21m,24.6cm,0.380 5m3;胸径和树高分别出现3次和4次生长高峰,且高生长期与低生长期年份基本一致。树高连年生长曲线与平均生长曲线出现多次相交,材积的变化幅度相对较小。运用SPSS 13.0拟合了胸径、树高、材积总生长量与树龄之间的回归方程,拟合模型精度较高。

Abstract: The biomass and increment of Pinus elliottii plantation in high altitude area of northern Fujian were studied using method of stem analysis.The results showed that the biomass order of Pinus elliottii organs was stem>branch>root>leaf>fruit,and the distribution of moisture was root>stem>leaf>branch,the average moisture content of single plant was 56.19%.The total biomass of 33-year-old Pinus elliottii plantation was 396 735kg·hm-2,and its net productivity was 12 022.27 kg·hm-2·a-1.The height,DBH and the volume of single plant have reached 21m、24.6cm and 0.3805m3.There was 3 pinnacle in DBH growth and 4 pinnacle in height growth,the high growth rate and low growth rate of DBH are consistent with the year of height growth.The annual growth curve of height intersected with the average growth curve multiple times and changed drastically,the volume changed relatively and it did not reach the age of quantitative maturity.The total increment models of height,DBH and volume of Pinus elliottii was established through SPSS 13.0 with high accuracy.

Key words: Pinus elliottii, stem analysis, biomass, increment
