| 摘 要： | 依据20年生望天树人工林林木的生长调查及平均木的树干解析材料,分析了其林木个体的胸径、树高和材积的生长过程和规律,结果表明:在其人工林中望天树林木的前期生长迅速,20年生时林木个体的带皮胸径、树高和带皮材积分别达到19.4 cm,19.8 m和0.298 m3。其相应的年均生长量分别达到0.97 cm、0.99 m和0.0149 m3;望天树林木个体的胸径、树高和材积生长在6年生前较为缓慢,至14年生左右达到高峰,此后呈下降的趋势。依此,建立了望天树人工林林木个体的胸径、树高、材积生长模型。

| Abstract: | The process and law of DBH,height and volume growing of Parashorea chinensis individuals in 20 years old man-made forest were studied on the data of investigation and trunk analysis.The study results showed that the Parashorea chinensis individuals in man-made forest had fast growth speed in earlier stage,the DBH,height and volume reached 19.4 cm,19.8 m and 0.298 m3 respectively,with the corresponding growth increment of 0.97 cm,0.99 m and 0.0149 m3 respectively.It was found that the earlier 6 years was the stage with slow growth,the peak occurred in 14th year after planting,next showing the tendency of decline.Based on the study results,the growth model of Parashorea chinensis was established. |
