摘要: 研究了杉木人工林林分蓄积量与生物量之间的关系,并在会同杉木人工林全林整体模型基础上,提出了会同杉木人工林生物量全林预估模型为W=a1EXP{a2La3[1—EXP(—a4sa5O>)a6FH} 该模型精度除根之外,均在96%以上;成对数据比较假设检验结果各器官都有|t|0.05。(55),可以认为预估值与实际值没有显著差异,能满足森林经营要求。

Abstract: According to the study on the relation between stand volume and biomass of Chi-nese fir plantation,this paper developed the integrated stand forecast models for stand biomass based on the integrated stand growth mode (ISGM) of Chinese fir plantation in Huitong.The models are Wi=a1EXP{a2La3[1一EXP(-a4Sa5o>)a6FH} i=1,2,3,4,5 The precision of the models is greater than 96% except for root.Through the t test,there is |t|0.05(55) for all organs.Thinking of no distinct difference between the esti-mative value and obser red data,the models can meet the needs of forest management.

Key words: Chinese fir, Biomass, Stand forecast models
