摘要
提出利用建立相对树高曲线模型的样地数据资料和森林资源连续清查的样地数据资料计算林分形高,编制林分形高表估测林分蓄积量的方法,通过林分形高模型自检和实践检验,表明编制现实林分形高表是非常必要的,且编表方法是可行的,认为在森林资源二类调查及连续清查中有推广使用价值。
In this paper ,one method to establish the stand form-height table for estimating the stand volume is presented, based on computing the stand form-height using the sampling data for establishing the relative tree height curve models and data of the CFI.The essentiality to establish the stand form-height table and the manipulable method are expatiated by self and practical test for the stand form-height models.The high worthiness of extending-using in forestry resource subeompartment surveying and CFI is showed.
