摘    要:以长白落叶松(Larix algernsis Henry)人工林为研究对象,利用松江河林业局设置的8块团状枝解析标准地作为基础数据,采用树干一致性削度方程垢研究方法,建立了能预估任意部位的树冠体积(Cv(h),树冠横断面面积Ca(h)及树冠表面各Cs(h)的一致性树冠体积/冠形方程系统。由217株伐倒木树冠资料采用非线性一回归方法建立了预估全树冠方程,某一指定高度以上的树冠体积,某一指定高度处的累

关 键 词:长白落叶松  树冠  体积  横断面面积  表面积

Abstract:On the basis of study on eight branch-analytical sample plots for Larix olgensis Henry of Songjianghe Forest Bureru, using the research methods of stem that was compatible with the prediction of taper equation, a compatible crown volume and taper equation system to estimate total crown volume, crown volume above a specified height, cumulative crown sectional area and cumulative crown surface area at a specified height are presented The eqations to estimate total crown volume, crown volume above a specified height, cumulative crown sectional area and cumulative crown surface area at a specified height are developed by regression, using the data collected on crowns of 217 felled trees According to a compatible rules, crown taper indices were predicted using individuel model The crown volumes and assoiciated measures can be used to compute indices or to compute other measures such as wildlife habitat suitability or insect damage potential
Keywords:Larix Olgensis Henry  Crown volume  Crown sectional area  Crown surface area  Crown taper indices
