摘　　要：以桓仁县和平林场的胡桃楸林为研究对象,采用枝解析的方法,在不同林分条件下布设样地,选取18株胡桃楸枝条基径测量数据,建立了基于着枝深度和胸径的基径模型。以胡桃楸基径作为变量,采用逐步回归分析的方法,分析不同植株下胸径、树高、着枝深度等对基径的影响,进而得到基径模型。Taking Juglans mandshurica in Heping Forest Farm of Huanren County in Benxi City as the research object,using the method of branch analysis,the article selects 18 Juglans mandshurica branches base diameter to measure data under different forest conditions,and establishes a crown model based on branch depth and chest diameter.Using basal diameter of Juglans mandshurica as a variable,the influence of the lower chest diameter,tree height and shoot depth on the base diameter of different plants was analyzed by stepwise regression analysis.
