以峡江县湿地松人工林中幼龄林为总体,以连清样地为样本,用坡向坡位(以数字化度量)、林龄、样地株数为说明变量,以样地立木进界平均胸径为基准变量,建立预估模型。建模结果表明,不论一元线性模型或二元线性模型均取得了较大的复相关系数与较高的显著水平。
Taking the young and middle-aged forests of Slash pine plantation in Xiajiang County as a whole and the sampling plots of Lianqing County as samples, the slope slope position (digitized measure), the age of forest and the number of sample plots were used as explanatory variables. DBH as the baseline variable to establish the estimated model. The modeling results show that the larger complex correlation coefficient and the higher significant level are obtained both in the linear model and the binary linear model.
