摘要:
选择黑龙江省帽儿山林场天然次生林内176株10个阔叶树种的解析木,共收集了3 401个枝条的详细数据,建立了一种树冠轮廓模型。分析发现,树冠的形状随着枝深度变化,在树冠上部、中部逐渐扩展,在下部收缩,每个树种呈现不同的曲线形式,天然次生林主要阔叶树种树冠模型可分为上中层和下层两部分建模,上中层模型为hRPCA=a0+(a1)/(ln(RB))+(a2)/(ln(RB)2)+(a3)/(ln(RB)3),下层轮廓模型因种不同而有不同,即hRPCB,白桦=b00+(b1·(exp(b2)·ln(RB)-1))/(b3); hRPCB,黄菠萝=b0+b101·ln(RB)+b2·ln(RB)2; hRPCB,其他=b0+b101·ln(RB)+b22·ln(RB)2+b33·ln(RB)3。经过验证,所建立的树冠轮廓模型拟合和检验效果较好,相关系数都在0.97以上。
Abstract:
A simple crown profile model for 10 broad-leaf species in secondary forest collected from Mao’er Mountains in Heilongjiang province was developed using the data of 3 401 living branches from 176 stems. The shape of crown varied along with the depth into crown(CDIN)which expanded at the upper, middle parts of the crown, however, shrank at the lower area, the main model could be categorized into the profile model of upper, middle crown(hRPCA=a0+a1/ln RB+a2/ln(RB)2+a3/ln(RB)3)and the profile model of lower crown hRPCB,birch=b00+[b1·(exp(b2)·ln(RB)-1)]/b3; hRPCB,phellodendri=b0+b101·ln(RB)+b2·ln(RB)2; hRPCB,other=b0+b101·ln(RB)+b22·ln(RB)2+b33·ln(RB)3. The fitting and validation of these crown profile models performed very well and the correlation coefficients were all greater than 0.97.
