| 摘 要： | 通过对浙江古田山自然保护区4个主要阔叶树种——甜槠、木荷、青冈和石栎的调查采样,测定了4个物种共1160张叶片的叶长、叶宽和叶面积,基于此构建4个物种叶面积与叶长和(或)叶宽的8种常用回归模型。结果表明,模型SA=a(LW)+b具有最高的决定系数(R~2=0.97-0.99)和最低的均方差(MSE=0.52-1.59);幂指数模型SA=aW~b是所有单变量模型中拟合效果最佳的模型。

| Abstract: | Investigation was conducted on 4 major broadleaved species such as Castanopsis eyrei,Schima superba,Cycloblanopsis glauca,and Lithocarpus glaber in Gutianshan Natural Reserve,Zhejiang province.Leaf length(L),width(W) and leaf area(LA) of 1 160 leaves of 4 species were determined.8 common regression models were established.The results showed that the model SA = a(LW)+b had the highest determination coefficient of(R~2 = 0.97-0.99) and the lowest mean square error(MSE = 0.52-1.59),and thus was the most accurat... |
