摘要:

以QuickBird卫星图像和杉木为研究对象,在对图像进行精处理的基础上,通过在图像上测定出杉木冠幅,建立了胸径和冠幅的一元回归模型:D1.3=2.221+4.393Ck,由不同冠幅值计算出的胸径查一元材积表,据此编制出一元卫星图像立木材积表;根据图像上测算出树高和冠幅,建立了二元回归模型:V=-0.24605+0.013806Ck+0.035263 H ,据此编制出了卫星图像二元立木材积表。杉木在图像上的高是通过建立杉木树高与胸径关系模型:H =D21.3(1.746+0.215 D1.3)2 测算得来

Abstract:

This paper focused on how to compile volume table of Chinese Fir according to High-resolution QuickBird image, the method is the following:The crown width of fir was measured on the intensive processed QuickBird image, and single element regression model of crown width—height of breast was built:D1.3=2.221+4.393Ck, volume of each fir tree can be looked up in the single element volume table according to different value of D 1.3 in different crown width, so mono-factor volume table can be compiled. Binary regression equation,V=-0.24605+0.013806Ck+0.035263 H, was modeled according to height and crown breadth measured on the image. The height of thee on the image can be gained by the following model:H =D21.3(1.746+0.215 D1.3)2.Dual-factor volume table was then compiled.
