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.
