Abstract: The drag of windbreak is analysed by impulse theorem in this paper.A simulation model of drag coefficient of windbreak,Cd=(l.8+0.2a)(1-a)sin2ω,is presented, and it is tested in terms of those data from published papers.A parallel-force of windbreak is also discussed.The parallel -force of windbreak whose value is 0.7—1.1% of the normal force can be neglected.
Key words: Drag of windbreak, Drag coefficient of windbreak, Permeability of windbreak, soil heavy metal concentrations, partial least squares regression (PLSR), Yushu County., vegetation spectral reflectance, hyperspectral images
