摘要/Abstract

摘要： 利用多年的疏透度、透风系数的野外观测和风洞试验资料,给出了立体结构林带和平面结构模型林带疏透度和透风系数的关系式分别为α=β^(0.4)及α=β^(0.95)。利用台式天平测定了7种风洞模型林带的阻力,以透风系数表示林带结构,阻力为C_α=16.3(1-α)^(0.55),以疏透度表示林带结构,阻力系数为C_β=14.0。

Abstract: The cubic and plane structural shelterbelt equations expresing relation between sparsity and ventilation coefficient were α = β^0.4 and α = β^0.95 respectively, which were given by using data obtaibed from field observation and wind tunnel experiment. The resistances of seven wind tunnel model shelterbelts were determined with platform balance. The resistance coefficient was C_α = l6.3 (1-α)^0.55 when the shelterbelt structure was expressed as ventilation, and which was C_β = 14.0 when shelterbelt structure was expressed as sparisity.

Key words: Shelterbelt, Shelterbelt benefit, Wind tunnel experiment
