摘要: 在应用数字图象处理法测定东北西部典型杨树林带疏透度的基础上,采用逐步回归分析和推理方法分别构筑了疏透度与林带结构因子相关的主导因子模型和因配置方式和树种而异的机理模型,并阐述了两种模型在林带结构调控中的作用。

Abstract: Based on the measurement of porosity of typical poplar shelterbelts in the west part of Northeast China with digitized photographic silhouettes. dominant. factor model(DFM) and mechanism model(MM) of shelterbelt porosity are established. The DFMis made by dominant factors relating to shelterbelt structure with successive regression analysis, and the MM is constricted by tree species and their depositions with model theory. Mean-while. the application of DFM and MM in regulating shelterbelt structure are also given in this paper.
