Shelterbelt porosity model and its application

Abstract

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.

Key words: Shelterbelt, Porosity, Model, Structure regulation, stoichiometry., fire history, slope, Great Xing’an Mountains, nutrient cycle
