森林地被物类型负荷量数量分布规律的研究

THE DATA ANALYSIS OF THE SOAD OF DIFFERENT COVER PLANT TYPE IN FOREST

本文利用回归及主分量分析等方法,建立了地被物负荷量变化的数学模型。研究结果表明,郁闭度与活地被物负荷量呈负线性相关关系,龄级与其呈正线性相关关系;故郁闭度与死地被物和总地被物负荷量呈正线性相关关系,龄级与其呈正线性相关关系;蓄积量与地被物的负荷量呈线性正相关关系,但相关性较小。

This Paper builds the mathematical models of covering plant space in forest with the method of regression and principal component analysis. The result shows that the relationship of conopy density with living cover plant space expresses a negative correlation, age class expresses a positive correlation, age class expresses a positive correlation; the relationship of conopy density with the dead covering plant and general covering plant expresses a positive linear covrelation, age class expreses an indicial correlation; the relationship of volume quantity with covering space expresses positive correlation, but it is less.
