摘要
为探讨灌木生物量估测模型 ,以便得出估测灌木生物量及产量的简易方法。研究了长江三峡地区主要灌木植物的生物量及产量与植株冠幅的相关规律。结果表明 ,灌木当年生枝叶产量及地上生物量与植株冠幅呈显著 (P<0 .0 1)的正相关 :Y=a·D。
Biomass estimation model of shrubs and correlation between the crown width and the biomass of main shrubs in the Three Gorges Region of Yangtze River were studied. It was observed that there was positive correlation between the fresh weight of either new branches and leaves or above ground and crown width.
