图3 白颜树各个生活史阶段之间的双变量成对相关函数。实线表示双变量成对相关函数; 虚线表示99%包迹线。 A, 包迹线采用完全空间随机零模型的幼树与中龄树的关系。B, 包迹线采用先决条件零模型的幼树与中龄树的关系。C, 包迹线采用完全空间随机零模型的幼树与成年树的关系。D, 包迹线采用先决条件零模型的幼树与成年树的关系。E, 包迹线采用完全空间随机零模型的中龄树与成年树的关系。F, 包迹线采用先决条件零模型的中龄树与成年树的关系。

Fig. 3 Bivariate pair-correlation functions between pairs of life-history stages of Gironniera subaequalis. Solid lines are bivariate pair-correlation functions and dotted lines are 99% confidence envelopes. A, Relationship between young trees and middle-aged trees with envelopes calculated by complete spatial randomness null model. B, Relationship between young trees and middle-aged trees with envelops calculated by antecedent condition null model. C, Relationship between young trees and adult trees with envelopes calculated by complete spatial randomness null model. D, Relationship between young trees and adult trees with envelops calculated by antecedent condition null model. E, Relationship between middle-aged trees and adult trees with envelopes calculated by complete spatial randomness null model. F, Relationship between middle-aged trees and adult trees with envelops calculated by antecedent condition null model.
