图2 白颜树各径级的成对相关函数。 实线表示成对相关函数, 虚线表示99%包迹线。零模型为完全空间随机模型(CSR)和sigma = 15 m的异质泊松模型(HP)。

Fig. 2 Univariate pair-correlation functions of different age classes of Gironniera subaequalis. Solid lines are pair-correlation functions, and dotted lines are 99% confidence envelopes. Null models: complete spatial randomness (CSR) and Heterogeneous Poisson (HP) with sigma = 15 m.
