摘要:
在黑里河自然保护区内设立面积为1.96hm2的固定样地，用样方法对油松林物种组成及其分布进行调查分析。为了对天然油松林的格局分布状况进行更深入、更明确的认识，运用均匀度、点格局、角尺度3种格局研究方法对样地中的主要树种的空间格局进行了分析。结果表明：乔木层中油松是优势树种。主要伴生树种有糠椴、蒙古栎、色木槭和白桦。各主要伴生树种均为集群分布。油松种群在1～65 m的尺度上呈聚集分布，当尺度大于65m时呈随机分布。油松幼树和小树为聚集分布，油松大树为随机分布。3种分析方法分析结果一致。3种方法在格局检验上各有优势。研究可为以后的种群格局研究在方法选择上提供参考。
Abstract:
A Pinus tabulaeformis forest which was established in Heilihe natural reserve with the area of 1.96hm2 in Inner Mongolia was investigated by sampling methods.The objective of the study was to obtain a better understanding of the structure of Pinus Tabulaeformis Forest.Spatial patterns of main tree species were analyzed by uniform index analysis,point pattern analysis and angle index analysis.Pinus tabulaeformis was dominant species in arbor layer.The main concomitance species were Tilia mandshurca,Quercus mongolica,Acermono and Betul platyphylla.Main concomitance species showed a concentrated distribution in the forest.Pinus tabulaeformis showed an aggregated distribution at scale of 1～65m and random distribution at scale of 65～70m.The saplings and the small trees of Pinus tabulaeformis showed an aggregate distribution,but the big trees showed a random distribution.Every method has its own superiority.This study will supply theoretic foundation for the future research.
