摘要：【目的】量化环境要素对山西省中条山油松Pinus tabuliformis人工林下物种分布影响,为进一步揭示中条山油松人工林下物种多样性维持机制提供理论依据。【方法】基于中条山油松人工林样地植物和土壤调查数据,分析环境因子对油松人工林下物种分布的影响。【结果】环境因子对灌木、草本、藤本物种分布的解释率(校正解释率)分别为45.7%(34.5%)、37.0%(20.4%)、43.4%(30.6%);油松林下物种分布主要受非生物环境影响,海拔和土壤通气性是影响该地区物种分布的关键环境因子;灌木和藤本分布主要受海拔影响,草本分布主要受土壤通气性影响,且随着海拔、土壤通气性的升高油松人工林下物种多样性下降。【结论】地形(海拔)和土壤(土壤通气性)因子对区域群落生境的关键塑造作用所形成的环境筛是影响中条山油松人工林下物种分布的关键性因子。
[Objective] This study is aimed to quantify the impact of environmental factors on the distribution of species under the Pinus tabuliformis plantation in Zhongtiao Mountain, Shanxi Province so as to provide a theoretical basis for further revealing the maintenance mechanism of species diversity under the P. tabuliformis plantation in Zhongtiao Mountain. [Method] With survey data collected of the plant and soil of different types of P. tabuliformis plantation in Zhongtiao Mountain, an analysis was conducted of the influence of environmental factors on the distribution of species under the planted P. tabuliformis plantation. [Result] The interpretation rates(adjusted explanation rates) of environmental factors on the distribution of shrubs, herbs, and liana species were 45.7%(34.5%), 37.0%(20.4%), and 43.4%(30.6%), respectively. The distribution of species under the P. tabuliformis plantation is mainly affected by abiotic environment. Altitude and soil aeration are the key environmental factors that affect the distribution of species in this area. The distribution of shrubs and lianas under the P. tabuliformis plantation are mainly affected by altitude whereas the distribution of herbs was mainly affected by soil aeration, and the species diversity of the P. tabuliformis plantation declined with the increase of altitude and soil aeration. [Conclusion] The environmental filtering formed by the key shaping effects of topography(altitude) and soil(soil aeration) factors on the regional community habitat are the key factors that affect the distribution of understory species of P. tabuliformis plantation in Zhongtiao Mountain.
