摘要

【目的】本研究对苏南丘陵山区、苏北沿海滩涂区和苏北黄泛平原区不同龄级杨树人工林林下植被进行调查分析，以揭示林龄和立地条件对杨树人工林林下植被多样性的分布特征及影响因素。【方法】结合单因素、双因素和主成分分析，探讨立地条件和林龄对杨树人工林林下植被多样性特征的影响及其与土壤理化性质的相关关系。【结果】（1）在中龄林阶段，苏北黄泛平原区林下草本层 Shannon-Wiener 指数与 Margalef 指数均显著高于苏南丘陵山区（P<0.05）。（2）在近熟林阶段，苏南丘陵山区林下灌木层 Shannon-Wiener 指数和 Margalef 指数均显著高于苏北黄泛平原区（P<0.05）和沿海滩涂区（P<0.01）。双因素方差分析表明，立地条件和林龄的交互作用对林下灌木 Shannon-Wiener 指数和 Simpson 指数产生显著影响（P<0.05）。（3）杨树人工林林下灌木层的 Shannon-Wiener 指数、Simpson 指数、Margalef 指数及均匀度指数均与土壤有机碳（SOC）和全氮（TN）含量呈显著正相关。综合分析表明，苏北沿海滩涂区和苏北黄泛平原区林下灌木层多样性相对偏低，主要受 SOC、TN 等因素的影响。【结论】本研究阐明了江苏省不同立地条件下杨树人工林林下植被多样性的分布特征及其影响因素，为制定杨树人工林区域差异化经营管理措施，提高林下植被多样性，进而提升杨树人工林生产力提供了理论基础。

Abstract

[Objective] To reveal the distribution characteristics and influencing factors of understory vegetation diversity under different stand ages and site conditions, this study investigated the understory vegetation of poplar plantations of varying stand ages in the hilly region of southern Jiangsu Province, the coastal mudflats, and the alluvial plain area of northern Jiangsu Province. [Method] By combining one-way ANOVA, two-way ANOVA, and principal component analysis, the effects of site conditions and stand age on the diversity characteristics of understory vegetation in poplar plantations and their correlations with soil physical and chemical properties were explored. [Result] (1) At the middle-aged forest stage, the Shannon-Wiener and Margalef indices of the herb layer in the alluvial plain area of northern Jiangsu Province were significantly higher than those in the hilly region of southern Jiangsu Province (P<0.05). (2) At the near-mature forest stage, the Shannon-Wiener and Margalef indices of the shrub layer in the hilly region of southern Jiangsu Province were significantly higher than those in the alluvial plain area of northern Jiangsu Province (P<0.05) and those in the coastal mudflats (P<0.01). The two-way ANOVA showed that the interaction between site conditions and stand age had a significant impact on the Shannon-Wiener and Simpson indices of the understory shrubs (P<0.05). (3) The Shannon-Wiener index, Simpson index, Margalef index and Pielou's evenness index of the shrub layer in the understory of poplar plantations were significantly positively correlated with soil organic carbon (SOC) and total nitrogen (TN) content. Comprehensive analysis showed that the diversity of the shrub layer in the coastal mudflats and the alluvial plain area of northern Jiangsu Province was relatively low, and it was mainly affected by factors such as SOC and TN. [Conclusion] This study clarified the distribution characteristics and influencing factors of understory vegetation diversity under the canopy of poplar plantations in different site conditions in Jiangsu Province, which provides a theoretical basis for formulating differentiated management measures for poplar plantations at the regional level, and for enhancing the diversity of the understory vegetation to improve the productivity of poplar plantations.
