【目的】

内蒙古阴山山脉作为“三北”防护林体系的典型代表，如何提升其生态系统的固碳功能已成为关键问题。本研究通过测定阴山山脉中段乔木与灌木的光合相关参数，旨在探讨其光合作用及水分利用效率的日变化特征，分析环境因子对光合调控的影响，结合随机森林回归模型与聚类分析，全面评估树种的生态适应性与固碳功能，旨在为防护林体系的生态功能提升提供科学依据。

【方法】

选取阴山中段7种乔木和5种灌木，采用CI-340便携式光合仪测定其光合参数，结合斯皮尔曼相关性分析、主成分分析、随机森林回归模型与层次聚类分析，系统研究树种光合作用机制及其生态适应性差异。

【结果】

内蒙古阴山中段12种典型木本植物的光合-水分生理策略存在显著功能群分化。研究发现，乔木与灌木的净光合速率日变化呈单峰与双峰两种模式，其中蒙古扁桃等物种兼具高水分利用效率与强固碳能力，凸显其独特的“双优”适应机制。随机森林回归分析结果进一步揭示温度是驱动光合日变化的关键非线性因子，凸显了半干旱地区植物对高温胁迫的响应特征。层次聚类分析结果表明，白桦、辽东栎和蒙古扁桃属高固碳功能群，而针叶树种则采取保守型水分利用策略。本研究从生理机制与功能群视角为阴山山脉生态修复及高效固碳树种选择提供了理论基础与科学依据。

【结论】

本研究系统评估了内蒙古阴山中段主要树种的生理生态功能，并得出以下结论：首先，明确了乔木与灌木在光合及水分利用策略上存在显著差异，并揭示了温度、气孔导度与蒸腾速率在光合调控中的关键作用；其次，通过对比证实，随机森林回归模型在捕捉环境因子与光合速率的复杂非线性关系上优于传统线性方法；最后，层次聚类分析阐明了各树种在固碳能力与生态适应性上的分化类型，为差异化恢复策略提供了直接依据。

【Objective】

The middle section of the Yinshan mountains in Inner Mongolia, as a representative area of the Three-North Shelter Forest Program, faces critical challenges in enhancing ecosystem carbon sequestration functions. This study aims to investigate the diurnal variation characteristics of photosynthesis and water use efficiency (WUE) in arbor and shrub species in the Middle Section of the Yinshan Mountains, analyze the influence of environmental factors on photosynthetic regulation, and comprehensively evaluate the ecological adaptability and carbon sequestration functions of different tree species. For the first time, a combination of random forest regression models and cluster analysis is applied to provide scientific insights for improving shelter forest ecosystem functions.

【Method】

Seven arbor species and five shrub species were selected in the middle section of the Yinshan mountains, Inner Mongolia. Photosynthetic parameters were measured using a CI-340 portable photosynthesis system. Spearman's correlation analysis, principal component analysis (PCA), random forest regression modeling, and hierarchical cluster analysis were employed to explore the photosynthetic mechanisms and ecological adaptability of the species.

【Result】

The study revealed distinct diurnal variation patterns in photosynthetic activity among arbor and shrub species. Net photosynthetic rate (P_n) and WUE exhibited significant interspecific differences, with single-peak and double-peak patterns observed. Temperature, stomatal conductance, and transpiration rate were identified as key regulators of photosynthesis, particularly in coniferous species, which demonstrated higher WUE. Random forest regression analysis highlighted the critical roles of temperature and water management in photosynthetic processes. Cluster analysis further revealed marked differences in carbon sequestration capacity and ecological adaptability among species, offering critical guidance for species selection and carbon sequestration assessments.

【Conclusion】

This study underscores the significant differences in photosynthesis and WUE between arbor and shrub species in the middle section of the Yinshan mountains. Temperature, stomatal conductance, and transpiration rate were pivotal in photosynthetic regulation. Unlike traditional linear regression methods, the random forest model effectively captured the nonlinear relationships between environmental variables and photosynthetic rates. The hierarchical cluster analysis, applied for the first time in this context, identified distinct functional groups of species based on their carbon sequestration potential and ecological adaptability. These findings fill a critical gap in understanding photosynthetic mechanisms and carbon sequestration capacity within the Three-North Shelter forest program, providing a novel framework for quantitative carbon sequestration assessment and informing future afforestation and restoration strategies.
