油松抗旱生理机制及造林技术研究
摘 要
油松（Pinus tabuliformis）作为我国北方重要的造林树种，其抗旱性能直接影响着森林生态系统的稳定性和生产力。本研究旨在探讨油松在干旱条件下的生理响应机制及其造林技术优化策略。通过野外调查与室内实验相结合的方法，系统分析了不同水分条件下油松的生理指标变化，包括叶片水势、气孔导度、光合作用效率及抗氧化酶活性等。研究发现，油松在干旱胁迫下表现出显著的生理适应性，如通过降低气孔导度和提高抗氧化酶活性来减少水分损失和氧化损伤。此外，本研究还提出了基于土壤水分管理的造林技术优化方案，包括合理配置灌溉系统和选择适宜的造林季节，以提高油松的成活率和生长性能。研究结果表明，科学的水分管理和生理监测可以有效增强油松的抗旱能力，为我国北方干旱地区的林业可持续发展提供了理论依据和技术支持。

STUDY ON PHYSIOLOGICAL MECHANISM OF DROUGHT RESISTANCE AND AFFORESTATION TECHNOLOGY OF TABULAEFORMIS
ABSTRACT
As an important afforestation tree species in northern China, the drought resistance of tabulaeformis (Pinus tabuliformis) directly affects the stability and productivity of forest ecosystem. This study aimed to investigate the physiological response mechanism of L. tabulaeformis under drought conditions and its afforestation technology optimization strategies. By combining field investigation and indoor experiment, the physiological indexes of pine under different water conditions, including leaf water potential, stomatal conductance, photosynthesis efficiency and antioxidant enzyme activity. It was found that solpine showed significant physiological adaptations under drought stress, such as reducing water loss and oxidative damage by reducing stomatal conductance and improving antioxidant enzyme activity. Furthermore, this study presents an optimization scheme for afforestation techniques based on soil water management, including rational allocation of irrigation system and selection of suitable afforestation season to improve the pine survival rate and growth performance. The results show that scientific water management and physiological monitoring can effectively enhance the drought resistance of tabulaeformis, and provide theoretical basis and technical support for the sustainable development of forestry in arid areas of northern China.
