兴隆山自然保护区植物物候观测研究

Phenological Research on Plant in Xinglongshan Nature Reserve

通过连续4年对兴隆山保护区青杆、油松、落叶松、白桦、山杨等5种乔木,辽东栎、灰栒子、珍株梅、紫丁香、花楸、山梅花、甘肃小檗、互叶醉鱼草、茶藨子等12种灌木,以及淫羊藿、山丹花等2种草本植物不同物候期的观测,总结出了观测物种的发芽期、展叶期、开花期、枝条生长期、结果期、落叶期等物侯现象出现的日期。分析了各物候现象随温度、日照、降水等气候条件及坡位等因素的变化而变化的关系,提出了物候观测为营林生产、病虫害防治、生态旅游等活动服务的建议。

Through the observation was conducted on different phenology of 5 species including Picea wilsonii, Pinus tabulaeformis, Larix principis-rupprechtii, Betula platyphyUa and Populus dayidiaria,12 species of shrub including Quercus liaotungensis, Cotoneaster acutifolius, Sorbaria kirilowii, Syringa oblata., Sorbus koehneana, Philadelphus incanus, Berberis kansuensis, Buddleja alternifolia and Ribes alpestre,2 species of herb including Epimedium brevicornum and Lilium pumilum for four years in Xinglongshan Nature Reserve, the results showed that the occurrence date of phenological phenomenon such as of bud-ding stage, leaf-expansion stage, flowering stage, branch growth stage, fruiting stage and leaf-fall stage of species. Meanwhile, phenological phenomenon changed with the change of factors such as climate conditions including temper-ature, light, precipitation and slope position were analyzed, moreover, the suggestion of phonological observation for service production, pest disease control and ecotourism were put forward.
