2009–2018年神农架17种优势植物物候观测数据集

A dataset of 17 dominant plants phenological observation in Shennongjia(2009–2018)

植物物候常被作为一种重要的指示气候变化的代用指标。明确植物适应自然环境变化而产生的物候期变化,有助于认识自然季节变化规律,以服务农业生产和科学研究,尤其是全球变化研究。本数据集包含神农架站综合观测场2009–2018年17个优势物种的人工物候观测记录,数据分为木本植物子集和草本植物子集。木本子集主要记录了叶芽开放期、展叶期、开花始期、开花盛期、果实或种子成熟期、叶秋季变色期和落叶期等物候信息。草本子集则记录了萌动期(返青期)、开花期、果实或种子成熟期、种子散布期和黄枯期等物候信息。本数据集可以结合温度、降水等环境观测数据,分析植物对环境变化的响应及其反馈机制,为气候变化、碳循环等方面的研究提供数据支持。

Plant phenology is often used as an important indicator for climate change.Making clear the phenological changes in response to changes in the natural environment can help us understand the changing laws of seasons,which are applied to agricultural production and scientific research,especially the research on global change.The dataset contains artificial phenological observation records of 17 dominant species at the comprehensive observation field of Shennongjia station from 2009 to 2018.It is divided into a woody plant subset and a herbaceous plant subset.The woody plant subset mainly records phenological information such as leaf bud breaking phase,leaf unfolding phase,first bloom phase,full flowering phase,fruit or seed ripening phase,leaf turning to autumn color phase and leaf falling phase.The herbaceous plant subset records phenological information such as germination or turning green phase,flowering phase,fruit or seed ripening phase,seed dispersal phase and autumn wilting phase.This dataset can be used together with environmental observation data such as temperature and precipitation to analyze the response and feedback mechanism of plants to environmental changes,providing data support for studies on climate change,carbon cycle and other fields.
