中国物候观测网北京站典型植物物候观测数据

“中国物候观测网”北京站典型植物物候观测数据集(TPPOD_CPON_BJ-TypicalPlantPhenologicalObservationDatasetofChinesePhenologicalObservationNetwork,Beijing)是“中国物候观测网”北京站1963-2012年杏(Prunusarmeniaca)、刺槐(Robiniapseudoacacia)、紫丁香(Syringaoblata)、野菊(Dendranthemaindicum)4个代表性植物、开始展叶期、开花始期和叶全变色期3个典型物候期观测观测记录的集成汇编数据。该数据从一个方面代表了华北地区的物候变化，对研究全球变化背景下植物响应和适应气候等有一定的参考价值。

The Typical Plant Phenological Observation Dataset of the Chinese Phenological Observation Network Beijing Station (TPPOD_CPON_BJ) is an integrated and compiled phenological observation dataset. It contains observation records from 1963 to 2012 for four representative plant species—*Prunus armeniaca* (apricot), *Robinia pseudoacacia* (black locust), *Syringa oblata* (lilac), and *Dendranthema indicum* (wild chrysanthemum)—collected at the Beijing Station of the Chinese Phenological Observation Network, covering three typical phenophases: the start of leaf unfolding, initial flowering stage, and complete leaf coloration stage. To a certain extent, this dataset reflects the phenological variations in North China, and has certain reference significance for research on plant responses to and adaptation to climate under the background of global change.
