Spring Phenological Grid Dataset of Typical Deciduous Broad-leaved Woody Plants in China from 1963 to 2015
Listed in ScienceDB
Plant phenology is an important basis for assessing the effects of global climate change, studying the structure and function of ecosystems, and developing the models of climate and land surface.
Description
Based on the Chinese Phenological Observation Network (CPON), the leaf unfolding date (LUD) and the first flowering date (FFD) of 22 woody plants from 1963 to 2015 were abstracted, including that of Fraxinus chinensis, Salix babylonica, Robinia pseudoacacia, Albizia julibrissin, Morus alba, Ulmus pumila, Armeniaca vulgaris, Cercis chinensis, etc.
Using three phenological models as Unified, UniChill and Temporal-Spatial Coupling (TSC), estimating the corresponding parameter value and testing models, the 0.5°x 0.5° grid data of the 8 species LUD and FFD among their distribution in the past 50 years was developed. The data verification results showed that the average simulation error of LUD is about 5-9 days, and the average simulation error of FFD is about 5-12 days.
