A dataset of daily carbon flux observations in a Quercus variabilis plantation in Henan Xiaolangdi from 2011 to 2020
China ranks first globally in planted forest area,which plays an important role in mitigating climate change and enhancing regional carbon cycling.The South Taihang Mountain region is an integral part of the key ecological zones along the Yellow River in China.Studying carbon flux observations in plantations in this region is of great significance for understanding the impact mechanism of climate change on forest carbon sinks in the key ecological zones along the Yellow River.Quercus variabilis is one of the most widely distributed natural tree species in China,and also a primary tree species for afforestation in mountainous regions with extremely high economic and ecological value.This dataset is the daily carbon flux data product from the Quercus variabilis plantation ecosystem accumulated by Henan Xiaolangdi Forest Ecosystem National Observation and Research Station from 2011 to 2020.The dataset covers the data on net ecosystem carbon exchange(NEE),ecosystem respiration(RE),and gross ecosystem primary productivity(GPP).The data processing follows the standard quality control system of ChinaFLUX.This dataset can provide support for analyzing the response and mechanism of plantations in this region to global climate change,and it can also serve as a foundation for managing carbon sinks of plantations in the key ecological zones along the Yellow River.
