摘　　要：我国人工林面积居世界首位,在缓解气候变化和区域碳循环中具有重要作用。南太行地区是我国黄河重点生态区的重要组成部分,在该区域开展人工林通量观测研究对于理解黄河重点生态区气候变化对森林碳汇的影响机制具有重要意义。栓皮栎(Quercus variabilis)是我国天然分布最广的树种之一,也是山区的主要造林树种,具有极高的经济价值和生态价值。本数据集为河南小浪底森林生态系统国家野外科学观测研究站(简称小浪底站)自2011年累计的栓皮栎人工林生态系统日尺度碳通量数据产品,时间范围为2011年1月至2020年12月,数据指标包含净生态系统碳交换量(NEE)、生态系统呼吸(RE)和生态系统总初级生产力(GPP),数据处理参考了中国陆地生态系统通量观测研究网络(ChinaFLUX)质量控制和处理规范。本数据集可为分析该区域人工林对全球气候变化的响应及其机制提供支撑,也可为黄河重点生态区人工林碳汇管理提供数据基础。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.
