中国森林面积居世界第五位，覆盖了从寒温带到热带的广泛气候梯度，在全球碳循环中发挥着重要作用。过去二十年来，中国对森林土壤呼吸作用（Rs）的研究迅速增加，基于此，本数据集从截至2018年12月31日发表的文献中整理出中国未受干扰森林生态系统Rs的综合数据集，包括月Rs和同时测量的土壤温度（N=8317）、月平均Rs（N=5003）和年Rs（N=634）。此外，还记录了详细的地块信息，如地理位置、气候因素、林分特征和测量描述，以及研究了数据集的其他方面--与土壤温度拟合的Rs方程、温度敏感性（Q10）、月变化以及寒温带、温带、亚热带和热带地区的年流出量。希望该数据集能为科学界所用，以更好地理解中国森林生态系统的碳循环，减少大尺度碳预算评估的不确定性。", "ds_source": "

China ranks fifth in the world in terms of forest area, covering a wide climate gradient from cold temperate to tropical regions, and playing an important role in the global carbon cycle. In the past two decades, research on forest soil respiration (Rs) in China has rapidly increased, but the resulting Rs data needs to be summarized. Based on this, this dataset compiles a comprehensive dataset of undisturbed forest ecosystem Rs in China from literature published up to December 31, 2018, including monthly Rs and simultaneously measured soil temperature (N=8317), monthly average Rs (N=5003), and annual Rs (N=634). In addition, detailed plot information was recorded, such as geographic location, climatic factors, forest characteristics, and measurement descriptions. Studied some aspects of the dataset - the Rs equation fitted to soil temperature, temperature sensitivity (Q10), monthly variations, and annual outflows in cold temperate, temperate, subtropical, and tropical regions. I hope this dataset can be used by the scientific community to better understand the carbon cycle of China's forest ecosystems and reduce the uncertainty of large-scale carbon budget assessments.
