A dataset of soil respiration in a subtropical evergreen broad-leaved forest at Ailao Mountain from 2010 to 2014

Subtropical forests are the largest forest type in China, and play an important role in regulating global climate change and maintaining atmospheric carbon balance. The carbon emitted by soil through respiration is the main source of atmospheric CO2, so slight changes in soil carbon pool will also significantly affect the concentration of atmospheric CO2. Therefore, at present, the size and dynamic change characteristics of soil carbon storage in subtropical forests are widely concern.In this study, soil respiration was estimated of subtropical evergreen broad-leaved forest ecosystem at Ailao Mountain by using a multichannel automated chamber system for soil respiration measurement method. Ailao Mountain Station for Subtropical Forest Ecosystem Studies is a national field station and a basic observation station of the Chinese Ecosystem Research Network. We collected soil respiration data of subtropical evergreen broad-leaved forest in Ailao Mountain from 2010 to 2014 based on a multichannel automated chamber system for soil respiration measurement platform. Including soil temperature 5cm (TS), soil moisture content 10cm (SWC) and soil respiration data (RS), divided into three types of daily, monthly and annual scale files. This dataset is of great significance for revealing the effects of climate change on soil ecological processes in subtropical evergreen broad-leaved forests, correctly assessing soil organic carbon emissions and forest ecosystem management, and provides empirical and theoretical basis for further research on the effects of global changes such as climate warming on soil respiration components, especially soil organic carbon emissions.

亚热带森林是中国面积最大的森林类型，在调节全球气候变化与维持大气碳平衡方面发挥着重要作用。土壤通过呼吸作用释放的碳是大气CO₂的主要来源，因此土壤碳库的微小变化也会显著影响大气CO₂浓度。因此，当前亚热带森林土壤碳储量的规模及其动态变化特征受到广泛关注。

本研究采用多通道自动箱式土壤呼吸测量系统，对哀牢山亚热带常绿阔叶林生态系统的土壤呼吸进行了估算。哀牢山亚热带森林生态系统研究站是国家野外台站，同时也是中国生态系统研究网络的基本观测站。基于多通道自动箱式土壤呼吸测量平台，我们收集了2010—2014年哀牢山亚热带常绿阔叶林的土壤呼吸数据。数据包括5cm土壤温度（TS）、10cm土壤含水量（SWC）及土壤呼吸数据（RS），并按日、月、年三种时间尺度分类归档。

该数据集对于揭示气候变化对亚热带常绿阔叶林土壤生态过程的影响、准确评估土壤有机碳排放及优化森林生态系统管理具有重要意义，同时为深入研究气候变暖等全球变化对土壤呼吸组分（尤其是土壤有机碳排放）的影响提供了实证与理论依据。
