为深入研究南亚热带优势树种的降水分配格局，本数据依托广西友谊关森林生态系统国家定位观测研究站，于2018年1月至2021年12月，在中国林业科学研究院热带林业实验中心林区，以南亚热带优势树种马尾松（Pinus massoniana Lamb.）和红椎（Castanopsis hystrix Miq.）为研究对象，开展林外降雨、林内透流和树干茎流连续动态监测和研究，样地布设及监测均按照规范进行。本数据集通过分析处理，统计出了红椎、马尾松林外降雨、林内透流和树干茎流24小时的实测数据，并对数据集的构建进行了说明。建立和共享本数据集可为深入研究森林水分利用格局及其对全球气候变化的响应等科学问题提供基础数据，也为南亚热带森林生态系统可持续经营与管理提供科学的参考依据。

In order to conduct in-depth research on the precipitation distribution pattern of dominant tree species in the South Asian tropics, this data is based on the National Positioning Observation and Research Station of the Youyiguan Forest Ecosystem in Guangxi. From January 2018 to December 2021, in the forest area of the Tropical Forestry Experimental Center of the Chinese Academy of Forestry, the dominant tree species in the South Asian tropics, Pinus massoniana Lamb. and Castanopsis hystrix Miq., were used as research objects to carry out continuous dynamic monitoring and research on rainfall outside the forest, runoff inside the forest, and stem flow. The sample plot layout and monitoring were carried out in accordance with regulations. This dataset has been analyzed and processed to obtain 24-hour measured data on rainfall outside the Red Pine and Masson Pine forests, internal runoff, and trunk flow. The construction of the dataset has also been explained. Establishing and sharing this dataset can provide fundamental data for in-depth research on forest water use patterns and their response to global climate change, as well as scientific reference for sustainable management and management of South Asian tropical forest ecosystems.
