In order to conduct in-depth research on forest water use patterns, TDP thermal diffusion probe technology was used. Based on forest investigation, 30 artificial forests of Red Spine and Pinus massoniana were set up × Conduct continuous dynamic monitoring and research on trunk sap flow of typical artificial forests in the South Asian tropics on a 30 meter sample plot. This dataset contains a total of 1 Excel file, consisting of 24-hour dynamic monitoring data of dominant South Asian tropical tree species Red Spine and Pinus massoniana plantations from May 2020 to April 2021, with a total of 17184 records
