Test and demonstration data set of automatic recording meter for tree diameter at breast height at field stations (2019-2020)

Test and demonstration data set of automatic recording meter for tree diameter at breast height at field stations (2019-2020)


We develop a DBH recording meter that can automatically record DBH at high frequencies and high precision in the field by designing a high-precision displacement sensor and temperature compensation algorithm. With the developed software, tree growth dynamics can be evaluated online in real time through remote computers or smartphones。The data set is collected through field test and demonstration at Qilian mountain station in Gansu Province and Beijing forest station by using the DBH recording meter. The data table includes the control values measured manually and the measured values of VI (displacement), RI (tree perimeter) and CI (tree diameter) collected by different tree species at different stations. The development of this automatic DBH recording meter promote the automation, intelligent level and independent innovation of vegetation ecological monitoring in China. The dynamic changes of DBH of trees serve the national ecosystem monitoring network, the construction of national "two screens and three belts" ecological security barrier and the demand for large-scale, all-weather and three-dimensional monitoring of vulnerable ecological areas. It plays an important supporting role in promoting the construction of ecological civilization in China.


File naming and required software

File naming: tree radial growth data is stored in numerical format. The file name is "tree radial data. Xlsx", which contains 14 sheets. Each sheet is named according to location + tree number to represent the value of a characteristic tree observed at a station. Data reading method: open it directly with Excel.
