A dataset of soil water and heat dynamics from Pinus massoniana plantations under close-to-nature management in South Subtropics (2016–2021)

Abstract

This study was conducted at the Tropical Forestry Experimental Center of the Chinese Academy of Forestry in Youyiguan Pingxiang Chongzuo Forest Ecosystem Observation and Research Station of Guangxi. Based on the automatic meteorological observation station, we monitored and analyzed the soil hydrothermal dynamics in Pinus massoniana plantations under close-to-nature management. The sample plots layout, index monitoring, and data quality control were carried out in accordance with relevant specifications. This dataset contains the data of soil temperature, soil volume water content, soil heat flux, as well as air temperature and air humidity in Pinus massoniana plantations of close-to-nature management in South Subtropics from 2016 to 2021. After standard data processing, including outlier elimination and data interpolation, we statistically derived the daily data of soil water and heat dynamics of Pinus massoniana, and explained the construction of the dataset. The establishment and sharing of this dataset are valuable for facilitating a comprehensive understanding of the characteristics of soil water and heat in Pinus massoniana plantations under close-to-nature management in South Subtropics. Furthermore, the dataset can serve as an important resource for in-depth research on the response of mixed coniferous broad-leaved forest to global climate change. It can provide essential to support the sustainable management and conservation of forest resources in South Subtropics.
