摘要：本研究依托崇左凭祥友谊关森林生态系统广西野外科学观测研究站,于2020年5月至2021年4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红椎(Castanopsis hystrix Miq.)和马尾松(Pinus massoniana Lamb.)为研究对象,利用TDP(The thermal dissipation)热扩散探针技术,开展南亚热带典型人工林树干液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、马尾松树干液流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。
This study was conducted from May 2020 to April 2021 at the Tropical Forestry Experimental Center of the Chinese Academy of Forestry in Youyiguan Pingxiang Chongzuo Forest Ecosystem Observation and Research Station of Guangxi,with the dominant tree species of the southern subtropical Castanopsis hystrix and Pinus massoniana plantations as the research objects.We used the thermal dissipation probe(TDP)technique to monitor and study the continuous dynamics of sap flow in the trunk of typical plantation forests in southern subtropics.The sample plots were set up and monitored pursuant to relevant specifications.In this study,we analyzed and processed data to calculate the 24-hour measured data of trunk sap flow of red spines and horsetail pines.Moreover,an explanation of the data construction is also available.The establishment and sharing of this dataset can provide basic data for in-depth research on scientific issues such as forest water use patterns and their response to global climate change.This dataset can serve as a scientific reference for sustainable development and management of forest ecosystems in south subtropical zones.
