摘要
依托国家自然基金项目(41461112,31660235),在陇东黄土高原中沟小流域(35°19’N–35°20’N,107°30’E–107°31’E),选取20世纪70年代中后期大面积种植的人工刺槐林植被,根据热平衡原理,采用热扩散探针技术对所选样树的树干液流进行持续监测,并同时测定气象因子。该数据集包括:2017年5月19日–2019年12月10日陇东黄土高原中沟小流域常规样地树干液流监测数据(数据监测频率为10分钟),数据的存储形式为:.xlsx格式,压缩后数据量为6,59KB。该数据集部分数据(2017年生长季树干液流数据)的分析研究成果(甘肃泾川中沟小流域刺槐生长盛期树干液流动态分析与陇东黄土高原区人工刺槐林树干液流特征研究)已完成。
The artificial Robinia pseudoacacia plantation planted in the middle and late 1970 s was selected in the Zhonggou River basin(107°30’E-107°31’E,35°19’N-35°20’N) in the Loess Plateau of Gansu province.According to the principle of heat balance,the thermal diffusion probe technology was used to continuously monitor the trunk sap flow of the selected sample trees to obtain the in situ sample dataset of stem sap flow of Robinia pseudoacacia Plantation on the Loess Plateau.The dataset includes three tables:sap flow data of 8 Robinia pseudoacacia plantation in three periods,from May 19 to November 30 in 2017,April 24 to December 13 in 2018,January 13 to December 10 in 2019(Sap flow data were sampled every ten minutes).The dataset is archived in.xlsx data format in one file with data size of 6.59 MB.
