2023-02-22 A dataset of annual gross primary productivity over Chinese terrestrial ecosystems during 2000-2020 doi:10.57760/sciencedb.o00119.00077 en The dataset of annual gross primary productivity over Chinese terrestrial ecosystems was constructed based on Chinese Flux Observation and Research Network (ChinaFLUX) measurements and public datasets. Combined with biological, climatic, and soil factors, the random forest regression tree was used to construct the assessment model of China AGPP by simulating the AGPP of unit leaf area. The dataset of annual gross primary productivity over Chinese terrestrial ecosystems during 2000-2020 was generated with a spatial resolution of 30arcsecond and a data format of tiff. This data set includes one site observation AGPP data set and 21 regional AGPP data. The AGPP data set of site observation consists of 166 sites and 872 annual observation results, which is composed of 20 columns, including site name, ecosystem type, observation year, AGPP value, climate, and soil biological variables, references, etc. china; Annual gross primary productivity of terrestrial ecosystem; Random forest regression tree model; Spatiotemporal variation fan ren xue ZHU Xianjin CHEN Zhi YU Guirui ZHANG Weikang HAN Lang WANG Qiufeng CHEN Shiping LIU Shaomin WANG Huimin YAN Junhua TAN Junlei ZHANG Fawei ZHAO Fenghua LI Yingnian ZHANG Yiping SHI Peili ZHU Jiaojun WU Jiabing ZHAO Zhonghui HAO Yanbin SHA Liqing ZHANG Yucui JIANG Shicheng GU Fengxue WU Zhixiang ZHANG Yangjian ZHOU Li TANG Yakun JIA Bingrui LI Yuqiang SONG Qinghai DONG Gang GAO Yanhong JIANG Zhengde SUN Dan WANG Jianlin HE Qihua LI Xinhu WANG Fei WEI Wenxue DENG Zhengmiao HAO Xiangxiang LI Yan LIU Xiaoli ZHANG Xifeng ZHU Zhilin PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset http://www.doi.org/10.11922/11-6035.csd.2023.0037.zh Science Data Bank
