摘　　要：陆地生态系统年总初级生产力(AGPP)是粮食生产和陆地生态系统固碳的基础。分析AGPP的时空变化可以为保障区域粮食安全和减缓气候变化趋势提供理论依据,但需以准确评估区域AGPP为基础。基于ChinaFLUX的长期联网观测数据和公开的数据集,本研究构建了中国陆地生态系统AGPP数据集,并结合生物、气候和土壤因素,利用随机森林回归树通过模拟单位叶面积的AGPP构建了中国AGPP评估模型,生成了2000–2020年中国陆地生态系统AGPP数据,空间分辨率为30arcsecond,数据格式为tiff。本数据可以为模型模拟提供验证数据,也可以为区域生产力、生态质量、陆地碳汇评估及管理提供数据支撑。The annual gross primary productivity(AGPP)is the basis of food production and carbon sequestration in terrestrial ecosystems.An accurate assessment of regional AGPP can provide a theoretical basis for analyzing the spatiotemporal variation of AGPP and ensuring regional food security and mitigating climate change trends.Based on Chinese Flux Observation and Research Network(ChinaFLUX)measurements and public datasets,we produced a dataset of annual gross primary productivity over China’s terrestrial ecosystems was constructed.In combination with biological,climatic,and soil factors,we used the random forest regression tree to construct the assessment model of China AGPP by simulating the AGPP of unit leaf area.The dataset of annual gross primary productivity over China’s terrestrial ecosystems during 2000-2020 was generated with a spatial resolution of 30arcsecond and a data format of tiff.The dataset can provide validation data for model simulation,as well as data support for regional productivity,ecological quality,and assessment and management of terrestrial carbon sinks.
