摘　　要：中国科学院新疆策勒荒漠草地生态系统国家野外科学观测研究站(以下简称“策勒站”)地处塔里木盆地南缘,南依昆仑山,北临我国最大的塔克拉玛干沙漠。具有植被群落简单,土壤有机质积累缓慢等特点。凋落物是该区域重要的养分来源。基于对策勒站荒漠植物群落的长期定位观测,通过对不同植物凋落物器官(枝、叶、果)分组,本文整理统计得到2010–2020年塔里木盆地南部荒漠草地凋落物的回收量月动态数据,同时记载了观测场群落以及土壤养分的年度变化情况。数据的产生严格遵照CERN生物观测规范执行,数据的审核及质量控制由台站与分中心质控人员共同完成。本数据集以期为深入研究塔里木盆地南部荒漠草地凋落物动态变化提供基础数据,为了解和评估极端干旱荒漠生态系统养分循环过程提供理论支撑。The Cele National Field Science Observation and Research Station of Desert Grassland Ecosystem of Xinjiang of Chinese Academy of Science(Hereinafter referred to as"Cele Station"),is located on the southern margin of the Tarim Basin bordered to the south by the Kunlun Mountains and to the north by the largest desert in China,the Taklimakan Desert.As a result of simple vegetation community and slow accumulation of soil organic matter,litter serves as an important source of nutrients in this area.Based on the long-term observations of desert plant communities at Cele station,we gathered monthly dynamic data of litter recovery in the desert grassland from Southern Tarim Basin from 2010 to 2020.Based on plant organs(branches,leaves,and fruits),the monthly dynamic data of litter recovery at the observation sites and plots were sorted out,and the annual changes of community and soil nutrients were recorded.Data were compiled in strict accordance with CERN bio-observation specifications.The data has undergone review and quality control by the quality control personnel of the station and sub-center.The results would provide basic data for further study of litter dynamics in the desert grassland from Southern Tarim Basin,and theoretical support for better understanding and assessing nutrient cycling in hyper–arid desert ecosystems.
