2010-2020年塔里木盆地南部荒漠草地凋落物回收量月动态数据集

Cele National Field Science Observation and Research Station of Desert Grassland Ecosystem of Xinjiang (Cele Station), Chinese Academy of Science, is located in the southern margin of Tarim Basin, south by Kunlun Mountains, north by the largest Taklimakan desert in our country. With the characteristics of simple vegetation community and slow accumulation of soil organic matter, litter is an important source of nutrients in this area. Based on the long-term observation of desert plant communities in Cele station, we collected the monthly dynamic data of litter recovery in desert grassland from the southern Tarim Basin during 2010 to 2020. By grouping plant organs (branches, leaves, and fruits), the monthly dynamic data of litter recovery in the observation site and plot were sorted out, and the annual changes of community and soil nutrients were recorded. Data were generated in strict accordance with CERN bio-observation specifications. Data review and quality control were completed by the quality control personnel of the station and sub-center. Our results would provide basic data for further study of litter dynamics in desert grassland from southern Tarim Basin, and theoretical support for understanding and assessing nutrient cycling in hyper–arid desert ecosystems.

中国科学院新疆荒漠草原生态系统策勒国家野外科学观测研究站（Cele Station，以下简称策勒站）地处塔里木盆地南缘，南靠昆仑山脉，北接我国最大的塔克拉玛干沙漠。该区域植被群落结构简单，土壤有机质积累缓慢，枯落物是当地重要的养分来源。依托策勒站长期开展的荒漠植物群落观测工作，研究团队收集了2010至2020年塔里木盆地南缘荒漠草原枯落物归还的月动态数据。研究团队按植物器官（枝、叶、果实）对观测样地与样方内的枯落物归还月动态数据进行整理，并记录了群落与土壤养分的年际变化。所有数据均严格遵循中国生态系统研究网络（CERN）生物观测规范生成。数据审核与质量控制工作由策勒站及分中心的质控人员完成。本数据集可为塔里木盆地南缘荒漠草原枯落物动态的后续研究提供基础数据，同时为理解与评估极端干旱荒漠生态系统的养分循环提供理论支撑。
