摘　　要：土壤水是地球水体的重要组成部分之一,陆地上植被和作物所利用的水分主要是从土壤中直接汲取的。因此土壤水的存贮、补给、消耗、更新和平衡对全国尤其是干旱半干旱区域的农业、牧业、林业、自然生态环境和水资源平衡,有着极其重要的意义。本数据集选取中国生态系统研究网络(CERN)位于中国西北干旱半干旱区的8个生态系统观测研究站,收集整理了各站2005–2017年的土壤含水量长期观测数据,通过质量控制、开展剖面-样地尺度上层次及时间归一化统计计算,生成了相应的土壤储水量数据集,以期为中国干旱半干旱区典型生态系统土壤储水量分布及变化状况提供长时序的数据刻画和支撑。Soil water is one of the important components of the earth's water resources,and serves as the source of water directly consumed by terrestrial vegetation and crops.Therefore,the storage,recharge,consumption,renewal and balance of soil water are of great significance to agriculture,husbandry,forestry,ecological environment and water resources balance,especially for the arid and semi-arid areas in China.We collected and sorted out the long-term observation data of soil moisture from eight ecosystem observation and research stations of the Chinese Ecosystem Research Network(CERN)located in the arid and semi-arid areas in China during 2005-2017.On this basis,we produced the corresponding soil water storage dataset through quality control,spatial and temporal normalization,statistical calculation.This dataset is expected to provide long-term data support for understanding distribution and change of soil water storage in typical ecosystems in arid and semi-arid areas in China.
