摘　　要：土壤水分是分析陆地水资源形成、转化、消耗等过程的重要媒介,也是评价耕作及灌溉制度是否合理的重要依据,对分析土壤盐分含量变化趋势及农田水质状况有着重要作用。河南商丘农田生态系统国家野外科学观测研究站(简称商丘站)位于黄淮海平原核心地带(由黄河冲积而形成的平原地貌),在土壤含水量长期观测工作中,严格执行《陆地生态系统土壤观测指标与规范》中各项技术规范及操作规程,确保相关人员流程的规范性,从而实现数据质量在连续性、完整性、准确性、可比性方面达到要求。本数据集收集、整理涉及商丘站2008-2020年6处典型农田耕地的不同深度土层(0-10cm、10-20cm、20-40cm、40-60cm、60-80cm及80-100cm)土壤含水量数据。本数据集可为豫东旱、涝、盐、碱及轮作模式耗水规律等技术问题的研究提供数据支撑,并为区域内耕作、施肥及灌溉制度的确立提供更为合理的科学依据。Soil moisture serves as a crucial medium for analyzing the intricate processes involved in the formation,transformation,and consumption of land-water resources.It also holds significant value as a foundation for evaluating the effectiveness of cultivation and irrigation systems and plays a pivotal role in analyzing soil salinity trends and farmland water quality.The National Agricultural Experimental Station for Agricultural Environment in Shangqiu,Henan Province(referred to as Shangqiu Station)is situated in the core area of the Huanghuaihai Plain(a plain formed by the alluvial deposition of the Yellow River).In the long-term observation of soil water content,it strictly follows the technical specifications and operating procedures in the Protocols for Standard Soil Observation and Measurement in Terrestrial Ecosystems to ensure the standardization of relevant personnel processes,thereby achieving the required data quality in terms of continuity,completeness,accuracy,and comparability.This comprehensive dataset gathers and organizes data on the water content of soil at varying depths(0-10 cm,10-20 cm,20-40 cm,40-60 cm,60-80 cm,and 80-100 cm)from six representative farmland sites at Shangqiu Station from 2008 to 2020.This invaluable resource furnishes crucial data support for addressing technical challenges related to drought,flooding,soil salinity,alkalinity,and water consumption patterns in crop rotations in Eastern Henan,thereby strengthening the scientific basis for developing cultivation,fertilization,and irrigation systems in the region.
