摘要:
通过研究自然条件下的江苏省土壤墒情时空变化规律，为防旱减灾、水利规划建设和区域水资源开发与管理等工作提供科学依据。根据江苏省2016—2022年的土壤墒情数据，并结合土壤物理特性和降水、蒸发等的影响，从不同角度分析了江苏省土壤墒情的变化规律。结果表明：空间上，多年平均情况下江苏省土壤墒情总体呈由苏北向苏南递增趋势；土壤含水量的年际变化受降水和蒸发因素影响明显，与降水量呈正相关关系，与蒸发量呈负相关关系；土壤墒情年内变化大致可分为稳定期、大量消耗期、快速恢复期和缓慢消耗期等4个时期。
Abstract:
By studying the spatiotemporal variation law of soil moisture in Jiangsu province under natural conditions, it can provide scientific basis for drought prevention and disaster reduction, water conservancy planning and construction, and regional water resources development and management. Based on the data of soil moisture in Jiangsu Province from 2016 to 2022, combined with the effects of soil physical characteristics, precipitation and evaporation, the change law of soil moisture in Jiangsu Province was analyzed from different perspectives. The results indicate that: Spatially, the soil moisture content in Jiangsu Province has been increasing from north to south of Jiangsu Province on average for many years; The inter-annual variation of soil water content was obviously affected by precipitation and evaporation factors, and was positively correlated with precipitation and negatively correlated with evaporation; The annual variation of soil moisture can be roughly divided into four periods: stable period, large consumption period, rapid recovery period and slow consumption period.
