摘　　要：冷浸田地区因土壤发生层长期遭到地下水浸渍而导致作物减产明显。为研究冷浸田的成因及其地下水特征,选取江汉平原为研究区,以遥感影像、气象和近30年的典型冷浸田地区地下水水位监测数据为基础,采用空间分析和相关性分析等方法,研究江汉平原冷浸田的分布特征及影响因素、地下水水位埋深的时空变化规律和地下水环境特征。结果表明,2021年江汉平原冷浸田主要分布在监利、汉川、洪湖、仙桃、潜江等地区,分布范围相比20世纪80年代呈减少趋势;冷浸田的分布与潜水位埋深有着十分密切的联系,水位埋深较浅的地区容易诱发冷浸田;年内主汛期潜水水位埋深较浅,更易发生冷浸田现象;近30年来,冷浸田地区地下水水位埋深整体呈增大趋势;降雨是诱发冷浸田的重要影响因素;冷浸田分布地区的地下水处于强还原环境,铁、锰和硫化物等还原性物质易大量积累。Due to the long-term immersion of groundwater in the soil layer,the yield of crops in the cold-waterlogged paddy field area has been significantly reduced.In order to study the causes of the cold-waterlogged paddy field and its groundwater characteristics,this paper selects the Jianghan Plain as the research area.Based on remote sensing images,meteorology and groundwater level monitoring data of typical cold-waterlogged paddy fields in the past 30 years,the distribution characteristics and influencing factors of cold-waterlogged paddy fields in the Jianghan Plain,the temporal and spatial variation of groundwater depth and groundwater environment characteristics are studied by spatial analysis and correlation analysis.The results showed that the cold-waterlogged paddy fields in Jianghan Plain were mainly distributed in Jianli,Hanchuan,Honghu,Xiantao and Qianjiang,and the distribution range showed a decreasing trend compared with the 1980 s.The distribution of cold-waterlogged fields is closely related to the buried depth of groundwater level,and the areas with shallow water level are more likely to induce cold-waterlogged fields.The buried depth of groundwater level in the main flood season of the study area is relatively shallow,and the phenomenon of cold waterlogged paddy field is more libely to occur.In the past 30 years,the buried depth of groundwater level in the cold waterlogged field area has shown an overall increasing trend,and rainfall is an important factor inducing cold waterlogged field.The groundwater in the distribution area of cold waterlogged paddy field is in a strong reducing environment,and the reducing substances such as iron,manganese and sulfide are easy to accumulate in large quantities.
