苏北地区土壤墒情时空变化规律研究

Spatial-Temporal Variation Patterns of Soil Moisture in the Northern Jiangsu Region

为研究自然条件下的苏北地区土壤墒情时空变化规律,本文选用苏北地区2016-2022年的土壤墒情数据,采用数理分析方法,从空间和时间角度分析了苏北地区土壤墒情的变化规律。结果表明,在相同土壤类型前提下,土壤含水量呈东南部高、西北部低的趋势,且不同深度土层土壤含水量相关关系显著;土壤墒情与降水量呈正相关关系,与蒸发量呈负相关关系。通过分析总结苏北地区土壤墒情变化规律,可为农业生产及水资源调配管理提供依据。

To study the spatial-temporal variation patterns of soil moisture in the northern Jiangsu region under natural conditions,this paper utilizes soil moisture data in northern Jiangsu from 2016 to 2022.Using mathematical analysis methods,the paper analyzes the changes in soil moisture from both spatial and temporal perspectives.The results indicate that,given the same soil type,soil moisture content shows a trend of being higher in the southeastern and lower in the northwestern,with a significant correlation between soil moisture content at different soil depths.Soil moisture is positively correlated with precipitation and negatively correlated with evaporation.By analyzing and summarizing the variation patterns of soil moisture in northern Jiangsu,this study provides a basis for agricultural production and water resource management.
