Characteristics of Soil Temperature Variation in Jiangxi Province and Its Relationship with Meteorological Elements
Understanding the influencing factors,depth variation,seasonal variation and regional differences of soil temperature in Jiangxi Province can provide research basis for soil physical and chemical properties,soil biological distribution,growth and development.It provides scientific reference for agricultural planting and ecological construction.Based on the monthly average data of soil temperature,air temperature,precipitation,sunshine and relative humidity in each layer of ground meteorological data from 2005 to 2020,this study analyzed the seasonal variation of soil temperature in each layer of Jiangxi Province,the relationship between soil temperature and depth and its regional difference characteristics,and summarized the influence of various meteorological elements on soil temperature in each layer.The results showed that the seasonal variation of soil temperature in different layers in Jiangxi Province was very obvious.The hysteresis of soil temperature change became more obvious with the increase of soil depth.In spring and summer,the soil temperature decreased with the increase of soil depth,but the temperature variation decreased.Soil temperature increased with soil depth in autumn and winter,and the temperature changed greatly.The seasonal variation of soil temperature was different among different regions,and there was a quadratic linear relationship between soil temperature and depth.There were obvious differences in the correlation between soil temperature and meteorological elements in different regions.Single meteorological element had little influence on soil temperature and temperature,while the interaction of multiple meteorological elements had more obvious influence on soil temperature.
