Soil temperature reflects the impact of local factors, such as the vegetation, soil, and atmosphere of a region.
Therefore, it is important to understand the regional variation of soil temperature.
However, given the lack of observations with adequate spatial and/or temporal coverage, it is often difficult to use observational data to study the regional variation.
Based on the observational data from Nanchang and Ganzhou stations and ERA-Interim/Land reanalysis data, this study analyzed the spatiotemporal distribution characteristics of soil temperature over Poyang Lake Basin.
Four soil depths were examined, 0–7, 7–28, 28–100, and 100–289 cm, recorded as ST1, ST2, ST3, and ST4, respectively.
The results showed close correlations between observation data and reanalysis data at different depths.
Reanalysis data could reproduce the main spatiotemporal distributions of soil temperature over the Poyang Lake Basin but generally underestimated their magnitudes.
Temporally, there was a clear warming trend in the basin.
Seasonally, the temperature increase was the most rapid in spring and the slowest in summer, except for ST4, which increased the fastest in spring and the slowest in winter.
The temperature increase was faster for ST1 than the other depths.
The warming trend was almost the same for ST2, ST3, and ST4.
An abrupt change of annual soil temperature at all depths occurred in 1997, and annual soil temperatures at all depths were abnormally low in 1984.
Spatially, annual soil temperature decreased with latitude, except for the summer ST1.
Because of the high temperature and precipitation in summer, the ST1 values were higher around the lake and the river.
The climatic trend of soil temperature generally increased from south to north, which was opposite to the distribution of soil temperature.
These findings provide a basis for understanding and assessing the variation of soil temperature in the Poyang Lake Basin.
