Abstract：The spatiotemporal analysis of surface temperature using remote sensing technology is crucial for environmental monitoring and assessing climate change.This paper conducts a spatiotemporal analysis and exploration of surface temperature in the Huaihai Economic Zone based on MODIS data and geospatial autocorrelation analysis methods.The results show that from 2001 to 2020,the surface temperature in the Huaihai Economic Zone showed an overall upward trend;the average surface temperature over the years was 21.31℃,with high-temperature areas located in the southwestern part of Jining at the border with Heze,and low-temperature areas in the southern band of Jining as well as in Suqian and Xuzhou;the highest temperature recorded was 22.07℃in Huaibei City,while the lowest temperature was 19.92℃in Suqian City;the surface temperature in the Huaihai Economic Zone exhibits a high degree of aggregation,with a positive spatial correlation.This study provides a reference for the monitoring of resources and environment and the assessment of climate change.
