This study applied Landsat images of 2008 and 2016 to study land use pattern in the dry?hot valley region (Yuanmou, Yunnan). Land use information was visually interpreted from the images. We further assessed the static and dynamic values of regional ecosystem services, and analyzed impacting factors for the changes of ecosystem services. Results showed that the area of cropland, forested land and built-up had increased, and the area of grassland, unutilized land and water area had decreased. In 2008 and 2016, the total static values of regional ecosystem services were 2.598 and 2.654 billion Yuan respectively. The total dynamic values of regional ecosystem services were 0.918 and 1.600 billion Yuan, respectively. Although the total dynamic values of ecosystem services were accounted for only 35.40% and 60.30% of the total static values of ecosystem services respectively in the same period, the growth rate of the total dynamic value had increased by 74.01%, significantly higher than that of the total static value (2.27%). The ecosystem service values of soil formation and conservation in 2008 and 2016 were 491 and 503 million Yuan, the highest of all the individual static ecosystem services. Agricultural economic development, urban expansion and population growth caused the expansion of cropland and built-up. Soil conservation and integrated ecological management had contributed to the area restoration of forest. Significant improvements in affordability and willingness to pay dramatically accelerated the growth of the total dynamic value of ecosystem services. Therefore, we should strengthen regulation of regional land use, and continue to implement ecological control measures such as soil conservation, Green for Green to maintain regional ecosystem function for achieving regional sustainable development in the dry?hot valley region.
