In order to reveal the impact of land use transition on the ecosystem service function of urban agglomeration, central Yunnan was the focus of research. Based on the three-phase Landsat TM/OLI remote sensing interpretation data in 2000, 2010 and 2020, the dynamic change model of land use, the ecosystem service value calculation model and the ecological contribution of land use transformation explores the temporal and spatial evolution characteristics of different land use transformation processes and ecosystem service value. It also combines the cross-sensitivity coefficient model to quantitatively evaluate the response degree and direction of land use transformation to ecosystem service value and delineate the sensitivity partition. The results show that:(1)the land use types of urban agglomerations in central Yunnan are mainly forestland, grassland and cultivated land. While the construction land continues to expand, the area of cultivated land, water area and unused land continues to decrease, the grassland and forest land have also experienced a process of change, first decreasing and then increasing;(2)during the study period, the ecosystem service value showed a trend of first decreasing and then increasing, the high value areas of average ecosystem service value were mainly distributed in the three plateau lake basins of Dianchi Lake, Fuxian Lake and Xingyun Lake;(3)in the past 20 years, returning farmland to forests, grasses, and lakes have contributed 49.10% to the improvement of ecosystem services, deforestation and reclamation of land and reclaiming land from lakes have taken up woodland, grassland and waters, resulting in a reduction of the ecosystem service value by approximately 265 million yuan;(4)the transformation of cultivated land, forest land, grassland and water area to other land types is sensitive to the value of ecological services. The highly ecologically sensitive areas of transformation between cultivated land, forest land, grassland and construction land are concentrated in Qujing and Chuxiong, the highly ecologically sensitive areas of transformation between cultivated land and forest land are less distributed, and the lower ecologically sensitive areas of transformation from forest land to grassland and water area are the most widely distributed. Different land use transitions in the study area were significant on ecosystem service function.
