[Objective] Based on the scale of network unit, the regional land use evolution and its ecosystem service value response characteristics from 1990 to 2019 were studied in order to provide decision-making basis for ecosystem protection and land spatial planning in rapid urbanization area represented by Gongyi City.[Methods] Based on the interpretation data of land use from 1990 to 2019 and the modified ESV equivalent at the grid scale, the ecosystem service value was estimated at Gongyi City, He'nan Province, and its spatial auto-correlation characteristics were discussed.[Results] ① During the study period, the growth rate of construction land in Gongyi City was the highest, on the contrary, the water area and shrubbery decreased significantly, with a decline of -45.17% and -10.09% respectively. In terms of land type transfer, the area of water and cultivated land was the most, and the main transfer out types were cultivated land and construction land. ② The value of ecosystem services showed a fluctuating downward trend, with a total decrease of 3.485 billion yuan in the past 30 years. Water area, arbor forest and cultivated land were the main components of ESV in Gongyi City. From the perspective of change characteristics, ESV in water area decreased significantly, with a total decrease of 3 554.9 million yuan. The regulation services dominated by hydrological regulation and climate regulation played a leading role in the composition of regional ESV, and its loss rate in the past 30 years was at a high level. ③ Spatial exploratory analysis showed that ESV had declined significantly in recent 30 years, and the negative effects of regional urbanization process on ecosystem were significant. The changes of high and low value areas of ESV in the north were mainly water area, cultivated land and construction land, while those in the south were mainly forestland and high coverage grassland, which were relatively stable. In 1990, the higher ESV areas were concentrated along the Yellow River, Yiluo River and Fuxi Mountain in the south, while the areas with lower ESV were mainly Gongyi City and the areas with relatively flat terrains in the east and the west. After 2000, the areas with higher ESV were rapidly reduced and mostly concentrated along the Yellow River. During 2000-2010, the low value ESV area in the main urban area gradually spread under the influence of rapid urban expansion. The low value concentration area of ESV had been formed in the urban area and the west and east oriented two belt areas of Gongyi City-Zhitian Town-Huiguo Town and Gongyi City-Zhulin Town-Mihe Town.[Conclusion] The expansion of construction land in Gongyi City is intensified, which leads to the continuous decline of regional ecosystem, and the spatial distribution is closely related to the development of human society and economy.
