It is of great significance to study the impact of land use intensity on ecosystem services for the scientific regulation of land use pattern and the promotion of ecological civilization construction. Based on the grid analysis and the remote sensing images of 2000, 2010 and 2018, this paper comprehensively uses InVEST, CASA model and bivariate spatial auto-correlation method to analyze the relationship between spatio-temporal evolution of Land Use Intensity(LUI)and three services of Food Production(FP), Habitat Quality(HQ) and Net Primary Productivity(NPP) in the part of Dongting Lake zone.
