- Abstract:

In order to study the impact of land use on ecological service value(ESV), based on the land use and socioeconomic data of Chinese prefecture level cities from 1990 to 2018, the temporal and spatial differentiation characteristics of land use and ESV in the study area were studied by using the methods of land use dynamics, ESV evaluation model, sensitivity index and spatial autocorrelation, and the relationship between ESV and comprehensive land use dynamics spatial correlation of socio-economic indicators were analyzed. The results showed that: on the whole, except for the decrease of grassland area, other land use types increased, the dynamic degree of each land use type was significantly different, and the dynamic degree of comprehensive land use increased over the years; during the study period, ESV generally showed a decreasing trend, and the sensitivity indexes of ecological service values of different land types had been shown as <1; during the study period, the change of ecological service value was negatively correlated with the dynamic degree of comprehensive land use; the spatial characteristics of bivariate LISA map of ecological service value and comprehensive value of socio-economic indicators in each year were relatively consistent; the low—high type mainly distributed in the middle and eastern regions with rapid economic development, while the high—low type mainly distributed in the western regions with extensive grassland area and relatively backward economic development. Different land types and socioeconomic factors have different effects on ESV in different regions, which can provide more scientific decision-making services for promoting regional environmental protection and sustainable economic development in China.
