Spatiotemporal Patterns of Land Use Change and Ecosystem Service Value in Xianyang City
To grasp the spatiotemporal distribution characteristics of land use change and ecosys-tem service value in Xianyang City,and to reveal the changes in ecosystem service value,land use transfer matrix was used to analyze the land use change and evaluation of ecosystem service value was used to evaluate the ecosystem service value.The results show that:①The proportion of land use in de-scending order is cultivated land＞water area＞forest land＞construction land＞unused land;②The impact of human activities on land use is gradually deepening,and the utilization of forestland and construc-tion land is on the rise;③The land use change in Xianyang City mainly involves the transfer of arable land to construction land and the mutual transfer of arable land and forestland;④From 2003 to 2021,the value of ecosystem services in Xianyang City will increase by 323.1 million yuan,showing a trend of first increasing and then decreasing;⑤In addition to the continuous decreasing trend of supply ser-vice value,the value of regulating service,supporting service,and cultural service all show a trend of first increasing and then decreasing.The results can provide a basis for optimizing land use structure and layout,coordinating the relationship between land migration and ecological environment.
