Changes of land use and ecosystem services value in Xunwu County from 1990 to 2020
It was of great significance to explore the characteristics of land use change in Xunwu County,Ganzhou City,Hubei Prov-ince,and its impact on ecosystem services value(ESV)in the long-term series to ensure the ecological security and improve the re-gional ecological environment in the Dongjiang Basin.Based on the land cover data from 1990 to 2020,the change of land use in Xun-wu County during this period was analyzed,and the ecosystem service value of Xunwu County was evaluated by using the equivalent factor method.The results showed that the main land use types in Xunwu County were forest land,followed by cultivated land,and the proportion of the two land use types in the total area of Xunwu County was more than 98.0%.From 1990 to 2020,the total area of forest land and grassland in Xunwu County showed a downward trend,the proportion of cultivated land increased year by year,and the area of farmland returned to forest and grassland was less than the area of cultivated land reclamation.From 1990 to 2020,the ecosystem service value of Xunwu County showed a downward trend,and the areas with low ESV values were mainly distributed in the southwest and central parts of the study area,while the areas with high ESV values were consistent with the distribution of forest land in the study area.
