Effects of land use change on the ecosystem service value – A case study of Jiulongjiangkou, Fujian, China, from 2013 to 2021

Abstract

Abstract In this study, we utilized the dynamic changes in land use and ecosystem service value to provide ecological security protection and realize the coordinated development of ecosystem service functions for the Jiulongjiangkou Wetland Reserve. We counted the land use changes and calculated the ecological service value of the Jiulongjiangkou by using eCognition 9.0, ArcMap 10.2, Fragstats 4.2, and other software based on the remote sensing image from 2013 to 2021 with five phases, which were captured by Landsat-8 satellite. The results showed that the land use type of Jiulongjiangkou City changed significantly and was affected by human activities, in which the wetland area decreased by 8.61 km2, a decrease of 8.5%. In the past ten years, the value of ecosystem service has not increased, which decreased by 1.3*108 RMB in 2021 compared with 2013. In the future, we should continue to increase the protection of forest lands and waters, maintain the stability of the ecosystem of protected areas, rationally plan the land for construction, actively develop green agriculture, and steadily enhance the value of ecosystem service.
