However, the changes of land use driven by human activities affect the provision of ecosystem services. Ecosystem services with different characteristics are affected by disparate spatial structure, type and patterns. Moreover, they have spatial autocorrelation that associated with their surroundings. In order to manage services by land use, clarify the circumstances of its ecosystem services and its spatial characteristics are required.
In this study, we assess four kinds of ecosystem services in Yunlin County with different periods by InVEST model and verify that ecosystem services have a positive spatial correlation. Furthermore, we analyze the distribution of hot and cold spot with local indicators of spatial association. The results showed that carbon storage, habitat quality and soil conservation reduce gradually with the change of land use. By setting simulated scenarios with different intensity of conservation zones, we found out under the enhance conservation scenarios, all services have a higher quality except water yield. The simulation also shows that it has a better effectiveness of maintenance and protection in the first class conservation zone.
Through the comparison of scenarios simulations, we can learn more about the impact and effectiveness of land use management strategies on ecosystem services. Moreover, we can weigh the pros and cons of different management strategies. Consequently, spatial association should be seriously consider in the assessment and spatialization of ecosystem services in order to analysis the distribute characteristics of services and its relationship with environment.
