    Abstract:
    The compatible conservation of ecosystem services (ES) refers to the sustainable development of a region and the multiple dimensions of the region population's well-being. Applying the ES relationship to systematic conservation planning (SCP) can help determine the protection priorities associated with ES and support good zoning decisions. This study uses Nanchang, China as a case study to construct a multi-scenario ES protection scheme. This includes evaluating the spatial distribution characteristics of four core ES, and the ES relationships in the subregion in Nanchang. The ES relationship is then used to construct three ES conservation scenarios (synergetic, trade-off and incompatible), and the SCP tool is used for zoning. The results show the following. First, the incompatible scenario prioritizes the conservation of supporting services and provisioning services, which support ecological protection and cultivated land security. Second, given a land management and control threshold, the management zones can be compatible with a large proportion of secondary services in the synergetic scenario (22%). Fewer secondary services are compatible under the trade-off scenario (8%). As the compatible secondary service targets increase, each management zone area experiences a nonlinear change. The spatial change is more stable in the synergetic scenario compared to the trade-off scenario, and the space of management zone becomes discrete under the trade-off scenario. Third, the compatibility process has a feedback effect on the ES relationship. Compared with the trade-off scenario, compatible synergetic services are more stable with respect to changes in the ES relationship. Constructing ecological buffer zones takes up cultivated land, decreasing the synergy between carbon sequestration services and food production services. However, ecological buffer zones should play a role in certain areas. The compatibility of increased food production services and habitat services in priority conservation and controlled development zones enhance ES trade-offs. An increase in cultural services is compatible with carbon sequestration services in the ecological buffer zone. This changes the relationship between ES, from having a weak trade-off to having a weak synergy. Creating a compatible ES is a spatial trade-off process; these synergies and trade-offs should be considered in spatial planning. An appropriate proportion of ES should be allocated to each zone, to increase the coordinated management of the urban-rural ecology.
