Table 4 SPANs model conceptual framework localization.
From: Coupling process of carbon sink service flow based on metacoupling framework
SPANs concept | SPANs concept interpretation | SPANs model | Localization concept | Localization model |
|---|---|---|---|---|
Ecosystem service flows | The spatial flow path of ecosystem services from supply to use. | Quantization and spatial mapping through SPANs model flow module. | CSSF from generation to consumption. | CSSF is the spatial and temporal connections of service flows from the supply area to the demand area, which are process descriptions of service flow paths. |
“Source” area | Position of the supply service. | “Source” generates carrier agents for subsequent flow simulations. | CSS supply area location. | The supply level and location of CSS are calculated based on the empirical model. |
“Use” area | Position of beneficiary. | Passing through the carrier results in a traffic loss and affects the supply services the user receives. | CSS demand area location. | Identify the demand and location of carbon sequestration services in conjunction with population distribution and energy consumption needs. |
“Sink” area | Carrier region of the service delivery process. | Including beneficial and harmful vectors. | Potential demand area and potential supply area of CSSF. | Application and land use change and land use respiratory CE70 represent the loss of the CSSF process. |
Mapping of flows | Overlap of source and use regions. | Calculated directly from the SPANs model. | In situ service flow. | Coupled SPANs-BBNs model simulates the probability distribution of supply and demand conditions for CSS. |
