Simulation study on water yield service flow based on the InVEST-Geoda-Gephi network: A case study on Wuyi Mountains, China

A study on the Wuyi Mountains, China, reveals significant spatial heterogeneity and mismatch between water yield service supply and demand from 2000 to 2020. The research found that high-supply areas often do not align with high-demand regions, particularly around provincial capitals and coastal economic zones. Urbanization and economic development have marginalized deficit nodes in the water yield service flow network, reducing its density and connectivity, thereby weakening the ecosystem's ability to provide water services. The study employed a novel methodology integrating InVEST, Geoda, and Gephi models to analyze spatiotemporal evolution, regional alignment patterns, and network characteristics of water yield service flows. This approach provides strategic insights for rational water resource allocation, ecological protection, and sustainable development in regional ecosystems.
