Application of ecosystem service flows model in water security assessment: A case study in Weihe River Basin, China

Assessing water resource security is vital for the environment development. However, most studies only focus on the static water security status of the region, ignored the spatial flows of ecosystem services. Whereas by integrating the ecosystem services flows model into water security simulation, t...
