Spatiotemporal changes in recreation potential of ecosystem services in Sanjiangyuan, China

Based on the theory of recreational experience and landscape character classification systems, we propose that recreation potential includes aesthetic service potential and suitable environment provision potential. These two potentials are determined by landscape features including topography, land cover, vegetation and climate. Taking Sanjiangyuan as an example, we analyse spatiotemporal changes in both potentials from 1978 to 2012. In Sanjiangyuan, aesthetic quality has deteriorated, but the recreational environment has become more suitable owing to climate change. These changes may decrease ecotourism and increase mass tourism, which would further increase pressure on the environment.
