The results showed that in terms of village landscape
value (VL), the seven types of riparian zones exhibited
higher supply efficiency. R1–R5 riparian zones showed
weak supply in regulating services. In addition, the supply
efficiency of the seven types of riparian zones exhibited
differentiated results, where the riparian zone at the
boundary of residential areas (R1) exhibited weak supply
in agricultural product output, the riparian zone at the
boundary of industrial land (R2) showed weak supply
in biodiversity, the riparian zone at the boundary of
agricultural land (R3) showed weak supply in all three types
of regulating services, the riparian zone at the boundary
of ponds (R4) exhibited weak supply in agricultural
product output (AP), biodiversity (BD), runoff regulation
