Landscape connectivity has important consequences for conservation of ecosystem services, gene flow, and landscape planning. In this study, the connectivity between the habitat patches occupied by the Yunnan snub-nosed monkey was analyzed based on circuit theory. In areas with more contiguous habitat, the key conservation and restoration areas have been identified as "stepping stones". On the other hand, in areas where habitat contiguity is low, the key protection and restoration areas for corridor construction have been determined by using the connectivity model of circuit theory. In this study, the results indicated that:the connectivity of each intra-regional monkey groups was superior. Areas in the middle showed the best connectivity, followed by those in the north, while the worst areas were distributed in the south. The habitat patches G3 and G4 in the north were identified as "stepping stones" and play a pivotal role in connecting the monkey habitat patches that are key areas for conservation and restoration. At the same time, the protection and restoration of vegetation between the southern and central monkey habitats is particularly important for gene exchange to avoid inbreeding depression and the long term survival of the southern population of Yunnan snub nosed monkey. Compared with the single path obtained by graph theory, the multipath obtained by circuit theory is more realistic. The methods followed in this study and our findings provide an effective scientific basis for a regional ecological corridor design for the protection of this endangered species.
