Abstract: To understand the activity patterns of dominant mammal species in the Luofushan Provincial Nature Reserve, and to promote a better understanding of animal survival strategies, thereby providing more scientific conservation measures for wildlife, from June 2022 to June 2024, 29 infrared cameras were set up in Luofu Mountain Reserve for animal monitoring, and a total of 3883 effective photos were taken, including 640 independent effective photos. The relative abundance, annual activity pattern, seasonal difference of circadian rhythm and diurnal activity of four dominant species of Sus scrofa, Melogale moschata, Hystrix hodgsoni and Muntiacus reevesi were analyzed. The results showed that: (1) the site occupancy ranked from high to low as M. moschata= S. scrofa > H. hodgsoni > M. reevesi, and the relative abundance ranked from high to low as S. scrofa > M. moschata > H. hodgsoni >M. reevesi; (2) the annual activity patterns of S. scrofa, M. moschata and H. hodgsoni were similar on the whole, with higher abundance in summer and autumn and lower abundance in winter and spring. M. reevesi has activity in all seasons, with the highest abundance in January; (3) S. scrofa has two activity peaks in the morning and afternoon, and the activity is concentrated from 8:00 to 10:00 and from 14:00 to 18:00 in the afternoon, the activity time of M. moschata is from 18:00 to 6:00 the next day, and the relative richness of 22:00-24:00 in summer is significantly higher than that of other seasons, the activity time of H. hodgsoni is from 18:00 to 6:00 the next day, the activity of M. reevesi showed bimodal characteristics in different seasons, but the time of morning peak and evening peak were different; (4) S. scrofa is a typical diurnal animal, the activities of M. reevesi have no obvious difference between day and night, and M. moschata and H. hodgsoni are typical nocturnal species.
