Abstract: By using landscape-level animal population simulator (LAPS), the spatiotemporal dynamics of the main prey populations of Panthera tigris from 1990 to 2009 in East Wanda Mountains were simulated, based on the different scenarios of accidental mortality and carrying capacity that could represent the influence of direct and indirect human disturbance. The effects of the accidental mortality and carrying capacity on the population dynamics were studied, and the spatiotemporal distribution of animal blocks was exhibited explicitly in the study area, with the individual density in different patches compared. The results showed that compared with carrying capacity, accidental mortality had more effects on prey populations, and the population density was significantly higher in shrubs than in broadleaved forests. The conclusions made in this study could provide scientific basis for the conservation and management of P. tigris’s preys in East Wanda Mountains, while the quantitative validation of the conclusions still needs further investigation.
