Analysis of the Current Habitat Suitability of Chinese Serow in Anji County
[Objective]The Chinese Serow(Capricornis milneedwardsii),a nationally second-class protected wild animal.Evaluating the habitat suitability of the Chinese Serow in Anji County is of significant importance and value for its conservation within the county.[Method]Based on the 2020 Sentinel-2 remote sensing images,the land cover map of Anji County was generated through a random forest classification algorithm.This map was then combined with occurrence data of the Chinese Serow and environmental factors including climate,topography,vegetation and human disturbance,to assess the habitat suitability using the MaxEnt model.[Result]1)The areas suitable for Chinese Serow habitat in Anji County are concentrated in the southern region,covering relatively small areas.Regions with medium or higher suitability account for only 9.06％of the total area of the county,while 78.19％of the total area of the county is unsuitable for Chinese Serow habitat.2)The number and density of patches in areas with moderate or high suitability are relatively low,with an average fractal dimension of around 1.05 and a perimeter-area fractal dimension of less than 1.40,indicating that these areas are less affected by human interference.3)Compared with forests in areas with lower suitability levels,broad-leaved forests in moderate and higher suitability areas have a higher proportion,lower patch density,and landscape shape index,indicating that forests with higher suitability levels are less affected by human activities.[Conclusion]The study results shows that currently only a small area in the southern part of Anji County is suitable for the habitat of Chinese Serow,mainly due to the relatively low impact of human activities within the habitat.It should be continuously monitored and protected in the future.
