广东省古田省级自然保护区野猪种群密度研究

Estimation of the Population Density of Wild Boar(Sus Scrofa)in Gutian Provincial Nature Reserve in Guangdong province Based on Infrared Camera Data

基于惠东古田省级自然保护区公里网格化红外相机监测数据,运用随机相遇模型对保护区内的野猪种群密度进行了估算,结果显示保护区内野猪主要分布于东北部,种群密度为4.97头·km^(-2),种群数量约为109头。其中核心区野猪种群密度为4.95头·km^(-2),种群数量约为69头;缓冲区野猪种群密度最大,为5.31头·km^(-2),种群数量约为37头;实验区野猪种群密度为2.36头·km^(-2),种群数量约为3头。本研究结果显示保护区内野猪密度相比2020年有所增加,提示应采取一定的控制措施。

Wildlife survey in Gutian Provincial Nature Reserve in Huidong County was conducted by infrared camera monitoring,and the density of wild boar(Sus scrofa)was estimated using Random Encounter Model based on camera trapping data.Results showed that wild boars are mainly distributed in the northeast of the reserve.Its population density is about 4.97·km^(-2)and the estimated population is 109.The density in core zone is 4.95·km^(-2)with an estimated population of 37.The density in buffer zone is 5.31·km^(-2)with an estimated population of 69,which accounts for the highest density.The density in experimental zone is 2.36·km^(-2)with an estimated population of 3.It is concluded that the population of wild boar has increased since 2020,indicating that certain control measures should be taken.
