基于MaxEnt模型和ArcGIS预测南京市人与野猪冲突的空间分布

[Objective]To predict the spatial distribution of conflicts between humans and wild boars in Nanjing,classify different risk levels,establish an emergency prevention mechanism for wild boars,and provide data support for wildlife damage compensation,damage insurance and differential premium policies.[Method]86 effective distribution sites of wild boar conflict were obtained by setting up infrared cameras,questionnaire survey and data collection.MaxEnt model and ArcGIS were used to analyze and predict the potential distribution area of human-wild boar conflict in Nanjing.[Result]The high-risk areas of human-wild boar conflict in Nanjing were concentrated in the surrounding areas such as Lishui Wuxiang Mountain,Jiangning Tangshan Mountain and Pukou Laoshan Mountain.The high-risk area was 266.69 km2,accounting for 4.05%of the total area of the city.The risk of wild boar damage faced by forest land and surrounding residents was relatively high.The medium risk area was 982.78 km2,mainly distributed in the periphery of forest land,accounting for 14.92%of the city area.The area of low risk area is 5337.50 km2,which is mainly away from the mountainous area and forest land,accounting for 81.03%of the city area.[Conclusion]The contribution rate of environmental factors such as distance from forest land,altitude and precipitation in the driest quarter to the prediction model was higher,indicating that the distribution of human-wild boar conflict risk areas was related to environmental factors such as forest land,altitude and precipitation.The regional characteristics of the conflict distribution area between human and wild boar in Nanjing are obvious.
