野猪危害风险的空间分布对野生动物栖息地管理具有重要意义。珲春是我国东北虎的重要活动区。野猪的危害给该地区东北虎的保护和管理带来了障碍。从家域和觅食地规模等方面预测了珲春市野猪危害风险的空间分布，探讨了老虎栖息地与野猪危害风险的空间相互作用。结果表明，距林缘距离是影响野猪危害的重要因素，38.68%的高风险区与虎栖息地重叠。因此，在野猪种群管理中应采取精准化、差异化的管理策略。珲春是我国东北虎的重要栖息地，也是野猪危害的典型地区。通过将最大熵模型中的家域尺度（12个变量）和饲养地尺度（10个变量）分别纳入22个变量，对中国东北地区野猪危害风险进行了预测，并分析了空间因素对野猪危害风险的影响。在靠近森林边缘的地区、森林覆盖率较高的地区、落叶林比例较低至中等的地区、道路密度低的地区、河流密度中等的地区和农田比例较高的地区，损害风险较高。被确定为高危害风险区的农田比例为23.55%，其中38.68%的农田位于东北虎栖息地范围内。最后，提出了基于不同管理目标的野猪危害预防措施。
Spatial distribution of wild boar damage risk is important and can be informative to wildlife habitat management. Hunchun is an important active area of Siberian tiger in China. The wild boar damage has brought barriers to the conservation and management of the Siberian tiger in this region. We predicted the spatial distribution of wild boar damage risk in Hunchun in terms of home range and feeding sites scales, and explored the spatial interaction between tiger habitats and the damage risk of wild boar. The results show the distance to the forest edge is an important factor affecting the wild boar damage, and 38.68% of the high-risk areas are overlapped with tiger habitats in Hunchun. Therefore, precise and differentiated management strategies should be adopted in the management of wild boar population. Hunchun, a typical area suffering wild boar (Sus scrofa) damage, is an important region for the Siberian Tiger (Panthera tigris) in China. By incorporating the maximum entropy model with 22 variables in the home range scale (12 variables) and in the feeding site scale (10 variables), we predicted wild boar damage risks in this area of China and analyzed how spatial factors influence damage risk. Damage risk was found to be high in areas close to the forest edge, areas with a higher forest cover and lower to medium deciduous forest proportion, low road density, and a medium river density and farmland proportion. The proportion of farmland which was identified as being in the high damage risk zone was 23.55%, of which 38.68% was within the habitat area of the Siberian Tiger. Finally, we propose wild boar damage prevention based on different management goals.
