摘　　要：为进一步了解吉林珲春东北虎豹分布区国道(G331)对东北虎豹迁移的影响,运用电路理论及ArcGIS软件,根据东北虎豹栖息的生境类型划分生态源地,根据迁移特征选取土地利用、有蹄类距离和道路分布等8个主要阻力因子,通过专家打分法构建综合阻力面,利用廊道设计模型(Linkage Mapper),研究了东北虎豹核心栖息地间潜在的生态廊道情况.结果表明:珲春东北虎豹分布区内,东北虎豹潜在生境廊道12条、夹点6个、障碍点7个.在8个主要阻力因子中,土地利用类型、森林郁闭度、有蹄类距离和坡度对综合阻力面有较大影响.To further understanding the impact of the National Highway(G331)on the migration of Amur tiger(Panthera tigris altaica)and leopard(Panthera pardus orientalis)in Hunchun,theory of circuits and ArcGIS software were applied to delineate ecological source sites based on habitat types of the Amur tiger and leopard.Eight main resistance factors were selected according to migration characteristics,which including land use,hoofed species distance and road distribution.The comprehensive resistance surface was constructed by the expert scoring method,and the potential ecological corridors between the core habitats were obtained through the corridor design model(Linkage Mapper).The results identified 12 potential habitat corridors,6 pinch points and 7 barrier points.In eight main resistance factors,land use type,forest canopy density,hoofed species distance and slope to the comprehensive resistance surface have a great influence.
