摘　　要：受气候变化和人类活动的影响,湿地景观连通性不断发生变化.本文基于GIS技术、景观格局指数及灰色关联度等方法,探究了湿地景观连通性的影响机制.结果表明:吉林省西部地区湿地面积在1980—2020年减少了970.44 km2,湿地斑块形状指数值降低了1.766 8;吉林省西部湿地景观整体连通性指数增加了0.060 9,在湿地景观格局对连通性的影响因素中,湿地面积>湿地形状类指标>湿地分布类指标>湿地破碎度.Wetland landscape connectivity is constantly changing due to the impacts of climate change and human activities.This study explored the driving factors of wetland landscape connectivity based on GIS technology,landscape pattern index and gray correlation degree.The results showed that the wetland area in western Jilin Province decreased by 970.44 km 2 during 1980—2020,and the value of wetland patch shape index decreased by 1.7668.The overall connectivity index of wetland landscape increased by 0.0609.The driving factors of wetland landscape pattern on connectivity were ranked as followed:wetland area>wetland shape class index>wetland distribution class index>wetland fragmentation.
