Abstract—

Changes in the distribution of broadleaf tree species—Tilia cordata Mill., Quercus robur L., Acer platanoides L., and Ulmus glabra Huds.—in the central part of the Southern Urals after the cessation of the period with extremely cold winters in the late 1970s have been analyzed using thematic maps of their distribution in the study region, which were created in the 1970s and early 21th century based on cartographic forest inventory materials. Abnormal winter temperatures had the greatest effect on the distribution of A. platanoides and U. glabra. All broadleaf species are currently expanding their range, with their distribution boundary shifting eastward, to the left bank of the Belaya River.

摘要—

在阔叶树物种分布的变化小叶椴厂，夏栎属，挪威枫L.，和榆茯苓Huds.，在乌拉尔南部的周期停止在极其寒冷的冬天后，中心部分使用研究区域分布的专题图对1970年代后期进行了分析，这些专题图是根据制图森林清单材料在1970年代和21世纪初创建的。冬季温度异常对白灵芝和无毛U. glabra的分布影响最大。目前，所有阔叶树种的范围都在扩大，其分布边界向东转移到了贝拉亚河的左岸。
