摘要: 河北北部、内蒙古东部森林草原交错带的森林景观主要有白桦林、山杨林、云杉林、蒙古栎林和榆树疏林。森林斑块的数量在森林草原交错带的森林草甸区最多,其次是森林带,再次是森林草原交错带的草甸草原区,草原带没有森林斑块。从森林带到森林草原交错带,森林斑块变小、森林景观破碎化程度提高。森林草原交错带森林景观的形成是气候变化和现代气候、地形、火灾和人为活动综合作用的结果.

Abstract: There are forest landscapes such as Betula platyphylla,Populus davidiana,Picea mongolica,Quercus mongolica and Ulmus pumila within the forest-steppe ecotone in northern Hebei Province and eastern Inner Mongolia in China.The number of forest patches in forest-meadow region is more than that in forest zone and in meadow -steppe region.From forest zone to the ecotone,forest patch size decreases while forest fragmentation increases.Forest landscapes of forest-steppe ecotone are resulted from global climatic change,landforms,fire and human activities.
