摘要
对大小兴安岭森林植被交错区的地理位置、地形地貌、气候、土壤类型、植被类型以及生态脆弱性等进行了论述。在交错区内 ,随着气候从温带向寒温带逐渐过渡 ,土壤、植被等表现出明显的梯度变化 ,该地区又是我国近百年来温度增加最明显的区域 ,导致冻土等环境条件的显著变化 ,为研究气候变暖对森林生态系统结构、功能的影响提供了良好的场所 。
The location, topography, climate, soil, vegetation and ecological fragility of the forest ecotone in Daxing'an and Xiaoxing'an mountains are described. In this ecotone, climate, soil and vegetation have obvious gradient, and have the most temperature increase in recent hundred years in China, which leads to environmental changes such as permafrost. Therefore the ecotone is of great importance in global change study due to its special location.
