【摘要】 河岸林过渡带是河岸带的重要组成部分,在保护河岸带生态系统的结构、功能及其生物多样性方面有着重要的作用.河岸林林分过渡带宽度的划分是研究和保护河岸林及其群落的基础,也是河岸带生态系统管理和保护的必要工作.为了探究河岸林林分过渡带宽度划分的方法,采用重要值法对吕梁山西部山区山西省临沧市隰县下李林场的河岸林宽度进行判定.研究结果表明:不同林型的河岸林的过渡带宽度不同;河岸落叶松林过渡带宽度为40 m,河岸油松林过渡带宽度为20 m.更多还原

【Abstract】 Riparian forest transition zone is an important part of riparian zone,and it plays a very significant role in the protection of riparian ecosystem’s structure,function and biodiversity.Division of width of riparian forest’s transition zone is a basis for the study and protection of riparian forest and its community,and it is also necessary work for riparian ecosystem’s management and conservation.To explore a method for riparian forest transition zone’s division,this article uses important value means to determine width of riparian forest at Xiali forest farm in Lvliang Mountain area.The result of the study shows that different forest type has different transition zone’s width;coniferous forest transition zone of river bank is 40 meters in width and Chinese pine forest transition zone is 20 meters in width.更多还原
