摘要
通过对纸坊沟流域植被特点的分析 ,阐述了森林草原交错带的边缘效应现象、形成机理和边缘效应的通道作用 ,并指出将交错带作为一个独立的分类单元不仅有助于解决黄土高原森林与草原的边界问题而且有助于对该区更进一步的深入研究。
According to the analysis of the vegetation characteristics of Zhifanggou watershed in Loess hilly region,this paper argued the phenomena and the mechanism of edge effect and the conduit of the ecotone,and suggest that it is helpful to resolve the argument of the borderline between the forest and the grassland to take the ecotone as an independent unit of a classification of vegetation.At last,the principal of the vegetative building in this region had been bought forward.
