摘    要:以黑河流域下游额济纳荒漠绿洲为研究对象,分析了景观生态的基本特点和景观嵌块体类型,通过景观空间格局及其变化分析与景观生态功效的评价,利用80年代和90年代两期有关景观生态的资料,论述了水资源条件变化对研究区景观格局的影响,指出河流廓道是干旱区荒漠绿洲的主要生态流,河流廓道的变化是导致荒漠绿洲景观格局变化的驱动力。

关 键 词:干旱区  荒漠绿洲  水资源  景观空间格局  河流廓道

Abstract:Ejina oasis,located in the lower reach of Heihe River basin,was selected for the case study.The characteristics and types of the landscape were analyzed.By using the information of landscape ecology in 1980s and 1990s,the indices such as Dominance,Diversity,Homogeneity,Fragmentation and Separation were chosen to analyze the resources conditions.The landscape ecological functions were evaluated.The results show that,the river corridors are the most important ecological flow in the arid desert oasis and their changes are the drive power resulted in the variation of landscape patterns.
Keywords:arid area  desert  oases  landscape ecology  spatial pattern  water resources  influence
