摘　　要：Sandy forest-steppe ecotone in Baiyinaobao Natural Reserve of Inner Mongolia Autonomous Region of China is one of the special landscape types in forest-steppe vegetation zone in China. Vegetation landscape types, landscape patches, and patch size were measured by the field investigation, forest photograph, and airscape. The structure of landscape patches in sandy forest-steppe ecotone, including composition structure, and size structure, was studied and the dynamics and transformation of landscape patches were analyzed. The data obtained in this study could provide theoretical basis for the research on vegetation landscape in forest-steppe ecotones and other vegetation types.位于内蒙古白音敖包自然保护区的沙地森林草原过渡带是我国森林草原植被带中非常特殊的景观类型之一。本文我们在系统研究中国沙地森林生态系统的基础上,研究了沙地森林草原过渡带的景观斑块结构,包括组成结构和大小结构;同时研究了景观斑块的动态及相互转化的规律。结果可为进一步研究森林草原过渡带及其它植被类型提供科学依据。表4参10。
