沙被规模分类及其规模与生态效应

Classification of Sand Cover based on the Scale and the relationship with its ecological effect

通过对沙被规模分类的研究,可以促进对沙被规模大小差异较为系统的认识,使相关研究和表述更为细化,并促进对中、小规模沙被的研究、认识与保护、利用。文章提出了度量沙被规模的各项指标,并以沙被面积大小作为沙被规模分类的指标将沙被划分为小规模、中规模、大规模、特大规模和超大规模5个等级。同时,对沙被规模、形状与其生态效应之间的关系进行了探讨。

Through the study of sand cover scale classification, it can promote the systematic understanding of sand cover scale difference, make the related research and expression more detailed, and promote the research, understanding, protection and utilization of smaller sand cover. This paper proposes a factor to measure the scale of sand cover and determine the size of sand cover area as the index of sand cover scale classification. According to the area of sand cover, the sand cover is divided into five grades: small scale, medium scale, large scale, especial large scale and super large scale. At the same time, the relationship between the scale and shape of sand cover and its ecological effect is discussed.
