| 摘 要： | 基于遥感(RS)和地理信息系统(GIS)技术,以2010年中巴资源卫星所接收的CCD/HR影像为数据源,结合影像数据和现场实景资料,综合分析了五台山地区的植被景观的格局。结果表明:在植被景观斑块类型中,斑块面积最大的是山地草甸,最小的是云杉和臭冷杉林。斑块数最多的是温带草原及灌草丛景观,最少的是云杉和臭冷杉林景观。各景观要素斑块的分离度指数的大小顺序为:Ⅲ>Ⅹ>Ⅱ>Ⅰ>Ⅵ>Ⅳ>Ⅴ>Ⅶ>Ⅸ>Ⅷ,这个顺序与该地区的斑块密度的排序基本吻合。此外,分离度指数与斑块密度呈正相关关系即分离度指数随着斑块密度的增大而增大。

| Abstract: | Remote sensing(RS) and geographic information systems(GIS) technology are important tools for ecological landscape pattern research,especially in the study of distribution characteristics,evolution law,spatial relationship of landscape phenomenon,and the simulation of ecological landscape pattern.The Landsat CDD/HR data in 2010,which covering the whole Wutai Mountain were used to analyze the vegetation landscape pattern.The results showed that maximum square measure of the patch density was mountain meadow and the minimum square measure of that was Picea,Abies nephrolepis.And the most quantity of the patch density was temperate grassland and shrub-herbage,while the least quantity of that was Picea,Abies nephrolepis.The landscape separation index was ordered as Ⅲ>Ⅹ>Ⅱ>Ⅰ>Ⅵ>Ⅳ>Ⅴ>Ⅶ>Ⅸ>Ⅷ.And the separation index tended to increase with growth of the patch density. |
