石林景区湖泊湖滨带土地利用景观格局研究

Research on Landscape Patterns of Land Use in Lakeside Zone of Lakes in Stone Forest

以2006年Quickbird遥感影像为基础数据,利用GIS技术对石林景区岩溶湖泊湖滨带土地利用类型进行遥感解译与制图,在此基础上运用景观类型指标(如斑块数量、斑块面积)和景观格局指标(如景观均匀度、景观优势度、景观破碎度、景观分维数)对研究区土地利用空间格局进行定量分析.结果表明:长湖林地面积占82.86%,受人为保护最好,具有良好的自然性;比目潭和绿芳塘受人为干扰较大,土地利用类型较多,土地格局凌乱.

Based on Quickbird remote sensing image of 2006, the article utilized GIS technique to interpret an draw a remote sensing map of the lakeside zone of karst lake in Stone forest. Landscape type index （such as number of patches,area of patches） and landscape pattern index （such as evenness,dominance,fragmentation,fractal dimension） were used to quantitatively analyse landscape spatial patterns of land use in the study area. The results show forest land area accounts for 82.86% in Long Lake, which to be the best protection of human and have better naturalness. Bimu lake and Lvfang lake which were largely influenced by humanity,were of more land use types and of messier land use patterns.
