平潭综合实验区海坛岛土地利用变化及景观格局研究

Changes of Land Use and Landscape Pattern of Haitan Island within Pingtan Integrated Experimental Area

在RS和GIS技术支持下,以2007年的Landsat TM遥感影像图和平潭综合实验区总体规划主岛发展指引图为基础数据,对未来平潭综合实验区主岛海坛岛的土地利用与景观格局变化进行了分析.结果表明:在规划实施后,人类活动对景观的干扰强度越来越大,将导致建设用地面积大量增加,区域景观类型趋向单一,平均斑块面积增大,斑块数量减少,景观多样性与均匀度降低.景观格局变化的主要驱动力因素是政府政策的影响和人口变化等.

With the support of RS and GIS, and on the basis of remote sensing images in 2007 and according to the overall plan of Pingtan Integrated Experimental Area, this study analyzed the changes of land use and landscape pattern on Haitan Island, which is a main part of the experimental area. Results demonstrated that, if the plan is implemented, human activities would have a deep disturb- ance on island landscape. Especially, construction land use will be obviously increasing, landscape types tend to be more simplified, the average size of patches will increase while the number of patches goes down, and landscape diversity index and evenness index will both see a decrease. The driving forces of the land use and landscape changes are government policies and oooulation change.
