| 摘 要： | 依据1989年和2004年两个时相的TM、ETM^＋卫星遥感图像和其他辅助资料，提取龙口市耕地信息，并在此基础上分析耕地的空间格局转变。同时对龙口市耕地的平均斑块形状指数、斑块的分维数、景观破碎度指数进行计算分析，发现区域内耕地斑块数增加，整体的破碎程度增大，景观形状变得较为复杂。分析结果为有效治理整体景观并使其朝良性方向发展、恢复提供了科学依据。

| Abstract: | We acquire the plantations information of Longkou city from the 1989 and 2004 TM an ETM^＋ satellite remote sensing images and other auxiliary information, to analyze landscape pattern dynamics of the plantations and to compute and analyze average patch shape index, patch dimensions and landscape fragmentation index. Analysis results demonstrate that the number of patches and the extent of landscape fragmentation increase, that the shape of Landscape Pattern become more complex, and that the interference of human activities and natural factors reduces the areas of amble land and make landscape Pattern more complicated. This results provide the scientific foundtions for landscape pattern development and recovery. |
