摘要
利用1992年、2005年两期遥感影像,在RS、GIS技术的支持下,对两期遥感影像进行处理.在此基础上,运用生态学原理,在景观类型水平和景观水平上选取类型面积、斑块个数、平均斑块面积、最大斑块指数、斑块分维数、香农多样性指数、香农均匀度指数、蔓延度指数等景观指数对研究区进行定量分析,结果表明:旱地仍然控制着蓬莱市的景观;景观优势度在减少,旱地占支配地位的程度有所下降;景观在人为作用下,破碎度在增加.
Using RS and GIS technology, two periods of remote sensing images in 1992 and 2005 have been delt with. On this basis, catalogion area, number of patches, the largest patch index, fractal dimension index, shannon＇s diversity index,shannon＇s eveness index and other indexes were selected and analyzed. The results show that： dryland still dominates the local landscape; the predominance of landscape is decreasing, the superiority of dryland has dropped; with the effect of human, the fragmentation of landscape is increasing.
