摘要
文章是以石林景区为例,利用TM影像、扫描地形图、野外样方地调查数据为基础,利用G IS、RS软件平台,对扫描地形图进行了基于公里格网的配准,对图像进行了投影变换和几何校正处理,并以建立掩膜层的方法提高了分类的精度。运用景观生态学原理和方法,选取分维数、斑块密度、景观多样性等指标,利用Fragstats3.3进行景观计算,对景区的景观格局进行了分析。
Based on the TM images, scanning topographic maps and field sampling survey data, the maps and projection transformation of images was registered with ArcGIS 9.2. The geometric correction of images were completed with ENVI4.2. Then the mask layers to enhance the accuracy of the classification was established. Using the fractal dimension, plaque density, landscape diversity, landscape calculation was done with Fragstats3.3. At last, the landscape pattern was analyzed using the principles and methods of landscape ecology.
