摘要
以3S空间分析术为基础,以挠力河流域为研究对象,解译了挠力河流域TM卫星影像,绘制了详细的挠力河流域的景观格局图,然后提取景观元素的多种参数,再经过Fragstats软件计算得到各类景观指数;分别研究了不同斑块类型的斑块面积、斑块密度、边缘密度、分形维数、景观多样性指数、斑块形状指数、景观丰富度指数、景观均匀度指数等指标,取得了挠力河流域景观信息的大量第一手资料,揭示和验证了挠力河流域景观空间格局的基本规律。
It is interpreted the TM satellite images of the Naoli River basin pointed the wetland as an objective of this study, which was based on the 3S space analysis technology. The detail landscape pattern map of the wetland in Naoli River basin was drawn in the Erdas Imageine and Arc GIS program platform. Then the indices of landscape information have been calculated from the landscape elements by the Fragstates program. The research region was divided into 8 kinds of patche classese. It have been analyzed for the indices such as patch area patch density, perimeter density, fractal dimension, landscape diversity index, patch shape index, landscape richness index, and landscape evenness index etc. The abundant preliminary landscape data has been obtained, and the general rule of landscape space pattern has been revealed and validated of Naoli River basin
