Analysis of Iand Types Using High-resolution Satellite Images and Fractal Approach

摘要

The purpose of this work is to study the land cover and land types of Nanji Island. A scene IKONOS image was taken to classify the land types including village, farmland, shrubbery, meadow, reservoir, sands and so on. Then several models were built base on fractal theory to analyze the land types. Condition of the land cover and land use was analyzed at three aspects as following: 1) effects of patch area; 2) fractal characters of land types; 3) test of difference of fractal character between every two land types. The results show that the values of D of meadow and shrubbery are higher, and those of farmland and village are smaller, and that the fractal characters are determined by the degree of interferes of human activities.
