| Abstract: | Based on the reflection spectral characteristic of the land surface feature in Duolun area, by using multispectral satellite image data and adopting image processing of false color composite and ratio false color composite, with support of Geographic Information System, the space disbribution of the land desertification is interpreted and measured in this paper. By combining with conventional survery methods, the degree, reason, development trend and danger of the land desertification in this area are discussed. The reliable data of the land use present situation and other information are provided for Duolun local government. This paper provides scientific basis for the rational utilization of land resources and prevention and control of the land desertification in Duolun. |
