摘要
在内蒙古多伦县土地沙化现状的调查中 ,利用多波段卫星图象 ( TM)数据 ,根据多伦地区各类地物的波谱特征 ,采用了假彩色合成及比值假彩色合成等遥感图象处理方法 ,在地理信息系统技术的支持下 ,对多伦地区沙化土地的空间分布和面积进行了详细的解译和测算。同时结合常规调查方法 ,对区内沙化土地的沙化程度、成因机理、发展趋势及危害等方面做了详细的研究和分析。作者向多伦县地方政府提供了真实可靠的各类土地利用现状的数据和其他信息 。
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.
