【摘要】 荒漠化是全球性的环境问题，是当前国内外的研究热点之一。本文在深入剖析荒漠化相关概念的同时，以阜新地区为例，提出了土地利用类型+荒漠化类型+荒漠化程度的三级分类分级指标体系，并以此为基础，采用RS与GIS技术相结合的方法，利用三个不同时相的遥感影像，对该区21年来的土地荒漠化进行了动态监测，并在此基础上，完成了对荒漠化演化规律的研究。更多还原

【Abstract】 As a global environment problem, desertification is becoming one of the research hotshots around the world. In this paper, Fuxin area is chosen as an example. After analyzing the concepts of desertification, an index system on classification and assessment of desertification is put forward, which uses the types of land use, the types of desertification and the desertification degrees. Based on this index system, a dynamic monitor of desertification that covers 21 years in this area is made, using remote sensing images from three different time phrases, RS and GIS techniques. When this has been done, the evolution patterns of the desertification are researched.更多还原
