摘要： 以科尔沁典型沙区土地类型专题图形库为基础,对科尔沁地区30多年来沙地的动态演变进行了定量分析,认为该区由于人类活动因素的影响,50～70年代是沙漠化迅速发展时期;70～90年代是沙漠化发展加剧阶段;若减弱人类干扰或在人类帮助下,生态仍具可恢复性。

Abstract: A quantitative research on Horqin sandy area dynamic evolution has been done for more than thirty years, based on the thematic cartographic data base system of Horqin typic sandy area which has been established by themselves. Influenced by human activities the desertification developed very fast from the 1950’s to the 1970’s, and faster than before the 1970’s to the 1990’s. If reducing human interference or with the help of the people, the eco environment would be recovered again. And the research result will have an important effect on the general improvement and the eco environment recovery of Horqin sandy area.
