摘　　要：依据1994年《国际防治荒漠化公约》的荒漠化定义,对内蒙古自治区东部的荒漠化现状进行了调查与划分,对荒漠化的分布特征及危害类型进行了论述.内蒙古自治区东部存在沙质荒漠化、土壤盐渍化及水蚀荒漠化3种类型.现有荒漠化土地面积148521.65km2,占调查区总面积的54.76%.荒漠化的发展,造成内蒙古东部草原退化、诱发沙尘暴、地下水位下降等环境地质问题.According to the definition by the International Convention of Desertification Control in 1994, the present situation of the desertification in Eastern Inner Mongolia is investigated and classified. The distribution and types of harmfulness of the desertification are discussed. It is concluded that three types of desertification occur in the region, i.e. sandy desertification, soil salinization and wet blasted desertification. The desertification covers an area of 148 521 km^2, accounting for 54.76% of the total studied area. The increasing desertification has caused a series of environmental problems such as grassland deterioration, sand storm, groundwater level lowering, etc.
