摘　　要：浑善达克沙地是内蒙古自治区四大沙地之一 ,2 0世纪 6 0年代以后 ,该沙地发生了严重的沙漠化 ,不仅恶化了当地的生态环境 ,制约了区域经济的发展 ,而且成为京津地区最主要的沙尘源之一 ,对京津、华北等周边地区人民的生产、生活和生态安全构成了愈来愈严重的威胁 .该文着重以浑善达克沙地腹地的内蒙古正蓝旗为例 ,从自然因素和人为因素两个方面对沙漠化成因和过程进行分析 ,确定该区沙漠化发生发展变化的主要驱动力 .并结合当地实际提出沙漠化防治的基本对策和措施 。Hunshandake Sandland, one of the four sandlands in Inner Mongolia, has seriously desertizied since the 1960's, not only deteriorating local eco-environment and restricting the development of territorial economy, but also becoming one of the main sand and dust sources in Beijing and Tianjin Region. Finally, it threatened the social, economic sustainable development and ecological security around Beijing, Tianjin and North China. Taking an example of Zhenglan Banner,Inner Mongolia, which is located in hinterland of Hunshandake Sandland, the causes and process of desertification was analyzed from natural and human factors. The main impetus of desertification occurrence, development and changes were confirmed, the counter measures were put forward to combat desertification. Some necessary theories and decision-making foundation for the combating and management departments were provided.
