| 摘 要： | 科尔沁沙地是我国自然条件相对较好的一个沙地，有着广阔的治理前景。回顾科尔沁沙地的历史变化，认为科尔沁沙地是一个全球气候变化大趋势下由人类生产活动过度而形成的沙漠化区域，在金代至清代之间由于人为活动强度减弱，曾经发生明显的沙漠化逆转。根据全国沙漠化普查所获得的资料，研究分析了科尔沁沙地土地沙漠化现状及其特点，结合土地沙漠化发生的历史过程，讨论了这一地区沙漠化的治理策略。 |

| Abstract: | The Horqin Sandy Land has comparatively nice natural environment in sandy lands of China, this sandy land is hopeful for controlling desertification. Through retrospecting to the historical processes of desertification and some anthropological events in the study region, it is concluded that the Horqin Sandy Land was a desertified region resulted from irrational and overmuch human activities in the background of global climate change. This region ever experienced obvious reverse progress during Jin Dynasty to Qing Dynasty due to diminution of human activity. According to national desertification survey data, we have analyzed the present status of Horqin Sandy Land and its characteristics, and have discussed the strategies of controlling desertification in this region through combining with its historical desertification processes. |
