Abstract:
We systematically elaborated and compared the spatial scope and landscape changes of Horqin Grassland and Horqin Sand Land from their definitions and ranges. Horqin Grassland is an area with geographical units named after Mongolian tribes, but the boundary is unclear. Horqin Sand Land is also an area that borrows tribal names, but has independent topographic and geomorphic units, and clear boundaries. Horqin Grassland and Horqin Sand Land belong to two spatial regions that are both cross and different. The area and range of Horqin Grassland are larger than that of Horqin Sand Land which has obvious regional characteristics, and is a typical and research object area to study the development and restoration of aeolian desertification. Based on those cognition, we summarized the technologies and example models of comprehensive land management and desertification controlling over the years, and finally sorted out what should be focused on in the future to serve the annihilation war against desertification for Horqin Sand Land.
本文首先从定义、空间范围以及土地退化演变等方面对科尔沁草原与科尔沁沙地进行了较为系统的阐述和分析对比,科尔沁草原是一个以蒙古族部落名称命名兼具地理单元特征的区域,但边界不清晰;科尔沁沙地是借用部落名称但具有独立地形地貌单元的区域,边界明确。科尔沁草原与科尔沁沙地既有交叉又有不同的两个空间区域。科尔沁草原区域大、范围广,而科尔沁沙地范围小但区域特色明显,已成为研究土地沙漠化发展与恢复的典型区域。以此为基础, 回顾和总结了多年来科尔沁草原和科尔沁沙地相关的综合治理技术、模式以及取得的成效,整理归纳了今后沙地综合治理的焦点及亟待解决的问题,以期为当前科尔沁沙地歼灭战服务。.
