为了贯彻习近平总书记关于加强荒漠化综合防治、深入推进“三北”等重点生态工程建设重要讲话精神，打赢、打好河西走廊-塔克拉玛干沙漠边缘阻击战，开展阻击战核心区治理区划与分区治理任务研究。依据区域荒漠化土地和风沙活动特点，以“沙源不再危害，尘源有效控制”为目标，在对区域风、沙、尘源地，风沙输移规律、路径及其影响范围，自然地理特征，沙尘源地、风沙口、绿洲间防护缺口、绿洲外围流沙入侵地等空间分布进行系统梳理与分析基础上，提出区域荒漠化治理区划与分区治理的重点任务，以期为打好河西走廊-塔克拉玛干沙漠边缘阻击战提供科学支撑。

In order to implement the spirit of General Secretary Xi Jinping's speech on strengthening comprehensive prevention and control of desertification， further promote the construction of the "Three North" and other key ecological projects and win the battle against desertification in the core area of the Hexi Corridor-Taklimakan Desert edge （defined as “Battle Zone”）， the study of the management regionalization and the zoning management tasks in the core area of the Battle Zone were presented in this paper. According to the characteristics of sandy land and sand activities in the region， using "sand source is no longer causing damage and dust source is effectively controlled " as the goal， this paper systematically sorted out and analyzed the sources of wind， sand and dust， the law and path of sand transmission and its influence range， the natural geographical characteristics and the spatial distribution of the source of dust， wind and sand， protection gap between oasis， encroachment of sand outside oasis. Based on the above analyses， the management regionalization and the key zoning management tasks in the region were presented， so as to provide scientific support for the battle against desertification in the core area of the Hexi Corridor-Taklimakan Desert edge.
