阿巴嘎旗在沙源治理建设中，本着“先急后缓、先易后难、相对集中连片、综合治理”的原则，采用封飞造模式，动员社会各界力量齐抓并进。在项目的操作上，主要采取分片承包的方式，明确责、权、利，克服劳动力少、科技含量低的不足，使建设质量、规模、速度有了明显提高。 ２０ In the construction of sand source governance, Abaga Banner adopts the principle of “first aid and postponement, first easy and hard, relatively concentrated and contiguous, comprehensive management” and adopts the mode of “sealing fly” to mobilize all sectors of society. In the operation of the project, we mainly adopted the method of fragmentation and contracting to clarify the responsibilities, rights and benefits, overcome the shortage of labor force and low scientific and technological content, and significantly improve the quality, scale and speed of construction. 20
