毛乌素沙地治理与利用中存在的问题及解决对策

The Research on Comprehensive Treatment and Scientific Utilization of Mu Us Sandy Land

为了改善毛乌素沙地的区域生态环境和缓解土地供需矛盾,人们尝试了多种治理和利用毛乌素沙地的技术措施,但是这些治理和利用的技术措施存在着技术可行政策跟不上、缺乏实践、群众积极性差等问题。针对以上问题,逐一分析了各种治理技术措施存在的问题,并提出分区治理等解决对策,为毛乌素沙地的综合治理和合理利用提供了更切合实际的指导建议。

Mu Us sandy land is located in the depression of southeastern Ordos Plateau and the north of Loess Plateau of North Shaanxi, is an important part of the fanning-pastoral ecotone in North China. Human unreasonable reclamation and overgrazing causes the serious grassland degradation, desertification and frequent aeolian sand disaster. In order to improve the regional ecological environment and alleviate the contradiction of land supply and demand, people continuously try to use physical, chemical, biological, engineering and multidisciplinary cooperation in sand control technology to control and transform the desert. This paper introduces the basic situation of Mu Us sandy land and systematically summarizes a series of comprehensive treatment and utilization research, as of machine stabilization sands, sandy land improvement, chemical ＆ biological stabilization of sands, mixed into soil, ecological restoration, mechanical bulldozing and integrated control, on these bases, further discusses the countermeasures of land comprehensive treatment and rational utilization in Mu Us sandy land.
