摘要:
[目的] 总结黄土高原退耕还林(草)工程实施20 a来取得的成效,旨在为新时期黄河流域生态保护和高质量发展提供参考。[方法] 根据多年研究结果,结合近期调研和相关资料,归纳了新时期黄土高原退耕还林(草)工程实施过程中出现的问题。[结果] 当前需要考虑的问题包括: ①如何加速退耕还草;②是否实行严格的轮封轮牧;③如何处理好生态林和经济林的比例;④如何持续提高单位面积粮食产量等。[结论] 新时期生态建设过程中需注重分析与研究出现的新问题,寻求切实的应对方案,以推动黄土高原地区生态文明建设和乡村振兴。

Abstract:
[Objective] The achievements after the implementation of grain for green (GFG) project on the Loess Plateau for 20 years were summarized to provid references for ecological protection and high quality development in the Yellow River basin in new era.[Methods] Based on years of research results, combined with recent surveys and some documents, some new issues during GFG project implement were analyzed.[Results] The issues which should be considered at present include:how to accelerate the grassland construction; whether to carry on strict rotational grazing; how to deal with the ecological and economic forest proportion; how to continually improve the grain yield per unit area.[Conclusion] It is necessary in the new era, to lay emphasis on the study and analysis of the emerging issues during ecological construction, and seek practical solutions, so as to promote ecological civilization construction and rural revitalization in the Loess Plateau region.
