摘　　要：通过分析国内农田防护林更新研究进展,结合宁夏引黄灌区20世纪末建设的"窄林带、小网格"型农田防护林日趋成熟和衰老的现状,为适应新形势下农业耕作与田间管理、防护林维护等机械化作业需要,在确保防护效益稳定的前提下,提出了大网格林带更新技术和主要参数,以及农田防护林可持续经营对策,为科学指导宁夏引黄灌区农田防护林更新提供参考和技术保障。Based on the research progress and existing problems of farmland shelterbehs at home and abroad, combined with farmland shelterbelt maturity and aging of ＂narrow belt, small grid＂ in Ningxia Yellow River irrigation area in the end of the last century, in order to adapt to the new situation of agricultural cultivation and field management, forest protection and other mechanized operations needs, the technique updating and the main parameters of large-scale forest belt were put forward in this paper on the basis of ensuring the protection stability. Countermeasures of sustainable management of farmland shelterbehs were put forward to provide the research basis and technical support for the scientific guidance of farmland shelterbelt regeneration in Ningxia Yellow River irrigation area.
