摘　　要：作为林业生态工程的重要组成部分 ,农田防护林在控制风沙干旱、提高农业生产水平、建立新的生态平衡、发展区域经济等方面发挥着显著作用 .从实现高效、持续、稳定的总目标出发 ,农田防护林必须具有三个主要特征 :工程在空间布局的合理性、林分的多样性和稳定性、工程效益的连续与高效性 .要达到这个目标 ,必须对该生态系统进行合理经营管理 ,维持农田防护林最佳结构 ,以期达到最大的防护效益 .因此 ,农田防护林的经营管理对其防护作用的维持和整个农田生态系统健康的维系有重要意义 .该文从农田防护林生态系统结构调控、防护成熟、更新方式、高效持续经营的标准与指标体系以及可持续经营模型等几个方面 ,综述了农田防护林生态系统经营管理研究进展和存在的主要问题 ,阐述了今后在经营管理研究方面需要开展的主要研究工作 。As an important part of forestry eco-engineerings, farmland shelterbelt is significant to control desertification, improve farm production, establish new ecological balance, and develop regional economy. Farmland shelterbelt must bear three major characteristics, i.e., reasonable spatial distribution, diversity and stability, and sustainable effects of protection. Accordingly, the shelterbelt ecosystems should be managed reasonably. In this paper, the authors discuss the advances in management of farmland shelterbelt ecosystems and some problems existing in the research from the structure adjustment, protection maturity, regeneration models, indices and criteria of highly effective and sustainable management, and sustainable management models of shelterbelt ecosystems. Furthermore, some important researches to be developed in shelterbelt management in the future and the new demands of ecological and environmental construction for farmland shelterbelt eco-engineering are put forward.
