摘　　要：草牧场防护林是具有特殊作用、功能和意义的防护林林种。它不仅可以改善草牧场微域气候 ,增加牧草产量 ,改善牧草质量 ,提高草牧场生态经济系统的生产力和稳定性 ,而且可以增加生态系统的物种多样性和景观多样性 ,改善区域性生态环境 ,促进区域性自然—社会—经济复合生态系统的可持续发展。因此 ,2 0世纪以来对草牧场防护林的研究就已开始 ,特别是进入 2 0世纪 80年代之后 ,随着草原生态环境的急剧恶化 ,其研究日趋活跃。该文在参考了大量国内外文献的基础上 ,对草牧场防护林的概念、功能、作用、特别是营造技术等问题进行了系统的综述 ,并对草牧场防护林的营造技术进行了展望。在实施西部大开发的战略中 ,加强草牧场防护林建设 ,对于草原生态环境的恢复。Pastureland shelterbelt is a special kind of protective plantation. It does not only improve pastureland microclimate,increase forage grass yield and quality,raise the productivity of ecological and economical system of pastureland,but also can increase species and landscape diversity,improve compound ecological and economical system of regional nature-society-economy and promote its sustainable development. Therefore,the studies on pastureland shelterbelt have been begun since 1900's,especially ecological environment has become worse after 1980's, this research became more and more active. This paper systematically summarizes the concept, function and establishment technology about pastureland sheterbelts, put forward development tendency on the basis of consulting a large number of Chinese and foreign references.
