摘　　要：本文讨论了近年来我国西北、东北地区扩大林草面积的成功模式与导入草地生态农业体系的发展趋势。所运用的生态学依据有:运用生态控制论,促进生态系统耦合;运用生态工程原理,提高生产效率;运用生态技术,达到节水、节能目标。将社会调控机制与生态系统自身演化机能作良性耦合,以生态知识资源抢救草地生态资产与草地农业体系的前景广阔。This paper discusses successful modes of forest-grassland enlargement in northwestern and northeastern regions of China in recent years and its application trend in grassland agro-ecological systems in the country. Theoretical basis for the application include eco-kybernetics which accelerates eco-system coupling and synthesis; eco-engineering which enhances production efficiency; and eco-technology which saves water and energy. Synthesis of regulation and control mechanisms of society as well as developmental functions of eco-systems and the utilization of ecological knowledge to promote natural resources protection are very crucial elements of grassland agro-ecological systems.
