Abstract: In order to deepen the understanding of protection and utilization of grassland in north China,develop systematic theory and technology of range and pasture management,and establish suitable forage production system and its utilization approach,we summarized principles and practices for range management,pasture production and utilization in North America.The research and management of rangeland and pastureland are within the scope of applied ecology.The principles and practice for rangeland need to consider specific units or regions,specific animal species and their grazing behaviors.Pastureland needs to select suitable forage crops or varieties according to specific units or regions and specific soils,while studies on yield process,nutrient dynamics,utilization approaches and sustainability of their natural growth and regeneration are required.Based on relevant criteria,we classified and regionalized a potential distribution pattern for range and pasture development in China,and suggested developing regional management principles and practices of range and pasture in China.
