摘要： Although agriculture has traditionally been primarily the concern of the world, it now plays an increasingly important role in how we meet challenges international food security, environmental protection, climate change, energy supply, economic sustainability, and human health. With population growth and environmental deterioration, the attention about food security and sustainable agriculture is on the increase, and the status of ecological agriculture comes into prominence. Perennial grain crops would address many agricultural problems as well as substantial ecological and economic benefits, which can provide multiple ecosystem services essential for sustainable production more effectively than production systems based on annual crops, such as protecting against soil erosion, conserving water and nutrients, storing more carbon below ground, and building better pest tolerance. This paper presents some of advantages of perennial grain crops as a new option for the food security and ecoagriculture, as well as prospects the significant utilization of perennial crop on sustainability of agriculture and environment in the future.
