摘要： Of human activities, agriculture is perhaps the most disruptive to the functioning of ecosystems around the world. As agriculture's impact on the Earth has been amplified by industrial farming, the agroecological environment is worsening. By developing perennial crops, however, would help deal with the multiple issues involving agroecological environmental conservation and economic benefits in a world of shrinking resources. It can provide multiple ecosystem services essential for sustainable production more effectively than production systems based on annual crops, such as reducing soil erosion, minimizing nutrient leaching, sequestering more C in soils, building better pest tolerance and providing continuous habitat for wildlife. This paper presents advantages of perennial crop system in agroecological benefits, introduces the important role of perennial crop at the development of sustainable agriculture, and prospects the significant utilization of perennial crop on conservation of agroecological environment.
