As agriculture's impact on the Earth has been amplified by industrial farming, the functioning of ecosystems around the world is disruptive. The phenomena of agroecological environment are becoming worse and worse in the arid and semi-arid regions, which has become the predominant obstacle for agriculture development. Through understanding the character of perennial crops and developing them, however, would help us to deal with the multiple issues in agroecosystems, such as agroecological environmental conservation, economic benefits and so on. It also can provide multiple ecosystem services including a new solution to the long-standing problems of soil erosion and degradation associated with conventional annual small-grain cropping systems. This paper assesses the derivation of agroecology and agroecosystems, introduces the agroecological value of perennial crop, and prospects the significant utilization of perennial crop in the future.
