Optimizing Cropping patterns is important for the improvement of regional agricultural economic efficiency and sustainable development. However, there are few studies on sustainability cropping in hilly areas. Here, we studied four new three-maturing a typical ecological site areas southwest China. An analytical method combining evaluation energy value analysis was used to evaluate compare model traditional model. We explored construction three-crop suitable area improve benefits production production. To solve above problems, constructed eight classified them as follows: The Traditional Double System: T1, oilseed rape-summer soybean; T2, maize; T3, wheat-summer maize. Triple T4, wheat/spring maize/summer soybean. Novel T5, forage rape-spring T6, maize/peanut; T7, potato-spring T8, results study showed that compared with System System, increased yield by an average 100.39% 49.18%, capacity 71.32% 36.48%, biological 12.53% 4.90%, 13.59% 5.80%. were significantly improved, profits CNY 9068 ·hm−2 7533 System. further revealed characteristics high input output inputs 6.56% 4.25%, outputs 13.69% 4.27% respectively. This level stems mainly from significant increase labor inputs. Meanwhile, energy-value indicator shows its lower dependence natural resources, greater intensification, system stability. As result, higher capacity. In summary, this can provide theoretical basis optimizing promoting high-yield development agriculture.
