Excessive agricultural investment brought about by increased multiple-cropping index may compromise environmental sustainability. There are few studies on the sustainability of diversified multi-cropping systems in Yangtze River Basin (YRB). Therefore, this study selected five representative locations YRB. According to local climate characteristics and food demand, were designed, main winter crops as previous corn-soybean strip compound cropping system, with traditional double-cropping model control (CK). The emergy evaluation method was introduced quantitatively compare efficiency results showed that incorporating soybean intercropping corn, compared CK, total energy input, annual output, economic output 15.80%, 9.78%, 33.12% average, respectively. unit value (UEV) non-renewable (UNV) 6.03% 5.98%, respectively; yield ratio (EYR) loading (ELR) decreased 0.91% 0.44%, (ESI) same.

The eco-agricultural park is a new comprehensive agricultural technology system integrating production, rural economic development, ecological environment protection, and efficient resource utilization. Therefore, an in-depth analysis of the ecosystem structure parks will help achieve goal coordinated symbiosis between human development environmental protection. This study takes research area Eco-agricultural Park Jinchuan Town, Huinan County, typical town in Changbai Mountains Northeast China. Based on field surveys, market research, farmer consultation, related data collection, emergy theory methods are used to construct model for park. value evaluation index integrates unique with traditional conduct targeted park’s functional sustainable capabilities order improve efficiency material energy use provide technical reference construction industry mountainous areas northern results show that: (1) annual input total 4.04E+24 sej/a, labor input, electricity topsoil loss relatively high. labor-intensive stage. output 5.09E+24 dominated by planting forestry industries. (2) utilization intensity high—production high, advanced, system’s self-control, adjustment, feedback functions vital—and plays significant role promoting regional economy. However, relies more investment from external resources, production puts pressure environment. (3) current capability weak, factors affecting mainly uneven distribution industrial Effective measures promote transformation develop technology-intensive industries performance were proposed. These include: adjusting proportion park; reducing high-energy emergy, such as auxiliary emergy; non-renewable natural resources through engineering measures, depth slope runoff combining modern resource-based environmentally sound management reduce rational resources.

The construction of an appropriate cropping pattern is crucial for the improvement regional agricultural economic efficiency and sustainable development. Despite previous efforts, there remains a gap in optimizing patterns that fully leverage climate resources to enhance production efficiency. This study addresses this by systematically comparing differences resource allocation, crop response among models constructing four new triple-maturing at typical ecological sites hilly areas southwest China. To solve above problems, we constructed eight classified them three as follows: Traditional Double Cropping System, Triple Novel System. results showed multi-maturing planting was significantly better than traditional two-maturing netting three-maturing terms light, temperature water productivity. Compared with two-maturity net model three-maturity model, increased light energy productivity 97.88% 50.00%, respectively; use average 0.48% 0.31%; cumulative 84.70% 49.14%; rainfall 101.04% 49.61%. An assessment meteorological different treatments on 111.58% 74.78% higher pattern, T6 having highest multi-ripening has demonstrated stability changes resources, adapting weekly changes, stabilizing yields improving In summary, can provide theoretical basis promoting agriculture Future research should focus further refining these models, exploring their adaptability various climatic conditions, evaluating long-term environmental impacts.
