摘要

以咖啡为基础的农林复合系统(AFS)是提高热带地区抵御力和生产力的可持续替代方案。然而,有限的研究系统地评估了影响其成功的综合农艺和经济因素,特别是在秘鲁的安第斯森林地区。本研究旨在评估位于秘鲁西北部亚马逊州Rodríguez de Mendoza的AFS的树木组成、土壤参数、害虫发生率和经济效益。通过非概率目的抽样选择15个地块。利用重要值指数(IVI)分析树木组成,同时评价土壤肥力、害虫发生率和盈利能力。关键树种包括蓝桉(13.5% IVI)和雪松(11.3% IVI)等木材树种,以及因加(12.9% IVI),后者与改善土壤有机质含量(2.8 - 5.7%)和减少中等遮荫条件下害虫发生率(30 - 45%)的相关性更强。土壤pH值(5.2 ~ 6.7)和碳含量与树木多样性呈显著正相关。经济上,生产成本在1300 - 1400美元,收入在2400 - 3200美元;66.7%的地块的效益/成本比大于2。回归分析显示,遮荫覆盖率对盈利能力有显著的正向影响(p <;0.05),而运输和加工成本对结果产生负面影响。这些结果强化了以咖啡为基础的AFS作为小农可行战略的作用,将生态服务与经济可持续性相结合,并支持秘鲁目前为气候适应型农业政策所做的努力。

Agronomic and economic sustainability perspectives in coffee-based agroforestry system (Coffea arabica L.) in Rodríguez de Mendoza, Amazonas, Peru
Coffee-based agroforestry systems (AFS) represent a sustainable alternative for enhancing resilience and productivity in tropical regions. However, limited studies have systematically evaluated the combined agronomic and economic factors influencing their success, particularly in Andean forest regions of Peru. This study aimed to assess tree composition, soil parameters, pest incidence, and economic performance in AFS located in Rodríguez de Mendoza, Amazonas, in the northwest of Peru. Fifteen plots were selected through non-probabilistic purposive sampling. Tree composition was analyzed using the Importance Value Index (IVI), while soil fertility, pest incidence, and profitability were evaluated. Key species included timber species such as Eucalyptus globulus (13.5 % IVI) and Cedrela montana (11.3 % IVI), along with Inga edulis (12.9 % IVI), the latter being more strongly associated with improvements in soil organic matter content (2.8–5.7 %) and reduced pest incidence under moderate shade conditions (30–45 %). Soil pH (5.2–6.7) and carbon content showed positive correlations with tree diversity. Economically, production costs ranged from 1300 to 1400 USD, with incomes between 2400 and 3200 USD; 66.7 % of plots achieved benefit/cost ratios greater than 2. Regression analysis revealed that shade cover had a significant positive effect on profitability (p < 0.05), while transportation and processing costs negatively impacted outcomes. These results reinforce the role of coffee-based AFS as a viable strategy for smallholders, integrating ecological services with economic sustainability, and supporting current efforts toward climate-resilient agricultural policies in Peru.
