Agroforestry systems can play an important role in mitigating the effects of climate change given their capacity to increase tree diversity and to store more carbon than conventional farming. This study aims at assessing carbon stocks and the use of shade trees in different coffee growing systems in the Northeast Peruvian Amazon. Carbon stocks in trees were estimated by field-based measurements and allometric equations. Carbon stocks in dead wood, litter and soil (upper 60 cm) were determined using field sampling and laboratory analysis. The diversity analysis drew on the Shannon–Weiner diversity index, and focus groups were used to obtain information about the local use of shade trees. The total carbon stock in the polyculture-shaded coffee system was 189 t C/ha, while the Inga-shaded and unshaded systems totalled 146 and 113 t C/ha, respectively. The soil compartment contributed the largest carbon stock in the coffee growing systems and contained 67, 82 and 96% of the total carbon stock in the polyculture-shaded, Inga-shaded and unshaded coffee systems, respectively. The Shannon–Weiner index and tree species richness values were highest for the polyculture-shaded coffee system, with a total of 18 tree species identified as important sources of fodder, food, wood, firewood and medicine. Therefore, coffee agroforestry systems play a significant role in carbon storage, while promoting conservation of useful trees in agricultural landscapes in the Peruvian Amazon.

农林业系统在增加树木多样性和比传统农业种植更多碳的能力方面，在减轻气候变化的影响方面可以发挥重要作用。这项研究旨在评估秘鲁东北亚马逊东北部不同咖啡种植系统中的碳储量和遮荫树的使用。通过实地测量和异速方程估算树木的碳储量。使用野外采样和实验室分析确定了枯木，垫料和土壤（60厘米以上）中的碳储量。多样性分析基于Shannon-Weiner多样性指数，焦点小组用于获得有关遮荫树本地使用情况的信息。混养咖啡系统中的总碳储量为189 t C / ha，而印加遮光和未遮光系统的总产量分别为146和113 t C / ha。在咖啡种植系统中，土壤隔室贡献了最大的碳储量，分别在混合培养阴影，Inga阴影和非阴影咖啡系统中分别占总碳储量的67％，82％和96％。混养阴影咖啡系统的Shannon-Weiner指数和树木物种丰富度值最高，共有18种树种被确定为饲料，食物，木材，薪柴和药物的重要来源。因此，咖啡农林业系统在碳储存中起着重要作用，同时促进了秘鲁亚马逊河农业景观中有用树木的保护。
