摘要
Agroforestry characterizations were conducted in rustic and traditional coffee plantations in San Miguel, Amatlan de los Reyes, Veracruz, Mexico. The aim of the present study was to analyze and compare these systems. Results indicate that both systems gained similar economic benefits, although the species composition of the canopy and products obtained are different. Timber (Cedrela odorata, Robinsonella mirandae and Mastichodendron capirii), coffee (Coffea arabica and C. canephora) and palms (Chamaedorae tepejilote and Chamaedorae elegans) are the main economic products. The benefit/cost ratio acquired by selling agricultural and forest products shows a greater economic profit for rustic coffee system ($ 20,784.00.year(-1).ha(-1)) compared to traditional coffee system ($ 19,236.00.year(-1).ha(-1)). Although both systems have relatively good gains, the effect that the rustic coffee system has on forest resources may be shortly sustainable over time, because reforestation does not occur in this case. Traditional coffee system is in a better condition of sustainability and long-term production, because the elements used in the marketing of timber and fuel are reforested due to their commercial importance.
