- Abstract:
-
Based on the natural characteristics of Anjiagou watershed in Dingxi city, Gansu province, three kinds of typical agroforestry models were selected, namely that grass-crop composite farming model, forest-grass-livestock composite farming model and courtyard economy composite farming model. Meanwhile, the contrastive analysis was made on the composition, structure and function of three agroforestry models and their economic benefits were evaluated in the paper. The results indicated: there was higher economic benefit of three typical agroforestry farming models and their benefits were all higher than that of slope crop system. Among them, the economic benefit of courtyard economy farming model was the biggest, the second was the model of forest-grass-livestock composite farming and the benefit of forest-crop composite farming model was the lowest. In practical farming, the suitable model should be established in terms of local specific conditions so as to obtain maximum economic benefit and ecologic benefit. At the same time, the farming techniques of various agroforestry models have been integrated and optimized. And the scientific cultivation, management and utilization techniques were put forward too.
