摘要
针对定西安家沟流域的自然特点,提炼出了3种典型的农林复合模式,即:林-粮复合经营模式、林-草-畜复合经营模式和庭院经济复合经营模式。分别分析了3种模式的组成、结构及功能,对3种模式的经济效益进行了评价。结果表明:与坡地农田系统相比,3种典型的农林复合模式均具有较高的经济效益。其中庭院经济复合经营模式效益最大,林-草-畜复合经营模式效益次之,林-粮复合经营模式效益最低,但均高于对照模式,在实际生产中,应结合具体情况,营建相应的模式,以追求最大的经济效益与生态效益。同时对各种农林复合模式的经营技术进行集成和优化,并提出了科学、高效地开展栽培、经营、管理及利用技术。
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.
