从鹿马岔农业发展模式看黄土高原半干旱区持续农业体系

An Agricultural Development Model in Lumapan and the Dryland Sustainable Agricultural System on the Loess Plateau

根据对鹿马岔小流域１０年综合研究与开发实践，提出“以肥调水—提高单产—退耕种草—稳定生态—养畜增收—全面发展”的旱地持续农业模式，认为黄土高原半干旱区持续农业发展要以耕地为主体，粮食为先导，农牧林综合发展；粮食生产是旱农持续发展的重点和难点，农村生态环境建设与农村经济建设必须双管齐下，旱地农业＋补灌提高水分利用率与利用效率是旱农持续发展的长期任务，造就新一代“知识型”

A special agricultural development model is proposed in this paper based on the ten years' research in Lumapan Small Catchment. It is indicated that the cultivated land, the grain production andthe integrated development of agriculture, animal hunsbandry and forestry are the three main factors for the sustainable agricultural development in the arid and semi arid areas on the Loess Plateau.
