摘　　要：根据陕北农牧交错带的生态环境特点以及牧草生长发育过程对水热资源的要求和利用效率,运用迈阿密模型定量估算陕北农牧交错带七县区牧草自然生产力。并与牧草现实生产力进行比较。研究表明:陕北农牧交错带牧草现实生产力仅为自然生产力的30.80%。基本掌握了该区牧草生产力状况和特点,并据此提出了相应的开发战略和实施途径。Based on environmental characteristics and the requirement and use efficiency of heat and water resources by grass in their developing process,this paper estimates the potential grassland productivity in quantities by using Miami Model of seven counties in agriculture and pasturage interlaced zone of northern shaanxi. We compare it with grassland actual productivity. It is surveyed that in this region the grassland actual productivity is 30.80% of the potential grassland productivity. At the same time, this paper grasps the status and character of grassland productivity basically, hereby describes the exploitive stratagem and guiding suggestions of improving the grassland productivity.

关 键 词：陕北农牧交错带 牧草自然生产力 牧草现实生产力
