摘要
计算出黄土高原水土流失区各类粮食生产潜力 ,采用Helmunlieth估算式计算了全区粮食气候生产潜力。提出了粮食持续增产的战略对策 ,为正确指导粮食的区域平衡政策提供可靠的科学依据。
In this paper, be systematic analysis of grain yield from 1949 to 1995 in the loess plateau, and compared with present situation of grain production in our county and nearby region of loess plateau, we have some new ideas of fluctuation of grain production and divide up development period of the grain production and calculate the climatic production potentialities of grain in this area by using the Helmun equation The strategic countermeasure of sustained development of grain yield are put forward, these results give reliable base for policy of regional equilibrium to guide grain production
