- Title:
- Grey Forecast of Grain Plant Output in Lingbao County
- 摘要:
- 灵宝县具有“七山二原一份川”的立体地貌,在黄土高原地区具有一定的代表性.本文应用灰色预测的方法,利用本县各种粮食总产与单产的多年统计资料,对今后十年内各种粮食作物的总产与单产进行了预测.结果表明,要完成本县在粮食作物发展规划中所提出的任务,就目前这种生产水平是不易实现的.因此,为了达此目标,需要对作物布局做最优调整.
- Abstract:
- The stereoscopic landforms of Lingbao County is "7 mountain,2 plateau,1 plain".So that,it is a type in loess plateau hilly region.The way of grey forecast in this paper is used with many years statistical material of grain plant output and per unit area yield of the county,makes the forecast to grain plant output and per area yield of the county in the future 10 years.The result shows that it is impossible to reach the target that has been put forward in the grain plant development planning on the modern productivity level.In order to catch the target we must make the optimal adjustment to the crop arrangement.
