旱作农业生产力分析方法与预测模型

The Analytical Method of Productivity of Water Resources in Rain-fed Agricultural Regions and Its Prediction Model

通过对雨养农业区天然降水与粮食作物单位面积产量水平的分析,提出了旱作农业生产力分析与计算方法,建立了基于水分供给和时间变化的二元产量模型,为进行旱作农业区不同时段不同水平年条件下的作物产量预测提供了新的方法。

Based on analyzing precipitation and grain crop output per unit area in rain-fed agriculture regions, the ways of analyzing and calculating the productivity of water resources in rain-fed agriculture are proposed, and the two yield models based on water sup- ply and changed time are also built. This paper offers a new way to predict crop yield under different conditions in differentlevel years in rain-fed agricultural regions.
