| 摘 要： | 根据农田水平衡原理,逐年模拟了农业干旱的发生、发展和缓解的全过程,对所得到的多项表征干旱过程的指标进行了统计分析.参考不同生长期作物缺水对产量影响的试验资料,定量模拟了作物因旱减产的程度,确定了干旱等级.经初步检验,拟合效果较好.

| Abstract: | On the basis of farmland water balance principle, this paper presents a simulation approach to simulate whole process of occurrence. expanding and mitigation of drought events. Simulated results and indices characterized drought event process are analyzed statistically. According to the experimental data about the effect of water shortage in different crop growth periods on crop production sensitivity, the drop of crop production is evaluated quantitatively and the degree of drought event is determined reasonably. It is valid that the simulation results basically fit with the actual cases. |
