旱作物生育期有效降水量计算模式研究进展

Research Progress on Calculation Methods of Effective Rainfall in Growing Period on Dry Crop

在查阅国内外相关文献的基础上,对目前有效降水量的研究方法进行了简要的评述,并结合现有有效降水量计算模式,对它们的适应性和计算结果的可靠性进行了对比分析。结果表明,各种计算模式均存在一定的局限性,不同模式在同条件下模拟计算的结果存在明显的差异。最后,对该领域存在的问题及未来的研究方向作了简要的探讨。

Based on the pertinent iterature, the calculation methods of effective rainfall in growing period on dry crop was analysed and summarized in this paper, which combines with research situation of calculation methods of effective rainfall. The results from calculation examples show that all kinds of calculation methods have certain limitations and the result differences with calcaulation methods at the same condition were clear. Finally the existing problem and research direction in the future in this field also was briefly discussed in this paper.
