摘要
通过分析水分平衡过程诸分量建立了一个较为实用,并具有较好物理基础的干旱指数计算模式。应用分析和检验结果表明,这种干旱指数能较好地综合反映旱涝气候特征和干湿程度变化对农业生产的不同影响。
A more practicable computation method for drought index on a good physicalbasis is established by comparing and analysing the components of water balance. Re-sults suggest that the drought index obtained by this method can well reflect the climaticcharacteristics of drought and flood. and their influence on agriculture.
