摘要
根据１９５１～１９９５年各月总降水量、月平均温度等资料，在我国北方（３４°Ｎ以北）选取了３４个代表站，计算了春夏秋三季月总需水量和二种单站旱涝指标并作了比较，结果表明，Ｋ指标优于Ｚ指标；并对我国北方旱涝状况作了分析。
ased on the data of monthly precipitation amount and monthly mean temperature from 1951 to 1995,34 representative stations located in the north of 34°N in China are selected to calculate monthly water requirement,Z index and K index in spring,summer and fall respectively.The results show that K index is better than Z index.At the same time,the distribution of droughtflood in North China is analyzed.
