摘要:

干旱是甘肃黄上高原雨养农业区最主要的气象灾害,干旱的发生包含许多复杂过程和条件,因而研究一个考虑因子较为全面的干旱指标较为困难。木文在美国帕尔默旱度模式和中国修正的帕尔默旱度模式的基础上,根据本区特点,从建模资料站点、可能蒸散计算、土壤田间持水量和径
流计算等几个方面进行了修正,并利用甘肃黄上高原12个站点的资料,建立了适用于本区的旱度模式,以期为木区的干旱研究提供一种有效的工具。

关键词: 甘肃黄上高原, 帕尔默旱度模式, 修汀

Abstract:

Dronght is the most serious meteorological disaster in GanSll  1neSS  pltateall.  It considering meteorological factors comprehensivly because of the complexity Model of America and the  modified Pahner  Drought Severity  Model for of drought .On is difficult to develop a drought index the base of  the Palmer Drought Severity China,  we fLn-ther  modified the model in  stations CalClllatlOn Of pOtentlal eVapOtTanSplTatlOn and TLInOff,  etC.  AS a TPSlllt ,a TPV1Sed m0(lel Of dTOllght SPVPTlty haS been eStahhShed In paper which is expected to he applicable for drought research on this region.
