| 摘 要： | 利用宁夏中卫市1979～2008年的降水量资料,通过降水量距平百分率法对该地区的农业干旱程度及特点进行了研究,并对当地主要农作物(春小麦和玉米)关键需水期的干旱程度进行了评估。结果显示:宁夏中卫市农业干旱具有季节性、持续性、随机性和频繁性的特点,其中以春旱和春夏连旱发生的频率较高。据此,作者提出了相应的抗旱技术措施。

| Abstract: | The paper studied the degree and characteristics of agricultural drought through the precipitation anomaly percentage method by using the precipitation data from 1979 to 2008 in Zhongwei city,Ningxia,and assessed the drought degree of the local staple crops(spring wheat and maize) in their critical period of water demand.The results showed that the agricultural drought in Zhongwei city had seasonal,constant,random and frequent characteristics,and the occurrence frequency of spring drought and spring-summer ... |
