摘要:

基于甘肃省59站的1961-2008年月平均气温和月降水量资料,计算了陆面蒸散量、干燥度及线性变化率,揭示了甘肃省气候暖干化的事实,分析了暖干化及与农业干旱灾害的联系。结果指出:甘肃近48 a气温呈上升趋势,降水量呈减少趋势,干燥度呈增大趋势,气候暖干化趋势明显;气候暖干化导致了干旱灾害频繁发生,是农业受旱灾面积扩大,粮食减产的主要原因。

Abstract:

Based on the data of monthly average temperature and precipitation from 59 meteorological stations in Gansu Province, the dryness indexes were calculated, and the impacts of climate warming and drying on the agricultural drought disaster were investigated. The results show temperature increased, precipitation decreased, dryness index increased in the past 48 years in Gansu Province, which resulted in drought events occurring frequently, agricultural drought disaster areas extending in this region.
