摘要： 利用1961～2000年辽东地区13个观测台站的逐月降水和气温资料,分析了辽东地区降水和气温的年代际变化。并利用高桥公式计算出辽东地区的蒸发量,得出了该地区蒸发量和降水蒸发差的年代际变化特征;同时利用干燥度指标研究了辽东地区气候干旱对气候变暖的响应。结果表明:近40 a来辽东地区气候变化呈暖干变化趋势,即气温升高、降水减少,尤其以20世纪90年代变化最为明显。

Abstract: Based on the monthly air temperature and precipitation data of thirteen observation stations from 1961 to 2000 in eastern Liaoning province,the inter-decadal variabilities of air temperature and precipitation were analyzed in detail.Evaporation was calculated with Gaoqiao formula in eastern Liaoning province,and the inter-decadal variability characteristics on evaporation and difference between precipitation and evaporation were analyzed.The responses of climatic drought to climate warming were also researched with aridity index.The results showed that climatic changes were taken on warm and dry trend during recent 40 years in eastern Liaoning,namely,air temperature was rising and precipitation was decreasing,especially in the 1990s.The climatic changes would expedite the degree of drought in eastern Liaoning province.
