中文摘要: 为了揭示全球气候变暖背景下甘肃省定西市安定区的气候变化趋势,根据安定区地面气象站19702010年逐日气温和降水资料,利用线性回归、滑动平均等方法分析了该地区近41年的气候变化特征,并运用Mann-Kendall检验法对气温和降水量年际变化趋势进行突变检验。结果表明,近41年来,安定区年均温表现为显著的增温趋势(P<0.05),且增温率明显高于全国平均水平,并于1997年发生了突变性的升高;近41年来安定区年平均降水量呈减少趋势,但不显著(P>0.05),也没有发生突变,表明安定区气候基本朝暖干化方向发展。
英文摘要: In order to reveal the climate change characteristics in Anding District, Dingxi in Gansu under the background of global warming, the climate changing characteristics over the last 41 years (from 1970 to 2010) in this area were analyzed by means of linear regression and moving average with the temperature and precipitation data from Anding District meteorological stations. Mann-Kendall test was also employed to identify the mutation point and inter-annual variability tendency in temperature and precipitation. In the recent 41 years, annual temperature in Anding District significantly increased (P <0.05) and the increase rates were significantly higher (P<0.05) than that of national average. The mutation tests showed that the annual mutation points of temperature was 1997. The annual precipitation decreased without significance and did not have a mutation point. All of these results revealed that the climate of Anding District was becoming warmer and drier.
