| 摘 要： | 为了深入认识全球气候变化背景下区域气温、降水响应及变化趋势，通过采用距平分析、线性趋势法、5年滑动平均、Mann-Kendall突变检验以及滑动t检验方法，分析近50年陕西省气温降水的年际和季节变化特征。结果表明，陕西省1960—2009年气温的年际和季节变化以年平均气温、春季、秋季和冬季平均气温的显著升高、及冬季和秋季的较早增暖突变为特征；降水量的年际和季节变化以年降水量、春季和秋季降水量显著减少，夏季和冬季降水量显著增加，以及春季降水量的较迟减少突变、夏季降水量的较早增加突变为特征。近50年陕西省气温降水年际和季节变化趋势符合中国气候变化的总体趋势。

| Abstract: | In order to identify the responses and change trends of temperature and precipitation in regional area under global climate change, methods of linear trend, 5-years moving average methods, Mann-Kendall nonparametric test, moving t-test were employed to examine temperature and precipitation change trends, mutation in temperature and precipitation at inter-annual and seasonal scales across the Shaanxi Province during 1960 to 2009. Results showed that, the characteristics of temperature at inter-annual and seasonal scale were average temperature of annual, spring, autumn and winter increased significantly, earlier warming mutation in winter and autumn from 1960 to 2009 in Shaanxi Province. The characteristic of precipitation at inter-annual and seasonal scale was annual rainfall, spring rainfall and autumn rainfall reduced significantly, while summer rainfall and winter rainfall increased significantly. And spring rainfall mutation with reducing late, while summer rainfall mutation with increased earlier was characterized. The inter-annual and seasonal change trends of temperature and Precipitation in Shaanxi Province were consistent with the overall trends of climate change in China. |
