| 摘 要： | 为探究山东省气温和降水的时空变化特征及其对ENSO事件的响应，基于1961—2012年山东省18个气象站点的气温、降水数据与表征ENSO的海温距平和南方涛动指数，通过时序变化与突变检验、空间插值及相关性分析等方法，研究山东省气候变化的时空特征以及其与ENSO的关系。结果表明：（1）1961—2012年山东省年、季节气温均呈明显的波动上升趋势，并于1988年发生增温突变，其中年均温以0.025℃/a的速率递增，冬季气温以0.04℃/a的速率成为增温趋势最为明显的季节。年、季节降水量呈波动减少趋势，年降水量以-1.60 mm/a的速率递减，夏季降水减幅最大，其速率达到-1.07 mm/a。此外，气温增幅和降水量减幅均表现出沿海大于内陆、平原大于山区的特点。（2）ENSO强度对山东省气温变化影响并不显著，而与其降水量变化显著负相关，其中，中、强等级的ENSO事件对年降水量的作用更明显。（3）ENSO强度对气温的影响大致呈由西北向东南递减的规律，对降水的影响则由沿海向内陆递减，并受地形影响，体现出非地带性特点。

| Abstract: | In order to analyze the spatial-temporal variation of temperature and precipitation in Shandong Province and its response to ENSO events, based on the SSTA and SOI data which characterize the ENSO events, and temperature and precipitation data derived from 18 meteorological stations in Shandong Province from 1961 to 2012, we used the climate tendency rate and the moving average, Mann-Kendall mutation test, inverse distance weighted interpolation method and correlation analysis to analyze spatial-temporal characteristics of climate change of Shandong Province, and its correlation with ENSO event. The results showed that: (1) annual and seasonal temperature of Shandong Province showed significant fluctuation and rising tendency from 1961 to 2012, and warming mutation occurred in 1988, the annual temperature increased at a rate of 0.025℃/a, winter’s warming trend was most obvious at a rate of 0.04℃/a; annual and seasonal precipitation decreased in fluctuation, annual precipitation decreased at a rate of -1.60 mm/a, and the largest decrease occurred in summer at a rate of -1.07 mm/a; besides, both the temperature’s increase and precipitation’s decrease showed the characteristic of coastal regions greater than inland areas, mountainous areas greater than plain areas; (2)the correlation between the intensity of ENSO events and temperature changes of Shandong Province was not significant, but there was significantly negative correlation between theintensity of ENSO events and precipitation, and the effect of moderate and severe intensity ENSO events on the annual precipitation was more pronounced; (3)the impact of the intensity of ENSO events on temperature spatial distribution showed decreasing trend from northwest to southeast roughly; and its effect on precipitation decreased from the coastal to the inland, and was affected by higher terrain factors, reflecting the non-zonal characteristics. |
