全球变化下的泰山山顶和泰安市气候变化特征对比分析

Nearly 51 Years the Climatic Changes Contrast at Tai'an and Mountain Tai under the Global Change

利用泰安气象局1954年～2005年51年的泰山山顶和泰安市区两个站的气温和降水数据,对泰安市区和泰山山顶的气温和降水特征及变化趋势进行了对比分析,结果发现,泰山山顶气候变化和泰安市区气候变化特征相似,气温明显升高,主要是冬季增温所至,降水波动下降,夏季降水明显减少,受全球气候变化响应显著.不同的是,泰山山顶气温明显低于市区,泰山山顶温度升高的幅度要大于泰安市区的气温升高幅度;而降水除特殊年份外都高于市区,而降水减小的幅度略低于泰安市区.也就是说,相对泰安市区来说,泰山山顶的气候变得更加温暖湿润.

All countries in the world are paying more and more attention to global change. Global change has regional diversity. In order to find out its regional characteristic, statistics, regression and trend analysis are used in this paper. Based on the climate data at Tai＇ an and Mountain tai from 1954 to 2005, the climate change and characteristics in recent 51 years have been analyzed and studied comprehensively. The results indicate that climate in the both regions become warmer and dryer during the last 51 years. The rate of temperature at Taishan summit is higher than Tai＇an urban district and the rate of precipitation at Taishan summit is lower than Tai＇an urban district in recent 51 years.
