摘要: 根据1954—2005年锦州累年逐月平均气温资料,采用一元线性趋势估计和滑动平均方法分析了近半个世纪锦州季和年平均气温变化趋势;采用滑动t检验法分析了气温突变。结果表明:近半个世纪锦州气温变化呈明显上升趋势,20世纪80年代后期气温发生突变,其后气温持续偏高;同时根据锦州城郊农业试验站的资料,初步分析了城市热环境对气温的影响。分析表明,人为的城市热环境是自20世纪80年代以来锦州气温偏高的主要原因之一。

关键词: 气温, 线性趋势估计, 滑动t检验法

Abstract: Based on monthly average air temperature data in Jinzhou from 1954 to 2005,the seasonal and annual average air temperature changes were analyzed by linear trend method and moving average method.At the same time,the abrupt change of air temperature was determined by sliding t-test method.The results indicate that air temperature change takes on an obvious ascending trend during the recent 50 years in Jinzhou.The abrupt change of air temperature appears in the late 1980s.Since then,air temperature always keeps the higher value.According to agricultural station data in the suburb,the effect of urban heat environment on air temperature was analyzed.It states that the effect of urban heat environment on air temperature is one of main reasons causing higher temperature in Jinzhou since the 1980s.
