1、實(shí)用文檔摘要本文選取1951-2010年濟(jì)南市54823地面觀測(cè)站的平均氣溫（月平均氣溫和年平均氣溫）、年平均最高和最低氣溫、年極端最高和最低氣溫?cái)?shù)據(jù)資料，采用線性趨勢(shì)、距平、滑動(dòng)平均等統(tǒng)計(jì)分析方法，對(duì)近60年來(lái)濟(jì)南市的平均氣溫、最高和最低氣溫、極端氣溫的變化特征進(jìn)行分析，進(jìn)而分析其影響因素及年代際變化特征。結(jié)果顯示：近60年來(lái)濟(jì)南市的平均氣溫、最高和最低氣溫均呈波動(dòng)式緩慢上升趨勢(shì)，且升溫態(tài)勢(shì)明顯，尤以極端最低氣溫增幅最大。從季節(jié)變化來(lái)看，四季的氣溫變化也呈現(xiàn)出波動(dòng)式上升態(tài)勢(shì)，尤其冬季氣溫增長(zhǎng)幅度最大。由于濟(jì)南市的城市
2、化進(jìn)程不斷加快，城市人口不斷增加，導(dǎo)致城市熱島效應(yīng)加劇，因此濟(jì)南市的氣溫也在不斷升高。通過(guò)研究，揭示了濟(jì)南市的氣候變化規(guī)律，為了解濟(jì)南地區(qū)的長(zhǎng)期氣候變化趨勢(shì)及其是否與全球氣候變暖的背景相一致提供理論依據(jù)，同時(shí)有助于全面了解濟(jì)南的氣溫變化特征。對(duì)氣候影響因素進(jìn)行分析，可以有效地預(yù)測(cè)氣候?yàn)?zāi)害，對(duì)防災(zāi)減災(zāi)有重要作用。關(guān)鍵詞：平均氣溫；最高氣溫；最低氣溫；極端氣溫；變化特征大全實(shí)用文檔ABSTRACTThispaperselectsthedataofthe54823ground-basedobservatoriesinJina
