| 摘 要： | 利用西安市1951~2005年的气象资料,对近60年西安市气候变化及趋势进行分析。结果表明:①西安市近60年来气温呈上升趋势,年平均气温的倾向率为0.081℃/10年,特别是冬暖化程度较大。②西安市年降水量以6.752 mm/10年趋势下降。但冬季降水量有增加趋势。③西安市近60年的暖干化,使得该地气候更具有大陆性及脆弱性。

| Abstract: | In this paper,the air temperature and precipitation data in Xi'an during 1951~2005 are used to analyze the changeable trend of the climate in Xi'an city in recent 60 years.The main results are obtained as follows: ①The annual average air temperature in Xi'an is gradually increased,and the warming trend is significant,especially in winter.The decadal mean annual air temperature in Xi'an is increased by 0.081℃.The coldest and hottest years occurred in 1954 and 2002 respectively;②The decadal annual precipitation is decreased by 6.752 mm.However,winter precipitation has an upward trend;③The arid and warming trends of the climate in Xi'an in nearly 60 years make the local climate more continental and vulnerable. |
