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6．752min／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。
In this paper, the air temperature and precipitation data in Xi＇an during 1951-2005 are used to analyze the changea- ble trend of the climate in Xi＇ an city in recent 60 years. The main results are obtained as follows ： （1）The annual average air tempera- ture 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 inereased by 0.081℃. The coldest and hottest years occurred in 1954 and 2002 respectively; （2）The decadal annual precipitation is decreased by 6. 752 mm. However, winter precipitation has an upward trend; （3）The arid and warming trends of the elimate in Xi＇ an in nearly 60 years make the local climate more continental and vulnerable.
