摘要:

 通过分析陕西省近60 a 来气温时空变化特征,结合GIS 空间分析技术,对中国陕西省气温变化进行定量化分析,阐述其时空演变规律。结果表明: 近60 a 来陕西省气温总体呈上升趋势,升温趋势较缓和的是关中地区,陕北地区升温趋势明显; 在时间尺度上,从20 世纪90 年代以来陕西省气温的上升趋势特别显著; 陕西省各区年均气温变化具有明显的周期性,分别以10 a 为第一主周期。

关键词: 陕西省, 气温, 时空变化, 突变, 周期
 

Abstract:

Through analysis of the spatial and temporal variation of temperature in Shaanxi Province in recent 60 years,the temperature variation was quantificationally revealed by combining GIS analysis method in this paper. Results show that the air temperature presented increasing trend in the rencent 60 years as a whole but in the middle of Shaanxi Province warming trend was not so significant,but in the north region of Shaanxi Province warming trend was obvious. The rising trend of temperature since the 1990s was especially remarkable in Shaanxi Province. There was obvious ten - year cycle change of annual air temperature in Shaanxi Province.

Key words: Shannxi Province, air temperature, spatio - temporal change, mutation, cycle
