摘　　要：为了研究气候变暖背景下10℃界限温度的变化规律,用现代气候变化理论与数理统计方法,分析陕西关中西部近50年日平均气温稳定通过10℃的初终日期、间隔日数及其积温变化特征。结果表明:关中西部日平均气温≥10℃的初日呈显著提早趋势,终日呈波动推迟趋势。初终日之间间隔日数显著增加。≥10℃期间的积温以56.568℃·d/10 a的幅度显著增加。积温年代际波动增加,冷暖交替频繁。In order to study under the background of climate warming, 10℃ temperature variation characteristics, analyze Western Guanzhong in Shaanxi Province from 1961 to 2010, the average temperature stability by 10℃ at the beginning of the day, all day long, interval number and its change characteristics of accumulated temperature. The results showed that： Baoji Shaanxi, the average temperature of 10℃ or more significant early trend in the early days, all showed a trend of fluctuations delay. Early all day long interval between days increased significantly. During the acuity 10℃ accumulated temperature of 56.568℃.d/10 a significantly increased. Accumulated decadal fluctuations increased, frequently alternating cold and warm.
