%X 本文选取甘肃省平凉市崆峒站点，利用站点1960~2019年间的逐日平均气温资料，计算该站点的≥0℃和≥10℃活动积温，以及初、终日和持续天数，分析该地区的热量资源变化特征。结果显示：近60a崆峒地区≥0℃和≥10℃的活动积温呈显著增加趋势；≥0℃和≥10℃活动积温初日均提前，终日有推后，但趋势较初日弱。崆峒地区 ≥ 0℃和≥10℃的活动积温持续天数也有延长，其中≥10℃的活动积温持续天数增加趋势较≥0℃活动积温持续天数更为明显。对≥0℃和≥10℃的活动积温进行M-K检验得到，崆峒 ≥ 0℃积温突变年份为1997年，对于≥10℃积温，突变年份为1995年，突变后的活动积温都有大幅上升。<br />
This paper selected Kongtong Station in Pingliang City, Gansu Province, and used the daily average temperature data of the station from 1960 to 2019 to calculate the active accumulated temperature of ≥0？C and ≥10？C at the station, as well as the first date, the last date and lasting days, to analyze the characteristics of the change of heat resources in the region. The results showed that the active accumulated temperature of ≥0？C and ≥10？C in Kongtong area had significantly increased in recent 60 years. The first date of activity accumulated temperature ≥0？C and ≥10？C was earlier than the first date, and the last date was later, but the trend was weaker than the first date. The duration of active accumulated temperature ≥0？C and ≥10？C in Kongtong area had also been prolonged, and the increasing trend of the duration of active accumulated temperature ≥10？C was more obvious than that of active accumulated temperature ≥0？C. M-K test on the active accumulated temperature ≥0？C and ≥10？C showed that the abrupt change year of the accumulated temperature ≥0？C in Kongtong was 1997, and the abrupt change year of the accumulated temperature ≥10？C was 1995. The active accumulated temperature after the abrupt change had increased significantly.
