摘要:

为了鉴别人类活动,特别是气象观测环境城市化对气温变化趋势和定量变化的影响特点,以达到客观分析气候变暖的目的,笔者利用1952—2009年西峰、平凉与1968—2009年环县气温资料,以位于甘肃省庆阳市的西峰基准站1997年观测环境明显城市化为界限,通过计算分析气候趋势系数和线性回归方程倾向率等,判别城市热岛效应对西峰站气温序列的影响作用。结果表明:西峰基准站的年平均气温和年平均最低气温的变暖趋势比平凉和环县更为明显;西峰年平均最高气温在南北方向上与平凉和环县比较,并无一致性显著影响。西峰站年平均气温线性倾向率分别比平凉站、环县增加0.051℃/10 a、0.111℃/10 a;西峰站年平均最低气温线性倾向率分别比平凉站、环县站增加0.279℃/10 a、0.478/10 a;就年平均最高气温的线性倾向率而言,与环县相比,城市化环境对西峰具有一定的影响,西峰与平凉站相比无明显差别。关键词:观测环境;城市化;气温;均一性;影响.

Abstract:

To identify the impact of human on trends of temperature variation and achieve the objective results of global warming, the temperature data in Xifeng from 1952 to 2009, in Huanxian and Pingliang from 1968 to 2009 had been used. We identified 1997 as start point of obvious urbanization in Xifeng and analyzed the climate tendency coefficient and trend rate of linear regression equation. The results showed that the rising trends of annual mean temperature and annual mean minimum temperature warming in Xifeng were more obvious than in Pingliang and Huanxian. There was no consistency of average maximum temperature in Xifeng and Pingliang, Huanxian from the northern to southern, linear trend rate of average temperature of Xifeng was 0.051℃/10 a above than Pingliang’s and 0.111℃/10 a above than Huanxian. The linear trend rate of average minimum temperature of Xifeng was 0.279℃/10 a above than Pingliang’s and 0.478℃/10 a above than Huanxian’s. As for the linear trend rate of maximum temperature, the impact of urbanization was more obvious in Xifeng than Huanxian, and there was no significant difference between Xifeng and Pingliang.Key words: observation environment; urbanization; temperature; Homogeneity; affect
