摘要:
利用吐鲁番市城区站(51573站)和郊区站(51572站)的1974~2013年气温资料，使用线性趋势分析、累积距平等方法对近40 a吐鲁番市城郊年平均气温、年平均最高气温和年平均最低气温进行分析，从而了解吐鲁番市热岛效应的变化情况。结果表明：近40 a吐鲁番市热岛强度有逐渐增强的趋势，热岛效应对年平均最低气温的影响最大，年平均气温次之，年平均最高气温最小。城区年平均最低气温、年平均气温、年平均最高气温分别较郊区增多1.7℃、1.074℃、0.18℃，并分别于1998年、2000年、2006年发生了由冷岛效应向热岛效应的突变。
Based on temperature data from Urban (51573 station) and suburban areas (51572 station) in Turpan City from 1974 to 2013, the change characteristics of annual mean temperature, annual mean maximum temperature and annual mean minimum temperature were analyzed by using the methods of linear regression and accumulative anomaly on heat-island effect the suburb in Turpan city nearly 40 a. The main results showed: The intensity of heat-island has had gradually increasing in Turpan nearly 40 a, the impact of the heat-island effect on the average minimum temperature is fastest. The annual average temperature is in second place, and average maximum temperature is the slowest. These three key factors of the city compared with the suburbs increased respectively in 1.7˚C, 1.074˚C and 0.18˚C, and they had mutation in1998, 2000 and 2006 respectively from cold island-effect to heat-island effect.
