摘要
[目的]研究城市化对石家庄市气温变化的影响,以及利用探空资料进行城市化影响研究的适用性.[方法]基于1981～2010年的逐月探空资料和地面观测资料,研究城市化对石家庄市气温变化影响的性质和程度.[结果]1981～2010年,石家庄市增温趋势达到0.59℃/10a,探空资料增温趋势为0.40℃/10a;其中冬季增温最为明显;城市热岛效应导致石家庄气温增温幅度为0.19℃/10a;夏秋两季城市热岛对季节的增温作用较大;探空资料分离出的城市热岛增温贡献率为32.22％.[结论]城市化对石家庄市气温增暖贡献较为显著.
Abstract
[Objective] The aim was to study effects of urbanization on temperature changes in Shijiazhuang,as well as applicability of upperair observations on carrying out urbanization effect research.[Method] Based on the monthly upper-air observations and air temperature data from 1981 to 2010,the influence property and degree of urbanization on the variation of air temperature in Shijiazhuang was investigated.[Result] The results indicated that the warming trend in Shijiazhuang was remarkable in recent 30 years,which is 0.59 ℃ per decade and for upper-air observations was 0.40 ℃ per decade,and maximum warming rate was occurred in winter;The effect of urbanization to the mean temperature increasing was 0.19 ℃ per decade;The contribution of urbanization effect to seasonal warming was significant in summer and autunn;The contribution rate of the urban heat island effect to mean air temperature was 32.22％.[Conclusion] The contributions of urbanization to air temperature of Shijiazhuang are apparent.
