摘　　要：城市化发展对城市气候及环境的影响已成为气候变暖研究中最受关注的问题之一。基于1961—2013年福建省福州和漳州的城郊逐月气温观测数据和同时期的NCEP/NCAR R1再分析气温资料,通过线性回归、OMR方法等对两地平均气温、最高气温以及最低气温进行分析。着重探索不同城市化程度对气温变化的影响差异。结果表明,不同城市化程度的地区城郊气温差ΔT的大幅度变化存在时间差;随着城市化程度的加深,城市气温受下垫面的影响越大;不同城市化程度的地区平均气温、最低气温、最高气温以及四季气温受到城市化影响所导致结果各异。Urbanization has brought a series of environmental problems and changed the local microclimate.This brings great challenges to human health and sustainable development.This study explored the response trend of urban and suburban temperature in different urbanization process in Fuzhou and Zhangzhou during 1961-2013 based on land surface temperature and NCEP/NCAR R1 reanalysis temperature data.The linear regression and OMR methods were used to analyze the difference in the effect of different urbanization level on air temperature.Our results show that there is a time difference between the significant changes ofΔT in the two cities.With the development of urbanization,the temperature is affected by the influence of the underlying surface.The urban average temperature,minimum temperature,maximum temperature and seasonal temperature vary with different urbanization level.
