摘要
利用无锡市1959-2003年的逐日平均气温和逐日最高、最低气温资料，采用线性拟合和谐波分析等方法分析了无锡气温和气温变化的基本特征。针对气温异常的冬季和夏季，给出了典型距平场。经过分析认为，形势场异常在一定程度上决定了气温演变。在分析气温变化原因时，着重比较了城市化和观测环境恶化对气温的影响。
Based on the temperature from 1959 to 2003,the characteristics of climatic change in Wuxi are analyzed. The results show that the temperature for the last 45 a appears to be going up（0. 025（C/a）, especially in the last 10 a. Aiming at cold or hot winter and summer, four deflection fields are drawn. Position field is considered to have decided the climatic change to some extent. The cause of the climatic change is analyzed , and the effects of urbanization and environment-worsening are compared.
