摘要
利用1970—2007年苏州城市及近郊县(市)气象站观测资料,结合Landsat 5卫星反演资料,统计分析城市化进程,对苏州区域气候变化的影响。分析结果表明:从1990s中后期开始,随着经济发展,苏州城市建设速度明显加快,城市化进程对苏州气候影响明显,城、郊气温均有明显的上升趋势,相对湿度呈现下降趋势,降水量整体上呈现上升的趋势,日照时数有明显的下降的趋势;苏州城市热岛效应显现、城市霾出现、太湖蓝藻爆发、极端气候事件增多,也与快速的城市化进程有着一定的关系。
Using weather observation data of Suzhou and nearly suburban county （city） weather sta- tions, combined with Landsat 5 satellite data, the urbanization and the law of climate change were ana- lyzed. The results show that from the 1990s,Suzhou city construction speed increases. Urbanization obvi- ously influences climate change. The temperature has significant upward tendency, the relative humidity is opposite, the rainfall amount is going up, and the sunshine duration tends to decrease. Suzhou city heat island effect, city haze, blue-green algae bloom in Taiha, extreme weather events can be explained by the urbanization construction.
