摘要
随着城市化发展,城市建筑用地的增多对区域气候环境造成重要影响。文章通过对2010年4个月份的MODIS数据进行预处理,反演提取出青岛市区的城市归一化建筑指数以及地表温度数据,并对两者间之间的相关关系进行了研究。研究结果表明:城市建筑用地率(归一化城市建筑指数)越高的地区,城市的地表温度越高,热岛效应就越明显。同时,归一化城市建筑指数与地表温度的相关性的空间分布规律也为有效改善城市环境提供了借鉴依据。
The city's development and the increase of city construction land have important influences on regional climate environment. Based on MODIS data in 2010 four month pretreatment, this paper extracts city normalized construction index and surface temperature data in urban area of Qingdao and analyses the correlation between them. The results show that: the higher the city building land rate(normalized city building index)be, the higher surface temperature is and the heat island effect is more obvious. Meanwhile, the normalized index of city buildings and surface temperature distribution of spatial correlation also provides a reference for the effective improvement of the urban environment.
