摘要
城市温度升高以及大气污染等都会给人类的生产生活带来巨大影响。利用多源遥感数据,采用遥感和GIS技术,对乌鲁木齐市地表温度和气溶胶光学厚度的相关关系进行了研究,结果发现:①乌鲁木齐市日间地表温度月均值7月份最大,12月份最小;夜间地表温度月均值7月份最大,12月份和1月份较小;地表温度夏季最高,冬季最低;2010年、2015年、2020年的年均温有所增高。②乌鲁木齐市气溶胶光学厚度月均值2月份和4月份较大,11月份和1月份较小,气溶胶光学厚度春季最高,夏季最低;年均值变化类似地表温度。③乌鲁木齐市地表温度与气溶胶光学厚度在月、季节与年均呈现显著正相关性。该研究对乌鲁木齐城市环境污染治理具有显示借鉴意义。
Urban temperature rise and air pollution will have a huge impact on human production and life.The correlation between surface temperature and aerosol optical depth in Urumqi was studied by using multi-source remote sensing data and GIS technology.The results show that①The monthly mean daytime land surface temperature in Urumqi was the highest in July and the lowest in December;the land surface temperature is highest in summer and lowest in winter.During the annual change,the surface temperature increased from 2010 to 2020 as a whole.②The monthly mean aerosol optical depth in Urumqi is larger in February and April,and smaller in November and January.The average annual temperature increased in 2010,2015 and 2020.The annual mean changes is similar to the surface temperature.③There was significant positive correlation between surface temperature and aerosol optical depth in monthly,seasonal and annual.This study can be used as a reference for urban environmental pollution control in Urumqi.
