摘要
利用2011年各月的MODIS数据,反演得到青岛地区地表温度数据和植被覆盖数据,对其地表温度与植被覆盖的分布状况及相互关系进行定量研究。实验表明,青岛市存在热岛效应,且热岛效应夏秋季节在市区表现较为明显,在夏秋季节内地表温度与植被覆盖之间呈现显著的负相关关系。此外,还对比了青岛市与上海市的城市热岛效应的不同,对青岛市热岛效应非一致性作出进一步分析。
In this paper,we used MODIS data of Qingdao for each month of the year 2011 to derive surface temperature data and vegetation data.We had a quantitative research on the distribution and the relationships between the land surface temperature and vegetation coverage.Experiments show that,the existence of the heat island effect in the urban area of Qingdao and it is obvious in summer and autumn which has a significant negative correlation in the surface temperature and vegetation.In addition,we also compared the urban heat island effect in Shanghai,and had a further inconsistency analysis of the urban heat island effect in Qingdao.
