摘要
针对现有兰州市城市热岛效应研究多以地面气象站的观测资料为数据源,以遥感影像为数据源较少的现状,该文利用Landsat 8影像,研究了兰州市城市热岛效应与修改后的土壤调节植被指数(MSAVI)、增强型水体指数(EWI)、土壤亮度指数(NDSI)、土壤湿度指数(NDMI)之间的关系。结果表明,兰州城市热岛效应较为严重,城市热岛效应与土壤湿度指数、增强型水体指数、土壤亮度指数呈正相关,与修改后的土壤调节植被指数呈负相关。
Since most of the existing Lanzhou urban heat island research uses ground weather station observation data as data source, few research uses remote sensing image data, this paper studied the rela- tionship between the urban heat island effect and the MSAVI, EWI, NDSI and NDMI in Lanzhou city based on Landsat 8 images. The results showed that there was obvious heat island effect in Lanzhou. And the heat island effect was positively correlated with NDMI, EWI and NDSI, but negatively correlated with MSAVI.
