摘要: 选取山东省德州市为研究区,基于Landsat影像计算地表温度;基于Quickbird影像获取土地利用信息和主要土地利用类型单元的绿地率;在此基础上,对土地利用类型、土地利用单元绿地率与热岛效应之间相关关系进行研究。结果表明:1)研究区土地利用类型及空间结构对城市热岛效应有明显影响;2)居民区用地和道路用地绿地率与地表温度呈明显线性负相关,且稳定性好;工业区绿地率与地表温度也表现出负相关性,但稳定性较差。研究结果可为城市规划和城市绿地建设提供参考。

Abstract: With Dezhou City of Shandong Province as the study area,the urban land surface temperature (LST)was retrieved from Landsat image and land use information and unit greening rate of main land use types were drawn from Quickbird image.The relationship between UHI and land use types and unit greening rate was studied.The results showed that1)Land use types and their spatial structure affect the UHI and its spatial location;2)There was obviously negative linear correlation between the LST and greening rate of residential land and road site,and the stability was very high.There was negative correlation between LST and greening rate of industrial land,but the stability was poor.The study result was meaningful for the urban planning and urban green space construction.

Key words: urban heat island, land use, high spatial resolution image, greening rate
