摘要
利用2014年09月11日Landsat-8 OLI/TIRS影像数据,以安徽省马鞍山为研究区,使用ENVI5.1遥感图像处理软件,对Landsat-8影像的TIRS10波段使用单窗算法进行地表亮度温度反演,再对OLI多光谱影像使用神经网络法进行土地利用/覆盖分类,并利用GIS空间分析和数理统计方法对芜湖市城市热岛效应与土地利用/覆盖的关系进行定量研究分析。研究结果表明:(1)马鞍山城市中心区地表亮度温度明显高于市郊,强热岛区与热岛区面积共12.80km2,占研究区总面积的1.21%,城市热岛效应存在但不显著;(2)土地利用/覆盖类型不同,地表亮度温度差异明显;(3)建设用地表面温度相对较高,是城市热岛效应强度增加的主要影响因素,而林地和水体面积的增加能有效缓解城市热岛效应的强度。
According to landsat- 8 OLI/TIRS image data on September 11,2014 of Ma'anshan City of Anhui province as the research area,ENVI5. 1 remote sensing image processing software,band TIRS10 images of the landsat8 using mono window algorithm for land surface brightness temperature inversion,and oli multispectral images using neural network method of land use/cover classification are used,and the GIS spatial analysis and mathematical statistics method of Ma'anshan City,the urban heat island effect and land use/coverage for quantitative analysis are taken. The results show that:( 1) Ma'anshan city center area surface brightness temperature is obviously higher than that of the suburb and strong heat island area and heat island area is 12. 80km2 accounted for 1. 21% of the total area of the study area,the urban heat island effect exists but is not significant;( 2)land use/covering different types,land surface brightness temperature difference is obvious;( 3) construction land surface temperature is relatively high to increase the intensity of urban heat island effect of main influence factors,and woodland and water area increase can effectively alleviate the intensity of the urban heat island effect.
