| 摘 要： | 应用美国陆地资源卫星Landsat ETM＋影像资料,反演了江门市区的地表温度（LST）,并提取研究区的NDVI、NDBI和MNDWI指数。分析了江门市区冬季LST的空间分布特征及城市地表热环境与土地覆盖类型之间的关系。结果表明：江门市区LST分布具有空间差异性,不同土地覆盖类型有较大差异,存在城市热岛效应;LST与3种归一化指数存在相关性,其中LST与NDVI存在非线性相关、与NDBI存在线性正相关、与MNDWI存在线性负相关。 |
| 关 键 词： | 遥感 地表温度 归一化指数 土地覆盖类型 江门市区 |

| Abstract: | Applying Landsat ETM+ image data of U.S.land resource satellites,the land surface temperature(LST) of Jiangmen city was achieved by inversion,and the NDVI,NDBI and MNDWI indices on that area were extracted.The LST's spatial distribution of Jiangmen city during winter was analyzed,and the relationship between land surface thermal environment and cover types of that area was studied.The results were showing as follows.There are spatial differentials for the distribution of LST of Jiangmen city.For different l... |
