摘 要: | 研究庐山地区的地表温度,对于本地区的生态保护和开发具有重要意义。本文使用了目标区域内Landsat TM/ETM+从2000~2010年间共8幅影像数据,利用单通道算法和NDVI地表辐射率估算方法反演了区域内的温度场,并生成了历年温度对比效果图。分析推断目标区域内的温度场可能存在一个短年限的温度变化起伏规律,对庐山周边山区的影响有待进一步研究。

Analysis of Land Surface Temperature in Mt.Lu Region through RS Retrieval |

Abstract: | Research of Mt.Lu region temperature distribution will surely benefits the management and development as well as environ-ment protection of this area.In this paper, 8 Landsat TM/ETM +images, ranging from 2000 to 2010, are used to retrieve LST through single-channel algorithm and land surface emissivity ( LSE) estimation from NDVI, which yields thermal maps of those years.The results suggest there may be a circulative change of the whole region temperature, which might be significant in the future, development of this region. |
