| 摘 要： | 绿洲空间热环境的研究是深入了解绿洲沙漠化变化机理的重要手段。以土库曼斯坦马雷绿洲为例,将Landsat TM/ETM+作为基础数据源,基于定量遥感分析方法,进行马雷绿洲地表温度以及植被覆盖度的反演,在统计地表温度—植被覆盖度二维散点图的基础上,研究地表温度与植被覆盖度的相关关系。结果表明:土地利用类型是影响地表温度的显著因素,基本决定地表温度的总体分布的是土地利用类型的分布;通过对地表温度以及植被覆盖度相关性的研究,得到2001及2010年的相关系数分别为0.677 8、0.665 0。

| Abstract: | Abstract The study on oasis thermal environment is important for understanding of oasis desertification mechanism of change. With Mary Oasis of Turkmenistan as an example, using Landsat TM / ETM ＋ as the data source, Mary Oasis＇ s land surface temperature and vegetation cover were inverted with quantitative remote sensing analysis method. The correlation between vegetation coverage and land surface temperature on the basis of two-dlmensional scatter diagram of vegetation coverage and land surface was studied. The results showed that ： the land surface tempera- ture is determined obviously by land surface type and the land surface type distribution influences the overall distribution of land temperature; Through the study on correlation between vegetation coverage and land surface temperature, it was obtained that the correlation coefficients in 2001 and 2010 reached O. 677 8.0. 665 O. |
