| 摘 要： | 以三江源自然保护区为研究区，基于MODIS L1 B数据，采用劈窗算法反演地表温度，分析了地表温度空间分布的特征，与计算得到的归一化植被指数进行回归分析。结果表明地表温度与归一化植被指数存在很好的负相关性。分析讨论了地表温度的空间分布与土地覆盖及其他影响因子之间存在的定量关系，探讨了植被生产力与气候变化之间的相互作用以及发展趋势。研究结果有利于三江源湿地的生态保护，可为土地覆盖的动态监测提供有力的科学参考。

| Abstract: | Based on MODIS L1B data, the land surface temperature is retrieved by split -window algorithm, the characteristic of the spatial distribution of surface temperature is analyzed .In this study, the three -river source region nature reserve is chosen as the study area.The results indicate the land surface temperature has a great negative relation with the normalized difference vegetation in -dex.The research is discussed between spatial distribution of the surface temperature and the land cover as well as other affecting fac -tors about the quantitative relationship by vector masking and statistical analyzing , explored the interaction and development trend be-tween vegetation productivity and climate change .This result is helpful to the ecological protection of the three -river source region that would provide powerful scientific reference and basis for decision making for dynamic test of the land cover . |
