- 摘要:
- 干旱的发生不仅影响到当地的农业生产，还极大的破坏了当地的生态环境。采用MODIS数据以条件植被温度指数（VTCI）作为旱情指标，对湖南省2005年7月下旬的旱情分布进行了监测。综合考虑了归一化植被指数（NDVI）和增强型植被指数（EVI）的优劣性之后，以EVI代替NDVI构建了EVI-Ts特征空间，其中采用分裂窗算法对陆地表面温度进行了反演，最终得到了与实际旱情大致相符的旱情分布图。研究表明：此种方法适用于湖南省的旱情监测，同时它也是一种便捷、高效的大面积与近实时监测方法。
- Abstract:
- The occurrence of drought not only affects the local agricultural production but also greatly damages the local ecological environment. This study based on MODIS data monitors the distribution of drought in Hu’nan province in late July 2005, using vegetation temperature condition index (VTCI) as drought indicator. Considering the advantages and disadvantages of the normalized difference vegetation index (NDVI) and enhanced vegetation index (EVI), using EVI instead of NDVI to establish EVI-Ts space and the Split-Window Algorithm to retrieve land surface temperature, the final distribution of drought is broadly in line with the actual situation. This study showed that this method is suitable for monitoring drought in Hu’nan province and is also convenient, efficient and near-real time drought monitoring approach which may be used to monitor in the wide range.
