 Taking Mongolia plateau as a study area, make use of the temperature and vegetation products of the EOS/MODIS data to calculate four index they are vegetation condition index (VCI) and temperature condition index (TCI) and vegetation health index (VHI) and vegetation supply water index (VSWI). Mapped the Mongolia plateau for 2003-2013 growing season (from May to September) time and space distribution of drought. SPSS software is used to analyze the various index and the correlation between

The results showed: VHI and VSWI index relative to other two indexes is applicable to the Mongolian plateau drought monitoring. Plateau; EOS/MODIS time sequence 摘要 以蒙古高原为研究区, 利用了美国国家航空航 天局(NASA)研究生产的蒙古高原研究区范 围内的 2003~2013 年生长季(每年 5~9 月) 的 132 景 MYD13C2 和 MYD11C3 数据计算了 植被条件指数 (VCI) 、 条件温度指数 (TCI)、 植被健康指数 (VHI) 和植被供水指数 (VSWI) 等四个指数的干旱的时空分布情况, 监测结果 与 10cm 土壤相对湿度数据进行相关性分析, 从而选择最适用于蒙古高原的旱情遥感监测 的指数。结果表明,VCI、TCI、VHI,VSWI 四个指数与 10cm 土壤相对湿度的相关系数均 以通过了 0.01 的显著性检验。其中,VHI 与 VSWI 两个指数在时空上都有较好的较稳定。 关键词:遥感;干旱监测;相关性分析;蒙古 高原;EOS/MODIS 时间序列 1. 引言
