Relationships between Horqin meadow NDVI and meteorological factors
科尔沁草甸草地归一化植被指数与气象因子的关系
The results showed that the seasonal variation of NDVI demonstrated a stronger relationship with water vapor pressure than with precipitation, when the meadow have high underground water level.
利用内蒙古科左后旗草甸草地2000—2006年MODIS的8d合成NDVI(归一化植被指数)资料和逐日气象资料,分析了NDVI的季节变化和年际变化特点以及NDVI与气象因子的关系,发现如下主要规律:季节变化过程中,草甸草地较高的地下水位使得降水量对NDVI的影响低于水汽压的影响;积温和累积降水量共同控制着各年草地的返青速度,草地增长期(6、7月)的降水量对NDVI年最大值的影响比年总降水量更显著;时滞分析表明,水汽压持续影响到之后约12d的NDVI,平均气温的时滞为11—15d,降水量对NDVI影响的累积时滞双重效应可达36—52d。
