| 摘 要： | 利用1997-2006年8km空间分辨率的AVHRR/NDVI,得到了与区域气候模式RegCM3具有相同分辨率的植被覆盖度时间序列,并用其替代RegCM3模式中默认的植被覆盖度,对黄河源区主要气候要素进行了数值模拟。结果表明,使用卫星遥感估算的植被覆盖度,模拟的黄河源区气象台站月平均气温更接近实测值,局地降水量也有一定...

| Abstract: | Based on AVHRR/NDVI of 8 km spatial resolution from 1997 to 2006,a fractional vegetation cover data were obtained,which has the same spatial resolution with Regional Climate Model(RegCM3).Using the derived fractional vegetation cover instead of the default fractional vegetation cover in RegCM3,the main climatologic elements in the source water region of the Yellows River were simulated.The results showed that,with considerating the fractional vegetation cover derived satellite in the model,the simulated mon... |
