摘要
降雨作为产汇流的驱动因子之一,其时间和空间的变化影响着产汇流规律.利用黄河源区1993年、1995年、1997年与1998年NOAA-AVHRR遥感数据以及同期的降雨观测资料,分析了降雨的空间分布和洪水的相关性,同时也分析了黄河源区降雨的时间变化规律和空间分异特点.
The convergent flow production law was influenced by their temporal and special variation with rainfall as one of the drive factors of convergent flow production NOAA/AVHRR-LAC remote sensing data of these regions in 1993, 1995 - 1997 and 1998 were utilized to calculate the rainfall data and the observed data of the same time; the relativity of the rainfall spatial distribution and the flood was analyzed; meanwhile the temporal variation law and the special different character of the rainfall in the source regions of Yellow River were analyzed.
