中文摘要：

利用7种极端降雨指标分析评估TRMM 3B42、TRMM3B42RT及CMORPH这3种主要的卫星降水产品在中国地区的表现。为全面、科学地评估这些产品，采用不同的时间尺度、空间尺度以及评价指标来作检验，结果表明：1）总体上3B42的表现比3B42RT和CMORPH要好，3B42RT倾向于高估，而CMORPH则倾向于低估；2）在对极端降雨量的表现中，3种产品对喜马拉雅山脉地区都存在着高估现象，并在春季的表现最好；3）在对极端降雨强度的表现中，3种卫星降水产品对PRCPTOT的表现更好，尤其在全中国和西部；4）在对周期的表现上，3种产品对海拔较高的地方均有着显著地高估，另外，CMORPH对海拔较低的地方同样存在着高估的现象，3种产品对CWD的表现更好。在中国极端降雨的探测上，3B42要优于3B42RT和CMORPH，但是它们对海拔较高的地方均存在一定程度的高估，因此在这些地方使用时要谨慎。

英文摘要：

Climate change may have a serious impact on human society and the natural system. In recent years, extreme weather events have occurred frequently, and the global temperature and rainfall extreme values have been significantly changed. In order to reduce the direct or indirect loss caused by extreme events, especially extreme rainfall events, it is extremely important to strengthen the study of extreme rainfall. With the development of meteorological satellites and the development of its technology, it is possible to monitor, invert and integrate precipitation with various detectors carried by satellites, and there are also a variety of high spatial resolution satellite retrieval precipitation products widely used in the fields of hydrology, meteorology, climatology, and water resources management and other fields. Due to a variety of satellite retrieved precipitation products used in satellite data and inversion algorithms are not the same, so their accuracy will be some differences, in view of this, it is necessary to test and evaluate those satellite precipitation products that are widely used and continue to be used in future. Seven extreme rainfall indexes were used to analyze the performance of the three main satellite precipitation products TRMM 3B42, TRMM3B42RT and CMORPH in China. In order to evaluate those products comprehensively and scientifically, different time scales, spatial scales and evaluation indexes were used to test the results, and the following conclusions were obtained： 1） Overall, the performance of 3B42 was better than that of 3B42RT and CMORPH, 3B42RT tends to be overestimated, while CMORPH tends to be underestimated; 2） In the performance of extreme rainfall, the three products are overestimated in the Himalayan region and the best performance in spring; 3） In the performance of extreme rainfall intensity, the three satellite precipitation products on PRCPTOT have better performance, especially in China and west part of China; 4） In the performance of extreme rainfall period
