摘要：Rainfall-triggered landslides in the Three Gorges Reservoir Region are related to two rainfall patterns: rainstorm event and long-lasting moderate precipitation event. Trends of the two rainfall patterns are investigated using trend estimation and Mann-Kendall test. For this purpose, the daily rainfall data are obtained from the Yichang station, the Enshi station and the Chongqing station for the period 1952-2011. The results of the trend estimation show that annual average number of rainstorm events increase at the three stations during the period, while opposite trends in long-lasting moderate precipitation events is observed. However, the increasing and decreasing trends are not significant in the Mann-Kendall test.
