摘    要:针对全球气温升高、气候变化导致降雨发生变化、极端事件频发问题,选用珠江流域中佛冈县作为研究区域,统计了1960--2009年佛冈县50年逐日降雨资料,发现佛冈县年总降雨近50年有所减小,尤其是5月和10月降雨量存在减少趋势,目最大降雨量也存在减小趋势,说明降雨减小的原因主要是暴雨量减小。由于降雨的减少主要是暴雨的减少所致,说明气候变化有可能降低佛冈县发生洪涝灾害的概率。

关 键 词:气候变化  降雨  特征  趋势  佛冈

Abstract:The global warming and climate change has changed the pattern of precipitation and the extreme weather has been frequently witnessed. Fogang County has been selected as the pilot site and the statistics of the daily precipitation data during 1960 - 2009 has shown the rainfall has reduced in recent 50 years. This changing trend has been more obvious in May and October. The maximum daily rainfall has shown the same reducing trend, indicating that the reduction of the storm rain may be the main reason of the abatements. It may imply that the climate change will lower the occurrence frequency of flood disasters in Fogang County.
Keywords:climate change  precipitation  characters  trend  Fogang
