中国大陆雨涝时空特征
Temporal and Spatial Characteristics of Waterlogging over Mainland China
摘要
Abstract
The characteristics of the waterlogging over mainland China are analyzed by using the daily station rain gauge data.The results show that waterlogging mainly occurs in summer over most regions of China,while of-ten occurs in southern coastal area and Hainan province in autumn.Using the agricultural disaster statistics data, the waterlogging indexes are further accessed.A strong correlation is found between annual waterlogging station rate and annual floods affected crop area.This suggests that the waterlogging indexes have practical implications.Be-cause the floods always bound up with river basin,the waterlogging and its change characteristics are also analyzed. Higher waterlogging station rate is found over river basins of Yangtze River,Pearl River and Huai River basin and the lowest is over Yellow river basin.The interdecadal variation of waterlogging is obvious,but the trend is not sig-nificant.关键词
