摘要
根据1960—2010年大渡河上游逐日降水资料及汛期标准,运用气候倾向率、小波分析法,分析了这50年来大渡河上游汛期降水日数的时空分布特征。
Based on the daily precipitation data and flood season standard in the upper reaches of Dadu River from 1960 to 2010, the temporal and spatial distribution characteristics of precipitation days in the upper reaches of Dadu River in flood season during recent 50 years were analyzed by using climatic tendency rate and wavelet analysis method.
