摘要
本文以《中国近五百年旱涝分布图集》为基础,并将资料适当延长,提出了流域性洪涝及其指标。在此基础上,初步分析了我国主要流域单元近500年(1470～1991年)和各世纪流域性洪涝事件发生的频次和持续性,并分析了南方、北方和全区域主要流域单元不同等级流域性洪涝空间遭遇的可能性。
Based on the 'Yearly Atlas of Drought/Waterlogging in China for Last 500-year Period', It is prolonged the newly-data to 1991 according to the standard of the Atlas in this paper. The indexes and grades of basin-wide flood as the basis of studying in this paper are proposed. The frequency and succession of basin-wide flood of various river basin units lor different centuries in the last 500-year period (1470-1991) are studied. It is also analysed the simultaneous possibility of spatial meeting of basin-wide flood event in mainly river basin units in China.
