摘要
进入洞庭湖的洪峰流量超过40000m ̄3/s时,称为大洪水年;城陵机水位达33.0m(冻结)以上时,本文中称为大洪灾年.将两个序列按大小顺序排列后发现,除第1及第5位分别同是1954年和1969年外,其余均不对应.本文对产生该现象的原因进行了系统分析.并在洪峰影响因素与最高洪水位间进行回归分析,得出经验方程式.
The time when the flood flow of Dongting Lake is over 40000m ̄3/s is called thegreat flood water year and when the water stage at Chenglinji is over 33.0m (freezing) iscalled the great flood disaster year. After arranging these two series in accordance with sizeorder, it is discovered that with the exception of all the 1st and 5th places being respectively1954 and 1969 in these two series, all the rest places are not correspondent. The causes ofproducing this phenomenon are systematically analyzed in this paper. Analysis is also madebetween the causes influenced by flood peak and the highest flood stage. Finally, the relatedexperiential equation is obtained.
