摘要
本文利用《中国五百年旱涝等级图》资料,用W-K模糊沉底聚类法对我国进行旱涝区域划分,共得到8个旱涝区域。在此基础上,分别研究了旱涝周期和干、湿期划分以及一些总体变化特征。
By use of china's drought/flood grade atlas for the past 500 years (covering 100 stations) and the WK sinking fuzzy clustering method,areas of drought/flood in China are classified into eight main types.On this basis, studies are carried out on the drought/flood cycle andtrend, the classification of dry/wet Periods, and some statistical features.
