| 摘 要： | 利用杭州、宁波、金华、温州4站近500余年(1470～1990)来的旱涝等级序列及实测降水资料,分析了浙江省近500年来干湿状况变化的若干特征.浙江省干湿状况的长期变化是以干湿期交替出现为特征的,有明显的阶段性和准周期性,没有趋于某一极端的趋势.近500年来,干湿变化与冷暖变化之间的联系以冷干、暖湿形式为主.此外,还指出浙江省干湿状况的变化与太阳黑子磁周期活动有较密切的关系.

| Abstract: | Based on the rainfall data set and the sequences of grades of dryness/wetness in the last 521-year period
(1470-1990)for the four stations in the province of Zhejiang,some features of the evolution of drought and
flood phases are investigated. It is a basic feature that drought and flood phases succeed each other. And the
evolution of drought and flood phases are quasi-periodic. No trend to extremes has been detected. Drought
phase often coincides with cold phase and flood phase with warm phase. Moreover,it is directed that the evo-
lution of drought and flood has a bearing on the magnetic cycle of sunspot. |
