摘要:

 对山东省日照市年和各季节的旱涝情况使用降水距平百分率指标和Z指数旱涝指标2种方法进行了应用对比分析。结果表明:Z指数旱涝指标能较客观地反映旱涝程度,降水距平百分率指标反映旱涝程度较轻。在此基础上,用Z指数指标对日照市1955年以来的旱涝进行了逐年分析,发现日照市年和各季节旱涝变化都具有鲜明的阶段性及群发性特征,总体上旱情重于洪涝。

关键词: 旱涝指标, 降水距平百分率, Z指数

Abstract:

The yearly and seasonal flood and drought status in Rizhao were analyzed based on p recip itation anomalous percentage and Z- index. The results show that p recip itation anomalous percentage reflect the flood or drought degree more lighter, and Z - index canbe more accurate. In this paper the Z - index was used to analyze the flood and drought status from 1955 to 2005 and found that in the 1960 s and 1970 s itwas a flood period and in the 1980 s and 1990 s itwas a drought period in Rizhao, and generally the drought events occuerred more frequently than the flood..

Key words: flood and drought index, p recip itation anomalous percentage, Z - index
