| 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。

| Abstract: | The yearly and seasonal flood and drought status in Rizhao were analyzed based on precipitation anomalous percentage and Z-index.The results show that precipitation anomalous percentage reflect the flood or drought degree more lighter,and Z-index can be 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 1960s and 1970s it was a flood period and in the 1980s and 1990s it was a drought period in Rizhao,and generally the drought even... |
