| 摘 要： | 以珠江上游流域为例,采用线性回归分析、Mann-Kendall检验、小波分析等方法分析了1959～2008年枯水期降水时间系列。结果表明,近50年来,珠江上游流域枯水期降水呈不显著变化趋势(增加率1.0mm/10a),枯水期降水存在约2、6、13、30年的主周期,其中以13、30年周期变化最为显著。

| Abstract: | Taking the upstream of Pearl River Basin for an example,this paper analyzes precipitation time series in low water season during 1959～2008 by using linear regression,Mann-Kendall test and wavelet analysis method.The results show that in recent 50 years,precipitation in low water season presents an insignificantly increasing trend with a rate of 1.0 mm per 10a;as can be seen from period,the low water season precipitation appears 2,6,13 and 30 year periods,of which the most significant variation occurred in 13 and 30 years. |
