摘　　要：根据晋江流域安溪和石砻水文站历年径流量序列和降水序列,应用了Mann-Kendall法、集中度和集中期Morlet小波等数学方法,对该流域径流的演变规律进行了分析,研究结果表明:径流年内分配极不均匀,全年径流主要集中在5、6、7、8、9月份,占全年径流量的60%以上,冬季径流量很小,占全年平均径流量的比例不足10%;从径流年内分配的集中性来看,安溪水文站的径流年内分配集中度20世纪60年代最大为49%,其余年代均较小;从变化趋势来看,晋江上游安溪站年均径流量较稳定,基本无变化,晋江下游的石砻站年均径流量趋势变化较上游强烈,具体表现为50年代未至70年代初表现出下降趋势,90年代至今表现为上升趋势。但晋江流域水文站的年均径流量在过去的53年中均没有明显的上升或是下降趋势。According to previous runoff volume and rainfall of Anxi and Shilong hydrometric station in Jinjiang River basin, the evolvement rule of runoff volume was analyzed by using Mann - Kendall, concentration degree, concentration period and Morlet wavelet methods. The results showed that ： The runoff distribution of the Jinjiang River in a year is very uneven, more than 60% of runoff volume mainly focus on May, June, July, August and September,winter＇s runoff volume is very little, less than 10% ; Anxi hydrometric station＇s runoff mainly focus on 1960s＇ according to interannual distribution of runoff contration degree, occupy 49% , the rest time are all relatively little; Anxi hydrometric station＇ s runoff according to the change trend has no significant changes, Shilong hydrometric station＇ s runoff change is more obvious than Anxi. In more specific terms, in the late 1950s＇ to early 1970s＇ is decline, 1990s＇ to now is increase trend, but the average annual runoff has no decline or increase trend in the last 53 years.
