摘要

摘要: 根据嫩江主要代表水文站石灰窑、同盟、江桥、大赉1956-2006年51年的径流资料,应用数理统计、累积滤波器、Mann-Kendall秩相关法及小波分析法等多种方法,分析了嫩江径流年内、年际变化特征及其影响因素。结果表明:嫩江径流年内分配不均匀,主要集中在7、8、9月份。嫩江年径流量在1963年左右发生了一次全流域的减少突变,80年代径流有所增加,90年代中后期又发生了一次减少突变。嫩江径流主要存在8年的年际周期,20年及大于40年的年代际周期。径流变化的主要气候影响因素是降水,人类活动通过土地覆被变化及水利工程等对径流也有重大影响。

Abstract: Based on the runoff data of Nenjiang River in 1956-2006,the Mann-Kendall,the wavelet wave analysis and the cumulative filter methods are used to find out the variation law and its impacting factor of runoff amount in Nenjiang River.The result shows that the runoff annual distribution in Nenjiang River is not uniform and occurs mainly in July,August and September.The result also shows that the runoff amount decreases in the recent 50 years,and more significant in the early of 1960s, while in the 1980s there is a trend of increase,but it isn't significant.In the middle and late of 1990s the runoff amount decreases again.The runoff changes from year to year with a change periodicity of 8 years.And other change periodicities are of 20 years and 40 years or longer.The most important climate factor is precipitation and evaporation.The human activity is also an important factor.
