| 摘 要： | 选择黄河流域8个水文站点,采用mann-kendall方法,研究其1951-1998年的变化趋势,并确定突变点及其起始位置.结果表明:这些站点存在相同的趋势.年天然径流量除了兰州、河口镇和龙门外,都有显著的下降趋势,突变点在90年代的早期或中期,但是下降的趋势点不同.研究发现,降水存在类似的趋势,是径流量减少的主要原因.同时,人类活动也是径流量减少的重要原因.发展节水灌溉和实施南水北调是缓解水资源短缺的重要途径,但水资源供需矛盾在短期内依然存在.

| Abstract: | Series of annual natural runoff recorded at 8 hydrological stations in the Yellow River basin(YRB),distributed at the main channel and the two most sub-basin,i.e.Weihe basin and Fenhe basin,from 1951 to 1998,are studied.The trends and their beginning points(or abrupt changes) of these series are detected with mann-kendall test(M-K test) and its progressive application according to Sneyers and Goossens.The results show that there are similar trends for different stations.The annual natural runoff series for ... |
