摘要
通过对1919~1977年黄河中上游玛多、兰州、西宁、延安、太原、西安、郑州等16站的旱涝等级和,陕西黄帝陵园柏、华山西峰顶华山松、河南孟津侧柏、黄河上游阿尼玛卿山园柏树木的年轮,以及通天河直门达站年径流量诸因素与花园口站汛期天然径流量的相关分析,建立了花园口站径流量回归模型,重建了1485~2007年的天然径流量序列,并就其历史变化特点进行了分析。结果表明:①重建序列与现有序列具有较好一致性;②近523年径流量变化具有较明显的阶段性,大致经历了9个枯水段和8个丰水段。
By the correlation analysis between the summation of dry and flood degree of Maduo, Lanzhou, Xining, Yan'an, Taiyuan, Xi'an, and Zhengzhou, the tree rings of the savine at Huangdiling in Shaanxi, the Huashan pine at the west peak in Huashan, Mountain the oriental arborvitae in Mengjin county in Henan, and the savine in Mount Animaqing in Yellow River upper reach; the yearly runoff at Zhimenda Station in Tongtianhe River, and the natural runoff at Huayuankou Station in flood season from 1919 to 1977, we established the natural runoff formula of Huayuankou Station in flood season, and rebuilt the series of natural runoff from 1485 to 2007. Afterwards, we analyzed the stages and periodicity of runoff. Results showed that:(1)the reconstruction sequence of runoff were very uniform with the current one; (2) the runoff in the past 523 years took on obvious phased changes, which approximately came through 9 low-flow periods and 8 ample-flow periods.
