摘要
三道营水文站地处密云水库上游,为海河流域潮白沙水系黑河控制站,集水面积1600km2,结冰期从当年11月至次年3月,约占全年时间2/5,冰期径流量占多年平均径流量的1/4。文章通过对多年实测资料的分析,掌握黑河三道营水文站河道冬季的结冰过程和次年春天消冰开河过程,并就河道结冰的变化过程对于水位流量的变化规律进行了初探。
The Sandaoying hydrological station is located on the upstream of the Miyun reservoir, being the control station of Heihe river belonging to Chaobai fiver water system in the Haihe river basin with the water-collection area of 1600km2, the ice period is from November to March next year, accounting for 2/5 of the year and 1/4 of the mean annual runoff. By analyzing the over-year data observed, the paper grasped ice freezing process in the river course of Saodaoying hydrological station in winter and the ice break-up process, and explored primarily the stage-discharge changing law due to the changing process of ice-freezing in river course.
