近年来,随着白石水库流域各项综合治理工程的修建,河道受到了更多人为因素干扰,水沙条件发生极大改变。新的水沙条件使大凌河中下游河段产生了新的演变趋势。本文以白石水库流域上窝堡(大城子)、朝阳、义县、凌海4座水文测站实测水沙数据为基础,分析研究白石水库流域近期来水来沙特性,以及水沙在时间和空间上的趋势走向,为大凌河保护区流域日后的综合治理提供决策依据。
In recent years, with the construction of various comprehensive treatment projects of the Baishi Reservoir Basin, the river has been disturbed by more human factors, and the water and sediment conditions have greatly changed. The new water and sediment conditions have led to a new trend of evolution in the middle and lower reaches of the Daling River. Based on the measured data of water and sediment at four hydrological stations in Shangbaibu (Dachengzi), Chaoyang, Yixian and Linghai in the Baishi reservoir basin, the characteristics of recent incoming and outgoing water and sediment in the Baishi reservoir are analyzed, Spatial trend of the direction for the Daling River Basin in the future to provide a comprehensive management decision-making basis.
