摘要
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, the river channel is affected by more human factors, water and sediment conditions are chan.ged greatly with the construetion of various comprehensive treatment projects in Baisht Reserver Basin. New water and sediment conditions lead to new evolution trend on middle and downstream river sections in Daling River. ha the paper, water and sediment data measured in four hydrologic stations on Baishi Reservoir basin are adopted as basis, including Wobao （Dachengzi）, Chaoyang, Yigian and Linghai. Recent coming water and sediment characteristics in Baishi Reservoir basin and trend of water and sediment on time and space are analyzed and studied thereby providing decision-making basis for Subsequent comprehensive governance in river basin of Daling River protection zone.
