摘　　要：针对山区河流流经区域地理条件复杂、导致航道整治控制测量难度大等问题,结合沱江自贡段航道整治控制测量的实施情况,分析控制点布设、坐标系统选择以及平面和高程控制测量方法的选用。根据山区航道的特征,提出最优的平面坐标系统布测方法。研究成果可为后续山区长河道航道整治控制测量提供参考和借鉴,推动山区长航道整治工作的顺利开展。Aiming at the complex geographical conditions of the mountainous rivers flowing through the region,which leads to the difficulty of the control measurement of waterway improvement,combined with the implementation of the control measurement of waterway improvement in Zigong section of Tuo River,the layout of control points analysis,selection of coordinate systems,and selection of methods for plane and elevation control measurement were conducted.Based on the characteristics of mountainous waterways,the optimal method for layout and measurement of plane coordinate systems is proposed.The research results can provide important references and inspirations for the subsequent control measurement of long river channel regulation in mountainous areas,which will promote the smooth implementation of long river channel regulation in mountainous areas.
