摘　　要：内陆水下及近岸地形数据获取有助于对内陆水域进行综合开发和精细化管理,具有重要的社会、经济和生态意义。针对单一数据获取难以满足复杂地形测量的问题,本文提出一种多源数据获取方法,采用航空摄影、机载激光雷达、多波束和单波束测深系统、人工实测等方法获取多源数据,经数据处理后获取全面覆盖水下、近岸、水陆交接处的地形数据,并以尼山水库为例进行试验应用。结果表明,本文方法既实现了水上水下一体化地形数据的获取,又保证了测量成果精度的可靠性,可广泛应用于大中型水库测量工程,为内陆水下及近岸地形测量提供技术支撑。The acquisition of inland underwater and nearshore topographic data is helpful for comprehensive development and refined management of inland waters,and has important social,economic and ecological significance.Aiming at the problem that a single data acquisition is difficult to meet the complex terrain measurement,this paper proposes a multi-source data acquisition method,which adopts aerial photography,airborne LiDAR,multi-beam and single-beam bathymetry system,artificial measurement and other methods to acquire multi-source data.Data processing obtains terrain data that comprehensively covers underwater,near-shore,and land-water junctions.This paper takes Nishan reservoir as an example for experimental application.The results show that the method in this paper not only realizes the acquisition of integrated topographic data on water and underwater,but also ensures the reliability of the accuracy of the measurement results.If can be widely used in large and medium-sized reservoir survey project to provide technical support for inland underwater and nearshore topographic survey.
