中文摘要:
      采用侧扫声纳系统,对大连市金州湾蚂蚁岛海域中A、B两个石料人工鱼礁区进行调查评估,将声学方法应用到石料礁堆体积估算中,目的是探究石料礁堆体积估算的新方法,提高计算结果的准确性,进而提高工作效率。使用侧扫声纳系统进行数据采集,通过相关数据处理软件和计算机辅助技术对声纳数据进行后处理,提取石料礁堆特征图像,结合函数曲线对石料礁堆体积进行估算。结果显示,侧扫声纳图像能够清晰反映石料礁在海底的分布状态,根据图像能够对石料礁的冲淤程度进行判别,利用几何关系及相关技术手段对石料礁堆体积进行估算,估算结果存在一定误差,通过多次不同角度的检测或配合其他辅助软件能尽可能减小误差。在A石料礁区,运用积分断面法估算的石料礁堆体积与该礁区投放纪录的实际体积相比,相对误差接近16%;对B石料礁区进行检测评估,所得石料礁堆体积与实际体积之间的相对误差也接近16%。两个石料人工鱼礁区所估算的体积与实际体积相差均很少,虽然两个礁区物理环境以及石料礁堆大小均不同,但二者相对误差接近且均小于20%,验证了积分曲线的合理性。因此,在诸多不确定因素的影响下,该方法可相对精确地估算石料礁堆体积,可为人工鱼礁区建设、管理和评价提供支持和依据。
英文摘要:
      In this study, we used the side scan sonar system to investigate and evaluate the two artificial stone reef areas in A and B in the sea area of the Mayi Island in Jinzhou Bay, Dalian. The acoustic method was applied to the estimation of stone reef volume. The purpose was to explore the new estimation method of stone reef volume to improve the accuracy of the calculation results, improve work efficiency. The data mining of the sonar data was carried out by using the data processing software and the computer-aided technology. The data of the stone reef were extracted and the volume of the stone reef was estimated by the function curve. The results show that the side scan sonar image can clearly reflect the distribution of stone reefs in the seabed, and the scouring and silting degree of the stone reef can be judged according to the image. The geometric relationship and the related technical means are used to estimate the volume of the stone reef. Through several different angles of detection or with other auxiliary software errors were minimized. In the A reef area, the volume of the reef is estimated by the integral section method and the relative error is close to 16% compared with the actual volume of the reef area. The B reef area is tested and evaluated. The relative error between the evaluated volume and actual volume of the stone reff is close to 16%. The estimated volume of the two artificial fish reef areas is very different from the actual volume. Although the physical environment and the size of the reefs are different in the two reef areas, the relative error is close to and less than 20%. The integral curve is verified rationality. Therefore, under the influence of many uncertain factors, this method can estimate the volume of stone reefs relatively accurately, which can provide support and basis for the construction, management and evaluation of artificial reef area.
