摘　　要：在对沿海虾蟹养殖坑塘进行回收时需进行坑塘回填,一般通过水下测量获取,获得坑塘水底的水深值。人工划船辅以RTK的传统测量方法效率低且人工投入大、单波束测深仪又存在覆盖范围窄和测量精度低的缺点,无法满足短平快的日常测绘要求。多波束测深技术的不断发展和成熟给水下测量方法提升带来可能。经分析,使用多波束测深仪在坑塘等超浅水域测量中有明显效果,因其具有测量范围大、测量速度快、测量精度和效率高的优点,特别适合进行大面积的水下探测。并与传统方法的测量精度进行比较,得出多波束测深仪在超浅水域中的测量可满足日常沿海虾蟹养殖坑塘的测绘要求。When recovering the coastal shrimp and crab breeding pits,it is necessary to backfill the pits,which are generally obtained through underwater measurements to obtain the water depth value of the bottom of the pits.The traditional measurement method of manual rowing supplemented by RTK has low efficiency and large personnel investment,and the single-beam sounder has the disadvantages of narrow coverage and low measurement accuracy,which cannot meet the requirements of short,flat and fast daily surveying and mapping.The continuous development and maturity of multi-beam sounding technology has brought the possibility of improving underwater measurement methods,and after analysis,the use of multi-beam sounder has obvious effects in the measurement of ultra-shallow waters such as pit ponds,because it has the advantages of large measurement range,fast measurement speed,high accuracy and high efficiency,and is especially suitable for large-area underwater exploration.Compared with the measurement accuracy of the traditional method,it is concluded that the measurement of multi-beam sounder in ultra-shallow waters can meet the daily surveying and mapping requirements of coastal shrimp and crab breeding pits.
