| 为研究西沙宣德环礁海底地貌特征及珊瑚分布情况，采用舷挂侧扫拖鱼的方式对环礁区域海底进行地貌扫测，从采集的侧扫声呐图像上可以识别出环礁区域珊瑚分布情况及珊瑚礁区地貌特征，利用侧扫声呐图像识别方法结合实物样品比对可以圈定出珊瑚分布范围、暗礁区域及环礁区域底质类型分布，采用基本的数学处理方法定量分析了水下珊瑚礁体的海底高度及疑似沉船的大小，分析了侧扫声呐图像显示的调查船转向效应。 |
| 英文摘要: |
| To study the seabed topography characteristics and coral distribution of Amphitrite Islands in Xisha Islands, the geomorphological survey was carried out on the seabed of the atoll region by means of sweeping and towing fish on the side of the gunwale. The distribution of coral in the atoll area and the geomorphological features of the coral reef area can be identified from the acquired side scan sonar images. By using the side-scan sonar image recognition method and comparing with real samples, the distribution range of corals, the distribution types of bottom materials in reef areas and atoll areas can be delineated. The submarine height of the underwater coral reef and the size of the suspected sunken ship were quantitatively analyzed by using basic mathematical processing methods, and the steering effect of the survey ship displayed by the side-scan sonar image was studied. |
