基于机载LIDAR技术的海岸带防风暴潮能力评估
|
摘要
机载LiDAR技术具备快速、精确获取地面高程信息的特点,在海岸带风暴潮灾害防御能力评估方面可以发挥重大作用。本文以惠东县盐洲岛为研究区,基于机载LiDAR点云数据和航空影像数据,提取研究区的路堤、海岛高程,土地开发利用等信息,利用DEM模拟风暴潮淹没范围,评估研究区路堤建设情况及其面临风暴潮灾害的防护能力。实验表明:盐洲岛12.54%的路堤缺乏防御风暴潮灾害能力;在水位达到3.5 m、4.4 m、4.6 m时,分别有71.38%、83.17%、84.18%的海岛范围面临遭受风暴潮灾害的风险。
Featuring in getting ground level information with its quickness and accuracy,Airborne LiDAR system play an important part in coastal zone storm tide prevention ability assessment.Extracting information of embankment,island elevation and land development and utilization in the research area based on airborne lidar point cloud data and aerial image data,and simulating storm surge submergence range by DEM are accomplished to evaluate the embankment construction and its anti-storm surge capacity in the research area.It shows that 12.54% of the embankment in Yanzhou Island is lack of storm tide prevention ability; 71.38%、83.17%、84.18% of the island is at risk of storm tide accordingly at the water level of 3.5 m、4.4 m、4.6 m.
