摘要
Abstract
GPS-RTK technology was used to measure the underwater topography of three islands of Jinshan district in 2016.Underwater topography cloud chart was drawn and compared with the results of underwater topographic survey in 2014 and 2015.The results showed that the terrain has big change in the line within a kilometer of three islands.There is a pit in the north and south side of Small Jinshan Island and an EW direction deep trough between the Big and Small Island, whose formation is inconsistent with the ebb and flow and human activities.The terrain between Big Island and Fushan Island is like a mountain ridge.There is also a pit located in the south of Fushan Island.In the past three years,the underwater topography of three islands of Jinshan dis-trict has changed little,and there are deposition and erosion in partial small area.Measuring the underwater topography of three islands of Jinshan district regularly can help master the law of change,and provide basic information for management.关键词
