浮渡河河口滨海沉积地貌的三维地形测量研究

Research on Three-Dimensional Terrain Survey of Fudu River Coast Estuary's Sedimentary Geomorphology

浮渡河是大连与营口的界河,由于海洋水文动力作用和陆域河流输沙,该地区滨海沉积地貌发育,广泛分布沙坝、沙嘴及瀉湖沉积。文章利用RTK GPS对该海域进行了地形测量及地貌调查,并利用计算模拟重现调查时段的三维沉积地貌,分析和研究了形成的地貌类型和尺度,探究该海洋地貌类型可能的形成机理。通过上述研究,为该浮渡河口沙堤自然保护区和沙嘴海洋特别保护区的海洋生态保护与管理提供科学依据。

Fudu river is boundary river between Dalian and Yingkou, coastal sediment of the area was eveloped very well,Sandbank,Sand mouth and Lagoon deposition are distributed widely due to effect of marine hydrological dynamics and land river sediment transport.This paper surveyed topography of this area by RTK GPS,and 3D sedimentary features of Survey period was reappeared by computational simulation,geomorphological type and scale's formation were analyzed and studied,possible formation mechanism of this marine geomorphological type was explored.Through the above analysis, to provide scientific basis for the marine ecological protection and management of Fudu river's nature reserve and sand mouth marine special reserves.
