莱州湾东岸动力地貌对陆海相互作用的响应研究
Dynamic geomorphological response to land-sea interaction on the eastern coast, Laizhou Bay
摘要
Abstract
Based on SRTM3_DEM and RS analyses, field survey data and previous studies, this study examines the geomorphic features and landform growth of the coastal alluvial marine plain on the east coast of Laizhou Bay. The results show that the geomorphologic structure of the coast occurs as a barrier-lagoon system in the transverse di-rection and a tombolo-lagoon system in the longitudinal direction. Systematic bending characteristics occur in the downstream channels of the rivers as they enter the sea, which correspond with the barrier-lagoon system. This is the most significant sign of fluvial geomorphological response to coastal land-ocean interaction since the mid-Holocene. Hydrologic analysis of the DEM shows that the terrain inclines in two directions, from east to west and south to north, and the watershed extraction from the Wanghe river corresponds to the watershed extraction downstream of the Wanghe paleochannel from east to west. This results in the expression of the current channel and paleochannel manifesting by different threshold values.关键词
