In this paper, the erosional characteristics along the suizhong sarldy coast of the liaodong bay are analyzed by comparing nautical charts in different periods and analyzing remote sensing images and multi - year field monitoring data, and it is shown from the analysis results that the loose coastal sediments and intense coastal dynamic actions are the basic conditions for the recent coastal erosion, and the decrease in terrigenous material discharged into the sea, marine dynamic actions, coastal engineering structures and offshore sand recovery are the main affecting factors for the coastal retrogradation
摘要通過不同時期海圖對比、分析遙感圖像和多年現場監測資料，分析了遼東灣綏中沙質海岸侵蝕的特點，認為海岸組成物質鬆散與海岸動力作用強烈是本區現代海岸侵蝕的基本條件；陸源物質入海量減少、海動力作用、沿岸工程建築和海上采砂是其海岸蝕退的主要影響因素。 -
The palaeogeographic research indicate that the palaeogeographic outline of the study area recorded the evolution from a sedimentary basin in which the shallow - water carbonate platform sediments and deep - water terrigenous clastic submarine fan developed from southeast to northwest and northeast during the late triassic through a submarine sheet - like model composed of deep - water sandy turbidite and fine - grained turbidite during the early jurassic to a terrigenous clastic barrier coast during the middle and late jurassic and finally to the coal - bearing delta sediments during the late cretaceous
古地理分析表明，研究區晚三疊世古地理輪廓是一個從東南向西北和東北方向由淺水碳酸鹽臺地及深水陸層海底扇沉積共同發育的沉積盆地；早中侏羅世，演變成為一個由深水砂質濁積巖和細屑濁積巖組成的水下席狀體沉積；進入中晚侏羅世，其古地理表現為一個陸屑淺海有障壁海岸；到了晚白堊世，研究區表現為以含煤沉積為特徵的三角洲相沉積。
