滦河发源于内蒙古高原,中游穿过燕山山地,经滦县大桥向南流入平原,在乐亭县王庄子公社汇入渤海。历史时期,滦河口多次分流改道,先后形成了全新世早期、全新世中期、历史早期、历史晚期和最新的五个次一级的三角洲体,从而构成了滦河复式三角洲体。滦河的径流量和输沙量呈明显的季节变化。夏季洪水期以径流作用为主,表现为三角洲堆积向前延伸,枯水季节以波浪作用为主,表现为三角洲前缘被破坏和改造。关于滦河三角洲,在国内不少单位已进行了较多的研究工作,并取得了较丰硕的科研成果。但对某些个别问题的解释尚存有争议。本文对现代滦河口及其周围海
Luanhe originated in the Inner Mongolia Plateau, the middle reaches through the Yanshan Mountains, south of the Luanxian Bridge into the plain, in Laoting County Wangzhuangzi commune into the Bohai Sea. During the historical period, the Luanhe River diversion diversions, has formed the early Holocene, mid-Holocene, early history, late history and the latest five sub-level delta body, thus forming the Luanhe duplex delta body. Luanhe runoff and sediment discharge showed a clear seasonal change. The summer flood period is dominated by runoff, which is characterized by the forward extension of the delta accumulation and the wavy season in the dry season, which is characterized by the destruction and alteration of the delta front. On the Luan River Delta, many units in China have carried out more research and have made more fruitful achievements in scientific research. However, the interpretation of some individual issues remains controversial. This article on the modern Luan estuary and its surrounding sea
