Based on a cooperative study between China and France on tidal deposits in theEastem Bohai Sea in 1991, intermlationships between water depth, sediments, bedforms and tidalcurrents on China's continental shelves were analysed.

Based on a cooperative study between China and France on tidal deposits in theEastem Bohai Sea in 1991, intermlationships between water depth, sediments, bedforms and tidalcurrents on China's continental shelves were analysed. The results tha tidal currents play a majorrole in the creation of the present submarine geomorphology and depositional processes on China'sshelves. If the tidal-current velocity exceeds 3 knots, then erosional action dominates and rectilinearcurmnts form mostly deep scour furrows. When the tidal-current velocity ranges between 1 and 3knots, deposition is dominant and tidal currents form tidal shoals, i. e., tidal sand ridges and tidalsand sheets. The boundary between the ridges and the sheets lies near the location where theabsolute value of the M2 ellipticity is 0.4. Where the absolute value is less than 0.4, tidal sandridges are often formed in response to rectilinear currnts. Where the absolute value exceeds 0.4,tidal sand sheets tend to be formed in response to rotatory currents. There are five modemhda-deposihonal systems on Chinas continental shelves and the surrounding areas: (1) the tidaldeposit over the eastern Yellow Sea (composed of tidal sand ridges in West Korea Bay and tidalsand sheets off South Korea), (2)the tidal deposits over the eastern Bohai Sea (composed of tidalscour furrws in the Laotieshan Channel, tidal sand ridges in the Liaodong Shoal and tidal sandsheets on the Bozhong Shoal); (3)the tidal depositional system of f the Changjiang River estuary(composed of tidal sand ridges off the Jiangsu Province and tidal sand sheets on the Yangtse Shoal),(4)the deposits distributed to the west of Taiwan Island (composed of tidal scour furrows in theTaiwan Strait, tidal sand ridges over the Taiwan Shoal, tidal scour furrws in the Penghu Channeland tidal sand sheet on the Taizhong Shoal), and (5) the depositional system in the Qongzhou Strait(composed of hdal scour furrows in the Qongzhou Strait tidal sand ridges on the eastem andwestern shoals). In addition, there are moribund tidal deposits in the East China Sea which formedduring an eary stage of the last transgression. The Holocene tidal-deposits on China′s continentalshelves can be divided into a strait-shoal type and an ordinary shoal type.

在1991年中法合作渤海潮流沉积研究的基础上,查阅了国内外有关研究成果,分析了中国陆架的水深地形、沉积地貌与潮流动力的关系,认为潮流对中国陆架的海底地貌和沉积的形成发育起了主导作用。当潮流流速大于3节时,潮流的侵蚀作用是主要的,往复潮流多形成冲刷深槽,大大刷深了海峡或水道。当潮流流速1-3节时,潮流的沉积作用是主要的,多形成浅滩,即潮流沙脊和潮流沙席。以M2分潮椭率绝对值0.4为界,大于0.久者意味着潮流旋转性强,多形成潮流沙席;小于0.4者意味着潮流往复性强,多形成潮流沙脊。提出了我国邻近陆架发育了5个现代潮流沉积地貌体系:(1)黄海东部潮流沉积体系,它由西朝鲜湾潮流沙脊和其南部的沙席两者组成;(2)渤海东部潮流沉积体系,它由老铁山水道冲刷槽,辽东浅滩沙脊和渤中浅滩沙席三者组成;(3)长江口外潮流沉积体系,它由江苏滨外潮流沙脊和长江口浅滩潮流沙席组成;(4)台湾滨外潮流沉积体系,它由台湾海峡冲刷槽、台湾浅滩沙脊、澎湖水道冲刷槽和台中浅滩沙席四者组成;(5)琼州海峡潮流沉积体系,它由琼州海峡冲刷槽、东浅滩沙脊和西浅滩沙脊三者组成。此外,在东海陆架上还有冰后期海侵早期形成的残留潮流沉积体系。全新世陆...

The HUanhe River discharged into the southem Yellow Sea through the Huanghe River estuary from 1128 to 1855 A. D, which resulted in flooding and waterlogging in the midddle and lower Huaihe River basin. on the othr hand, the modem channl of the lower Huanhe River is often taken as an analogy with the old Huanghe River. Therefore, in order to provide a theoretical foundation for appropriate hamssing Plans of both the Huanghe and Huaihe Rivers, it is neccessary to study the geomorphic evolution in the lower Huaihe mver basin. Howevef, except for the coasdine evolution of the old Huanghe mver delta since 1128 A. U, no ahention has been paid to the estuarine morphodynanic evolution of the Huanghe River estuary during 1128 to 1855 A. D.Based on historical liteares, this paper has discussed the dyAnc processes, geomorphology of the Huaihe River estuary during thes period of hme. Compared with the conteInporary Huanhe River,the Huaihe River estuary has a lareer runoff and silt dischnye which, was effected by the downfilling which took place in the lower Huanghe River valley for several times. The Huaihe estuary is a meso-tidal estuary with an average tide ranqe of over 3.2m. The tidal current and coastal current help silt diffuse into the Yellow Sea rapidy- The Huaihe River estuary is funnel-shaped with two crossing spits, a large bay mouth sand bar and submrged delta- The channl of the esmp has an obvious meandr form. The width of the mouth has a bend of increasing since 1700 A. n. During 1128-1855 A. D the hdal cimnt lindt ndgatd along the river continuously, and the estuary sbetohes toward the sea at the same hme. Because the tidal current lindt has a ndgrating disate much larges than the sbetohing disate of the mouth pasition, the length of the estuary channl below the tidal current limit becoms piogressively shoher. In response tO the energy dissipation and the reduchon the longitudinal gndent the estuarine channl developed a dishnchy meandring patterm- Thus, the Huanghe and the old Huaihe hivers have estuaries with different types, and there is no estuarine dynaxnorohic basis for the analogy between them.

根据历史文献资料,对黄河在淮期间淮河入海河口的动力条件、地貌特征及其演变机制进行了研究。结果表明,历史时期因大量多泥沙黄河径流汇入,淮河河口径流量、输沙量增大,但不同时期输沙量又受黄河下游反复进行的沿程淤积的影响而有变化。淮河口是中等强度的潮汐河口,其往复潮流和沿岸流系统非常有利于入海泥沙扩散。淮河口呈上窄下宽的喇叭口形,口门内、外侧分别发育有大规模拦门沙及水下三角洲,河口段河道具有典型的弯曲河型,自18世纪以后口门宽度有增大的趋势。淮河口演变的机制是潮流界不断向下游迁移、河口不断向海延伸,而且潮流界下移距离远大于同期河口外延距离,河口段长度急剧缩短。为了适应径流、潮流消能的需要,河口段河型向曲流化发展、口门展宽。古淮河人海河口和现代黄河河口具有不同的动力地貌特性和演变机制,其间不能作简单类比。
