21世纪以来,海滩养护技术开始在我国得到应用并迅速发展。本研究基于对过去十几年来我国海滩养护技术的跟踪与深度研究,通过研读文献、资料收集和数据统计,分析了我国海滩养护发展现状及特征,总结归纳了我国在海滩养护技术方面的创新,最后展望了海滩养护的未来发展并提出了建议。研究发现,我国的海滩养护工程在2005年之前较少,此后快速持续增加;在3种养护目的中,滨海旅游占绝大多数,达61. 7%;修复海滩类型中,人造海滩和修复受损海滩的比例相当,同质养护和异质养护的占比分别为51. 1%和48. 9%;在养护海滩的平面形态中,岬湾形态的占比最高,达43. 6%。结果表明,我国在海滩修复养护技术中取得了一些创新,主要包括强潮海岸、强侵蚀海岸、淤泥质海岸等多种动力条件下的海滩修复理论和理念,以及海滩城市排水优化设计、海滩生态养护潜堤等技术方法。  相似文献

希腊：文明的兴衰之地     

蔡天新 《地图》2009,(1):142-143

地中海几乎是一个内海,适宜于古代商船的航行,加上温暖的天气,这·才产生了欧洲历史上第一个伟大的文明——希腊文明,由此引发了“古典的地中海”的昌盛。后来,这一文明（在克服了微寒的气候以后）又延伸到了“北方的地中海”,即波罗的海、北海和拉什芒海峡（英吉利海峡）,并且在十九世纪末二十世纪初随着航海技术的改进进一步发展成为了“大西洋文明”。而在东方,在中国海的右侧,在日本和台湾、菲律宾之间的海面上,  相似文献   

Cold event at 5 500 a BP recorded in mud sediments on the inner shelf of the East China Sea   总被引：2，自引：0，他引：2  

徐方建  李安春  胥可辉  李铁刚  陈世悦  万世明  刘建国 《中国海洋湖沼学报》2009,27(4):975-984

A 700-year record (1.0–1.5 a resolution) of the East Asian winter monsoon (EAWM), based on grain-size analysis and AMS¹⁴C dating of Core EC2005 from the inner-shelf mud wedge of the East China Sea (ECS), was compared with the Dongge stalagmite δ¹⁸O record during the mid-Holocene. The upper muddy section of Core EC2005 has been formed mainly by suspended sediments derived from the Changjiang (Yangtze) River mouth since 7.3 ka BP. High precipitation and a strengthened EAWM might have played key roles in the high sedimentation rate (1 324–1 986 cm/ka) between 5.9–5.2 ka BP. The EAWM strengthened when the Asian summer monsoon weakened, especially around 5 500 a BP, which corresponded to a worldwide cold event. The EAWM during the mid-Holocene shows statistically significant solar periodicities at 62 and 11 a. The 5 500 a BP cold event might be resulted from orbital forcing and changes in solar activity.  相似文献   

Seasonal variation of the barrier layer in the PN section     

张媛  吴德星  林霄沛  山峰 《中国海洋湖沼学报》2009,27(2):192-201

In this paper, we use the conductivity-temperature-depth (CTD) observation data and a three-dimensional ocean model in a seasonally-varying forcing field to study the barrier layer (BL) in the PN section in the East China Sea (ECS). The BL can be found along the PN section with obviously seasonal variability. In winter, spring and autumn, the BL occurs around the slope where the cold shelf water meets with the warm Kuroshio water. In summer, the BL can also be found in the shelf area near salinity front of the Changjiang (Yangtze) River Dilution Water (YRDW). Seasonal variations of BL in the PN section are caused by local hydrological characteristics and seasonal variations of atmospheric forcing. Strong vertical convection caused by sea surface cooling thickens the BL in winter and spring in the slope area. Due to the large discharge of Changjiang River in summer, the BL occurs extensively in the shelf region where the fresh YRDW and the salty bottom water meet and form a strong halocline above the seasonal thermocline. The formation mechanism of BL in the PN section can be explained by the vertical shear of different water masses, which is called the advection mechanism. The interannual variation of BL in summer is greatly affected by the YRDW. In the larger YRDW year (such as 1998), a shallow but much thicker BL existed on the shelf area.

Analysis of the high and low temperature centers and their relation with circulations in the East China Sea     

YANG Yongzeng  QIAO Fangli  XIA Changshui  GE Renfeng 《海洋学报(英文版)》2009,28(2):14-22

Three warm currents, the Kuroshio, its shelf intrusion branch in the northeast of Taiwan and the Taiwan Warm Current (hereafter TWC), dominate the circulation pattern in the East China Sea (hereafter ECS). Their origination, routes and variation in winter and summer are studied. Their relationship with four major high and low temperature centers is analyzed. Differing from the previous opinion, we suggest that the four major centers are generated to a great extent by the interaction of the currents in the ECS. In summer, a cold water belt in the northeast of Taiwan is preserved from winter between the Kuroshio and the TWC. The shelf intrusion branch of the Kuroshio separates the water belt, and two low temperature centers generate in the northeast of Taiwan. In the southern ECS, the TWC transports more heat flux northward to form a warm pool. But it is separated in the lower layer by the cold water driven by the intrusion branch of the Kuroshio. So the TWC and the intrusion branch of the Kuroshio play a dominating role to generate the high temperature center. The interaction among the eastward TWC, the northward Tsushima Warm Current (hereafter TSWC) and the southward Su Bei Coastal Flow (hereafter SBCF) generates the low temperature center in the northern ECS. In winter, the strengthening of the shelf intrusion branch of the Kuroshio obscures the two low temperature centers in the northeast of Taiwan. For the weakening of the TWC, the high temperature center in the southern ECS vanishes, and the low temperature center in the northern ECS shifts to south.  相似文献
