青岛地区从近代出土文物考证,早在新石器时代已有人类聚居生活,胶县城南三里河是著名的新石器时代遗址,通过发掘,上层为龙山文化遗址,下层为大汶口文化遗址。即墨县、崂山县也出土过新石器时代的文物。据有关考证资料,青岛地区古属东夷地,周为夷国,春秋时代大部分地区属齐国,胶南沿海一带属鲁国,至今本区境内还残存有齐长城的数段遗迹,黄岛区的于家河村附近抵胶州湾边为齐长城的末端。秦代,本 相似文献

长江三角洲地区全新世以来环境变迁对人类活动的影响 总被引：7，自引：0，他引：7
对长江三角洲地区搜集的泥炭、贝壳砂堤、埋藏古树的测年数据,新石器时代考古遗址点的测年资料以及海拔高程等的分析表明：新石器时代人类的生产和生活与生态环境变迁有密切关系,表现出人类活动对环境变迁的适应。马家浜时期气候潮湿,地面水域扩大,房屋大多以干栏式为主,而且遗址大多分布在山坡和湖汊岸边稍高的岗地、土墩上;崧泽文化期湖泊沼泽比较多,遗址多建于河湖间高爽处;良渚文化时期泥炭埋藏点的分布较马家浜与崧泽文化时期少,而且距离湖泊较远,表明当时地理环境有所好转,适宜人类生活的空间变得更为宽广,遗址的分布开始分散。对古遗址高程以及埋藏古树、泥炭^14C年龄数据统计分析结果表明,新石器时代人类居住高程与地面水域扩张和缩小状况相一致。同时,研究结果也表明影响人们居住地高低的因素较多,先人们的“择高而居”在某种程度上也只是部分地防止海水倒灌及台风和洪水灾害的侵害而采取的一种解决手段,而不是全部,如良渚文化时期部分高遗址点是出于宗教因素。 相似文献

一、历史变迁概况据历史考证,远在新石器时代,黄河直入渤海,按照史籍记载,从公元前132年起,黄河开始南侵淮河流域,直到1855年铜瓦厢决口黄河北徙山东入渤海为止,其历史变迁可分为三个阶段(表1)。 相似文献

我国出土五千年前海产鱼类的分析研究 总被引：2，自引：0，他引：2
在公元前十六世纪商朝殷墟甲骨文中有象形文字“鱼”字的出现,到了春秋战国,管子治齐以“渔盐致富”实为利用海鱼资源一例证。但上溯到新石器时代,我国古代人民如何利用海鱼资源?能捕到哪几种海鱼?由于资料缺乏,迄今还是一个空白。 1974—1975年,中国社会科学院考古研究 相似文献

Archeological evidence of Pacific salmon in Hokkaido is reviewed and compared with results from western North America. Salmon remains have been found at 24 sites in Hokkaido from the Early Jomon Period to the Ainu Period (6000–100 years ago). Fish remains at three archeological sites in the Kushiro River basin indicated that Pacific salmon (Oncorhynchus spp.) were distributed and utilized from 6000 years ago. The present Kushiro Wetland was formerly covered with seawater and called the Paleo Kushiro Bay 5000–6000 years ago. Based on the molluscan fossil fauna, seawater temperature at Paleo Kushiro Bay was about 5°C warmer than at present. Warmer conditions for salmon in Kushiro 5000–6000 years ago corresponded with the poor conditions for salmon in the Columbia River basin 6000–7000 years ago. If the future global warming is similar to the conditions that prevailed 5000–6000 years ago, the southern limit of salmon distribution will shift northwards and the salmon production will decrease. However, they will not disappear from either Hokkaido or southwestern North America. 相似文献

This paper discusses level changes of the sea in the last 6000 years and the recent crustal movements of the coasts of the South China Sea. There was one transgression in the middle Holocene (about 6000-3000 years ago); the sea level might not be higher than the actual one. Many terraces and coral reef platforms above the sea level can be explained by recent crustal movements.As far as the intensity of the crustal movements are concerned, the NE faults are the strongest, the NW next, and the WE are the weakest. They intersect ia block-faulting, differing in seismic activity, crustal movement rate and amplitude. On the whole, they gradually become stronger from west to east in accordance with the increasing tendency of stress field.The land is tilting toward the sea, especially ia western Guangxi Province. 相似文献

全新世以来,世界海面大幅度上升,渤海海区发生了明显的海侵,玉木冰期低海面时期的近海广大陆域皆沉溺于海平面以下。辽东湾由于地质构造复杂及沉积作用速度分布不均匀等因素,海底保存了一部分玉木冰期低海面时期陆地或滨海区的地貌形态及相应的老沉积物的遗迹。它们虽然经过了后期水动力条件及沉积作用的改造,但是,仍不同程度地反映出原始地貌的迹象和某种残留沉积的特征。
关于辽东湾残留地貌和残留沉积的问题,过去曾有报道;本文在以往调査的基础上,结合近期有关资料,对此作进一步的探讨。 相似文献

This paper describes changes in sea level off the coast of China in history and at present. The evidence concerning low sea
level during the last glacial phase, Holocene marine transgression which was discovered from sea bottom in East China Sea
and China's bordering seas, and their adjacent coastal areas, where, by drilling, relic sediment, peat deposite, and mollusc
shell fossils have been obtained, and their dates are deduced through measurement of radiocarbon (C14), identified that low sea level about 15000 years ago stood in the depth of 150 m below the present level in East China Sea,
and that the subsequent transgression carried the sea up to the present sea level 6000 years ago, when the present China's
coast and other continent's coasts were outlined.
Due to a number of factors, the sea level oscillates seasonally in the border sea of China. Averagely speaking, the annual
range of the seasonal changes in sea level is about 35 m off the south Zhejiang coast, where the highest value of 20 cm occurs
in September, and the lowest of-15 cm occurs in March. The reason may be mainly due to the seasonal variations of climate
and river run-off, as well as the Taiwan Warm Current. Similar seasonal oscillations in sea level also occur in Bohai Gulf,
Yellow Sea, East China Sea and the South China Sea.
The beach process of south Zhejiang is strongly affected by the seasonal oscillations in sea level. The width of beach is
4 to 6 km, the slope is approximately in 1 : 1000. If the sea level rises or falls 1 cm, the beach submergence or emergence
is led to be about 10 m in width. As a result, the relative equilibrium of beach will be changed by the seasonal oscillations
in sea level. 相似文献

青岛市浮山湾、汇泉湾、崂山湾海滩与海底沉积环境分析 总被引：3，自引：0，他引：3
距今12000a，世界洋面已上升至今日海面以下60m处。而后海面继续回升，在距今6000a时，海面已上升到比今日海面还要高3～4m的位置，这就是汇泉广场下面存在海相地层的原因。也是唠山太清官门前存在干枯小泻湖的原因。大约在距今6000a时，青岛市的浮山湾、汇泉湾、唠山湾已经形成，并在海湾中，形成最初的海湾沉积。自那时以来，崂山湾变化不大；而浮山湾、汇泉湾则发生明显的变化。浮山湾展示为宽阔的沙滩形态，自上世纪60年代在燕儿岛建立船厂以来，大面积的沙滩已经消失。目前所见海岸完全为人造海岸，现已不存在海滩。汇泉湾与汇泉广场的填平有关，早期的海岸线，有可能到达中山公园的院墙一带。现在所见的第一海滨浴场也是人为建设所致。 相似文献
