用趋势面方法讨论汉江中下游地区新石器时期大溪文化(6.3~5.0ka B.P.)、屈家岭文化(5.0~4.6ka B.P.)和石家河文化(4.6~4.0ka B.P.)遗址空间过程,发现汉江中下游地区新石器文化的空间演化大致分两阶段:(1)屈家岭文化时期遗址沿汉江干流、涢水向上游扩散;(2)石家河时期文化遗址则以收缩为特征,主要集聚在丹江-枣阳-随州一线。结合本区中全新世气候和地貌变迁过程,认为汉江中下游遗址分布格局和遗址高程变化主要受古洪水和湖面扩张胁迫影响,遗址扩散与集聚过程特征和农业生产、文化融合等社会因素密切相关。 相似文献

通过对澧阳平原优周岗遗址剖面沉积样品孢粉分析,重建了该区5500 a B.P.~4000 a B.P.气候、水文、植被变化和人类活动历史。结果表明：距今5500~5200年大溪文化晚期,气候环境较为适宜;距今5200~4000年的屈家岭—石家河文化时期,气候暖湿程度先升高后降低,转折点在4800 a B.P.左右。其中,距今4200~4000年的石家河文化晚期,气候向干凉化发展。孢粉组合显示优周岗遗址周边一直有湿润生境存在,且在屈家岭文化中晚期和石家河晚期出现湿生草本、蕨类孢子和藻类的明显增加,反映两次水文变化过程。优周岗遗址大溪文化时期常绿和落叶阔叶林已遭破坏,稻作农业有一定发展,屈家岭—石家河文化早中期稻作规模扩展。然而石家河文化晚期,稻作农业规模明显收缩,可能与区域文化衰落有一定关系。 相似文献

全新世以来南阳盆地的新石器文化以中原类型为主导,但源于汉水中下游的屈家岭文化和石家河文化深刻影响了南阳盆地史前文化演变的内容和过程。除石家河期遗址集中分布于盆地南缘的低地外,仰韶文化、屈家岭文化和龙山文化的人类遗址均分布于100~200 m地势和缓的岗地区。盆地内史前文化相互角逐的动力源于中原型和江汉型两种原始农业的消涨,因而旱作农业快速发展期对应仰韶文化和龙山文化的南扩;粟作农业的衰落对应屈家岭文化和石家河文化的北进。南阳盆地史前时期的生业模式序列表现为：仰韶文化早期的采集捕捞业、仰韶中晚期的粟作农业、屈家岭时期的稻作农业和石家河—龙山时期的稻粟混作业。其中,屈家岭文化后期生产工具的精细化、家庭畜牧业的规模化改变了先民的食谱结构。 相似文献

莱州湾南岸中全新世聚落遗址时空分布特征及其环境背景 总被引：2，自引：2，他引：0
基于ArcGIS10.3平台对莱州湾南岸中全新世聚落遗址的高程、坡度、坡向、濒河度等指标进行分析,得出该时期聚落遗址的时空分布及演变特征,并结合全新世莱州湾南岸的环境背景,探讨全新世环境演变对聚落遗址分布及演变的影响。研究表明：① 全新世莱州湾南岸的聚落遗址数量、出现频率及在总数中的比重基本呈现明显的先增后降的倒V型（非对称）变化趋势。② 遗址高程分布具有一定的规律性,几乎所有时期的遗址点均分布于高程范围在0~29 m的地区,而大汶口文化时期遗址高程分布范围为10~29 m。从坡度来看,聚落遗址主要分布于坡度范围在0~4°的平缓地区;从坡向来看,古人大多集中在南向、东南向和西南向的位置。后李文化至龙山文化时期,河流对聚落选址的影响程度逐渐降低。③ 8.5~6.9 ka B.P.气候总体进入温暖期,且冷暖波动,干湿交替,后李文化由此得到发展;6.9~4.5 ka B.P.出现了短暂的降温,但整体较温和,优越的自然条件促进了大汶口文化的发展;4.5~4.0 ka B.P.左右气候条件较大汶口文化时期略干,但在此基础上新石器文化仍得到进一步发展,并于龙山文化时期进入鼎盛阶段;4.0 ka B.P.左右气候突变,出现剧烈降温事件,变化幅度超出了人类的适应能力,岳石文化随之衰落。④ 海水入侵限制了人类活动,而古湖泊和古河道的形成为古人生活质量的提高创造了天然条件。 相似文献

山东北部地区聚落遗址时空分布与环境演变的关系 总被引：4，自引：1，他引：3
利用GIS软件对山东北部地区聚落遗址时空分布特征进行分析,并结合双王城剖面沉积环境分析和前人研究成果探讨了聚落时空分布与环境演变之间的关系。结果表明:距今8000-5000 年间,在气候温暖湿润和海面相对较高的环境背景下,人类活动主要集中在海拔相对较高(20~200 m),地形较为平坦(坡度< 2°)的洪积台地和冲积平原上;西部平原地区由于地势低洼,容易积水而发生水患,因而很少有遗址分布。距今5000 年之后,气候暖湿程度降低,海平面持续下降,人类活动范围明显向海扩展;西部低洼地区在气候变干和海面降低的双重影响下,自然环境得到改善,也开始被古人广泛开发利用。这一时期区域文化繁荣发展,逐渐形成社会结构复杂、城邦林立的初期文明。然而距今4000 年左右,由于气候变化和洪患灾害加剧,史前文化开始明显衰落。商周时期气候环境趋于稳定,文化发展再次兴盛。北部滨海平原地区随着生产技术的进步,人类适应区域资源环境条件,在早期农业人群难以定居的滩涂地上形成以盐业生产为主要经济活动的聚落群。 相似文献

近年来新疆盆地平原区域湖泊变化原因分析 总被引：26，自引：4，他引：26
由绿洲及其所在荒漠盆地平原与周边山地系统共同组成的新疆地域系统，是我国西北干旱区的主要部分之一。由于荒漠盆地平原系统不产生径流，因此，地表水、浅层地下水和泉水、湖泊都必然地以相邻的山地系统为供给水源地。从山地进入荒漠盆地平原的河流就成为主要供给渠道。博斯腾湖、艾丁湖、艾比湖1995年以来，湖水水位明显升高，湖水面积的不断扩大，从湖泊水面面积的演变过程，主要水源变化，气温略微上升，降水显著增多诸因素综合系统分析，说明在全球气候背景下，区域气候和水文变化周期与人类活动是影响其变化的主要原因。 相似文献

8500 a BP以来长江中游平原地区古文化遗址分布的演变 总被引：2，自引：0，他引：2
本研究建立了8500 a BP以来长江中游平原地区,从新石器时期至明清时期7534个古文化遗址的GIS数据库,利用ArcGIS软件,从环境考古学的角度,对不同时期古文化遗址分布的地貌类型、海拔高程、坡度特征进行了系统分析。研究结果显示,不同时代的文化遗址的空间分布特征存在显著差别：1) 新石器文化遗址主要分布在平原边缘的山前台地—岗地和高冲积平原等海拔高程适中的地区,海拔高程较低的平原中心区与海拔较高的山地则分布很少;2) 西周以后,文化遗址分布高程呈现下降趋势,从山前台地—岗地、高冲积平原向平缓的低冲积平原转移;秦汉至明清时期,文化遗址则主要分布在海拔高程更低、坡度平缓的低冲积平原和湖积—冲积平原;3) 不同时期的文化遗址空间分布模式,反映了不同生产力水平下人类活动对自然环境变化的响应特点。 相似文献

中全新世黄河流域耕地格局重建及对原生植被的影响(英文) 总被引：1，自引：0，他引：1
Yangshao culture is the most important mid-Holocene Neolithic culture in the Yellow River catchment,and thus,a study on the impact of human activities on the environment is important.In the current study,the distribution pattern of the cultivated land in late Yangshao culture is reconstructed using GIS tool and site domain analysis(SDA).The results show that the cultivated land during 5.5-5.0 ka BP was mainly distributed in the Weihe River valley,Luohe River valley,northwestern Henan Plain,Fenhe River valley and eastern Gansu region,especially concentrated in the Xi’an-Baoji line of the Weihe River valley.At that time,at least 37,000 km 2 of lands were reclaimed in the middle and lower reaches of the Yellow River,and 132,000 km 2 of lands were affected by agricultural activities.Human activities had become the driving force of land use/land coverage.Charcoal records indicate that the ancestors of Yangshao culture burnt forests for reclamation,leading to the decrease of arbor pollen at 5 ka BP in core areas of the Yangshao culture.The areas that were significantly affected by human activities accounted for 3.2% of the Yangshao culture influenced area,while the moderately affected areas accounted for 20.1% of Yangshao culture influenced area.Meanwhile,92% of the land areas on the edge and outside of the Yangshao culture influenced area were not affected by human activities.The arbor pollen in these areas did not decrease until 4.0 ka BP. 相似文献

Holocene environmental changes around Xiaohe Cemetery and its effects on human occupation,Xinjiang, China 总被引：1，自引：0，他引：1

The Xiaohe Cemetery archaeological site (Cal. 4–3.5 ka BP) is one of the most important Bronze Age sites in Xinjiang, China. Although the surrounding environment is an extremely arid desert now, abundant archaeological remains indicate that human occupation was common during certain periods in the Holocene. Field investigations and laboratory analyses of a sediment profile near the Xiaohe Cemetery indicate that while the regional environment was arid desert throughout the Holocene there were three episodes of lake formation near the site in the periods 4.8–3.5 ka BP, 2.6–2.1 ka BP and 1.2–0.9 ka BP. Geomorphic and hydrological investigations reveal that a lake or lakes formed in a low-lying area when water was derived initially from the Kongque River and then shunted into the Xiaohe River basin. Low amounts of active chemical elements in lacustrine sediment between 4.8–3.5 ka BP indicate abundant and continuous water volume in the lake; the content of active chemical elements increased between 2.6–2.1 ka BP but was still at a relatively low level, suggesting a declining amount of water and diminished inflow. Between 1.2–0.9 ka BP there was a very high content of active elements, suggesting decreased water volume and indicating that the lake was stagnate. In contrast, the general climate condition shows that there had a warm-humid stage at 8–6 ka BP, a cool-humid stage at 6–2.9 ka BP and a warm-dry stage at 2.9–0.9 ka BP in this region. The hydrological evolutions around Xiaohe Cemetery did not have one-to-one correspondence with climate changes. Regional comparison indicates that broad-scale climatic conditions played an important role through its influences on the water volume of the Tarim River and Kongque River. But, the formation of the lakes and their level were controlled by geomorphic conditions that influenced how much water volume could be shunted to Xiaohe River from Kongque River. Human occupation of the Xiaohe Cemetery and nearby regions during the Bronze Age and Han-Jin period (202 BC–420 AD) corresponded to the two earlier lake periods, while no human activities existed in the third lake period because of the decreased water volume. 相似文献

The Huaihe River basin of Anhui is not only a transitional zone of physical geography, but also a convergent area of many cultures in China. It is one of the sensitive ecotones to global changes and the birthplace of Chinese civilization. Using the field archaeological data and the sporo-pollens and the age data of the drilling cores, we analysed Neolithic cultural development and environmental evolution in the Huaihe River basin of Anhui. According to the combination of some research results in archaeology with environmental evolution research, this paper discusses the relationship between culture and environment in the Huaihe River basin of Anhui. The Neolithic cultural development was strongly impacted by the environmental change. The primitive culture (Shishanzi) was developed in the beginning of the Holocene Megathermal Period with distinct regional feature of the culture. From 6.5 kaBP to 5.5 kaBP, the climate changed warmer and wetter. The frequent occurrence of flood and waterlog due to such a climate regime and high sea level caused the earth’s surface environment deteriorated in the Huaihe River basin of Anhui and the interruption of the Neolithic cultural development, hence a lack of archaeological sites. From 5.5 kaBP to 4.0 kaBP, the climate changed from wet to dry, the natural environment was propitious to human survival. Dawenkou Culture and Longshan Culture flourished in this period. The Neolithic cultural development, the number of the sites and their distribution characteristics of the sites in the study area differed apparently from those in Central China and Shandong Province. 相似文献

在对渭河流域东部全新世黄土剖面磁化率、粒度、Rb/Sr、CaCO3等气候指标测定分析的基础上,结合已测定的光释光（OSL）年龄和古文化研究的最新成果,探讨了该区环境演变与人类古文化演进的历史及其相互关系。研究发现,在9.34~6.77 ka BP全新世最适宜的气候条件下,在7.80~7.30 ka BP出现了老官台文化,之后发育了仰韶早期文化;在全新世中期6.77~5.48 ka BP干冷气候初期出现了仰韶文化最繁荣的庙底沟类型文化;中后期随资源环境的持续恶化,该区出现了仰韶文化衰落的西王村类型文化;在全新世中晚期的5.48~3.12 ka BP气候再次发生好转推动了该区龙山文化的发展;4.60~3.76 ka BP期间频繁发生的洪水事件可能进一步强化了人地关系,并进而推动了该区文化进入夏商人类文明时期;3.12 ka BP以来趋于干冷的气候在推动该区人类文明进一步发展的同时,人类活动对环境影响的强度和范围也日益加大。渭河流域古文化得以延续发展至今,一方面说明气候环境的变化并未超越先民适应能力的范围,另一方面也说明渭河流域具有先民维持生存和发展的优越资源环境条件。 相似文献

The temporal-spatial geographic distribution of archaeological sites and its feature between 10.0–2.8 ka BP(ka BP= thousands of years before 0 BP, where "0 BP" is defined as the year AD 1950) were determined, based on GIS spatial analysis in the Poyang Lake Basin. The relationship between geographic distribution of sites of different periods under subsistence existence of ancient civilizations, climate and environmental change was investigated. The results revealed numerous archaeological sites of the Neolithic Age(10.0–3.6 ka BP). The sites were mainly located in the northern part of the Poyang Lake Basin, a hilly and mountainous area with many river terraces suitable for the development of human civilization. The number of archaeological sites rapidly increased during the Shang and Zhou dynasties(3.6–2.8 ka BP) and spread widely on the floodplains of the middle and lower reaches of Ganjiang River and onto the west, south, and southeast beach areas of the Poyang Lake. Holocene records of climate change suggested that it was possible that climate fluctuations had a great impact on human evolution in the study area. Before 3.6 ka BP, westward and northward expansion of Neolithic cultures in the Poyang Lake watershed occurred under the background of climate amelioration(becoming warmer and wetter). The ancient people lived in the hilly areas with high elevation. The simple mode of a fishing and gathering economy was mostly suited to this area in the early Neolithic Age. The scope of human activities was expanded and cultural diversity developed in the late Neolithic Age. However, with population growth and increasing survival pressure in a dry-cold climatic stage after 3.6 ka BP, this simple living mode had to be abandoned, and various forms of economy, the majority being agriculture, were developed on flood plains of the lower reaches of numerous rivers around Poyang Lake. This promoted flourishing of the Bronze culture of South China. 相似文献
