The Paleolithic sites in South China have caused controversy regarding human behaviors in response to the rapidly shifting environment of the late Pleistocene. However， chronometric and high-resolution proxies are absent from interpreting the paleoenvironmental evolution. Here we present the chronology， grain size parameters， and geochemical elements records from the Hejialing (HJL) site in South China to reveal the crucial aspects of environmental evolution， and human occupation. The geochemical record shows that during MIS 5e–5a， northern Hunan experienced the influence of summer monsoon and maintained a warm and humid climate. The laterite layer began to develop. During MIS 4， the climate transitioned to dry and cold state， leading to the attraction of hominins to the HJL area due to the abundant water and lithic raw material resources， resulting in their establishment of a short-term camp. The HJL site was primarily inhabited by hunter-gatherer societies within a forested environment. From MIS 4 to MIS 2， Hunan experienced a prolonged period of dry and cold climatic conditions， with a brief rainfall recovery occurring in late MIS 3. Diminished vegetation and resource availability compelled human populations to broaden their activities and undertake migrations. The HJL site was abandoned amid the arid phase of MIS 2. The HJL area gradually became buried beneath eolian dust deposition (EM1) from distant sources and riverine dust from nearby sources (EM2)， and the site was informed. In MIS 1， During MIS 1， the climate shifted to a warm and humid state， marking the emergence of early agricultural practices. As an essential part of South China， the environmental evolution process and diverse survival strategies employed by hominins in Hunan are vital for explaining how the paleoenvironment drove human occupation during the Late Pleistocene.

史前城址作为早期城市演化的关键组成部分,与气候、地貌以及水文等区域环境因素密切相关。然而,目前的研究在考虑史前城址相关的区域环境因素方面存在不足。本文基于长江中游地区典型遗址走马岭古城的上津湖钻孔沉积记录和完整的年代框架,结合元素地球化学等气候代用指标分析,重建了中晚全新世走马岭古城遗址的区域沉积环境演变过程,并探讨了其与人类活动的关系。研究发现:(1)6.4—5.3 ka BP期间,CIA、Rb/Sr、Mn/Ti值总体较高,Be、Saf值呈相反趋势,指示气候较温暖湿润。此时屈家岭下层文化时期的先民在走马岭修建城址。(2)5.3—4.7 ka BP期间,CIA、Rb/Sr、Mn/Ti值上升至峰值,气候暖湿。稻作农业得到发展,屈家岭文化在走马岭古城达到鼎盛。其中4.7—4.6 ka BP期间,粒度参数异常上升,指示古城发生强降水导致的洪水事件。(3)4.7—4.2 ka BP期间,气候转向凉干,古城的石家河文化逐渐衰落。(4)4.2—2.4 ka BP期间,CIA、Rb/Sr、Mn/Ti值降至最低,气候变凉干,古城在3.9 ka BP被废弃。(5)2.4—0.3 ka BP期间,CIA和Rb/Sr值回升,Saf和Be值下降,气候回暖。0.8 ka BP左右,上津湖形成。0.3—0.1 ka BP期间,CIA、Rb/Sr值大幅降低,Be和C/N值异常升高,指示在明清小冰期的鼎盛期,走马岭气候寒冷干旱。但是当时围垦等人类活动频繁,初级生产力高。走马岭古城的城内水源主要依赖东南侧的蛇子岭水体,雨季时打开西水门,洪水通过壕沟排入上津湖。旱季时关闭西水门,靠城外蛇子岭水体引水供城内用水。后期气候转向凉干时,水体枯竭导致走马岭古城的壕沟系统失去作用,古城被废弃。

沉积物中黑碳记录了百年来区域生物质燃烧特征变化。本文以海州湾入海潮滩采集的岩芯沉积物样品为研究对象,采用热光反射法(TOR)分别对沉积物黑碳、焦炭和烟炱进行测定,分析探讨海州湾近百年来生物质燃烧演变过程。利用相关性分析、主成分分析和特征比值法分析黑碳含量的历史变化和可能来源,试图揭示该区域百年来能源结构的转变过程。结果表明,近百年来沉积物黑碳、焦炭、烟炱质量分数垂直变化幅度较大,分别在0.507~1.281 mg·g^(-1),0.395~1.080 mg·g^(–1),0.112~0.389 mg·g^(-1)范围内变化。其中,黑碳质量分数高值出现在20世纪80年代中后期(0.873~1.029 mg·g^(-1)),而低值出现在20世纪20年代到20世纪中叶期间(0.675~0.751 mg·g^(-1))。不同区域黑碳分布比较发现,我国东部边缘海地区比青藏高原和瑞典湖泊高出10倍,但发达国家黑碳通量峰值出现时间早,反映了黑碳沉积与区域工业化水平和人类活动相关性显著。黑碳特征比值法(char/soot)的源解析结果表明,黑碳的来源中化石燃料燃烧占48.8%,是生物质燃烧的4.2倍。根据相关性分析、主成分分析和char/soot比值结果分析,黑碳在1950年以前主要来源是生物质燃烧,在1950年以来煤炭燃烧、工业源、交通源比重增加,主要和区域人口、工业总产值、能源消费等因素有关,人类活动占据主导。研究结果为进一步理解该区域黑碳污染状况及制定未来海州湾地区的生态环境管理政策提供参考。

Paleosalinity records of the Tianluoshan site are derived from measurations data of clay mineral, boron, strontium, barium, after field sampling in three profiles of the Tianluoshan site. The relative sea level changes are discussed according to the lab results. The record indicates that the region where the Tianluoshan site located has witnessed at least three times of relative sea level high-stand before, during and after the Hemudu period. Based on previous researches, this paper also focuses on discussing several environmental elements, the inter-relationships between environmental condition, human activities and development of the Hemudu culture comprehensively.

At about 173 ka BP of the late period of mid-Pleistocene, the second terrace of the river had been formed as a result of uplift happening in Shangshan area because of the climate, sea level change and tectonic action. Between 173-75 ka BP, aeolian deposited on the terrace, a layer of reticulate red clayey soil about 80-100 cm thick deposited and developed under the warmer and higher temperature. In the last glacial period, the drop of the temperature and the decrease of the precipitation induced the dust-storms increased, A layer of Xiashu loess about 1.0-1.5 m thick accumulated on Shangshan terrace in the last glacial, which has the reticulate red clayey soil buried. At the beginning of the Holocene （11500 a BP-）, temperature went higher gradually and precipitation got more, the pre-persons moved on the Shangshan terrace （11,400-8600 a BP）, which is one of the most important archaeological sites, and can connect the paleolithic culture with Neolithic culture. It could be assumed from the results that the lower reaches of the Yangtze River are the home of rice cultivation, too. The lower place to the west of the Shangshan site experienced the two cycles process of the fluvial facies and the lacustrine facies, indicating that the water source of the pre-historical Shangshan is the river water or lake water. Two AMS 14C age proved the water source disappeared more than 1000 years ago.
