Human settlement and agricultural development are closely linked to local geomorphological and climatic environments.However,the variation in agricultural systems in different environmental and prehistoric contexts remains unknown.We report new archaeobotanical and radiocarbon dates from 34 Neolithic and Bronze Age sites in the Hutuo River Valley(HTRV)in north-central China and compare them with updated archaeobotanical studies in the Sushui River Valley(SSRV)and Henan Province(HNP),to explore the similarities and differences of agricultural patterns under different geomorphologic and climatic environments in north-central China.Our results reveal that humans consistently cultivated foxtail and broomcorn millet in the HTRV from the Miaodigou(6000–5700 cal.a BP)to the Shang-Zhou(3600–2256 cal.a BP)period,despite the introduction of wheat and barley into the area around 4000 a BP.Climate conditions and hilly landforms in the HTRV,SSRV and some parts of the HNP led people to develop foxtail and broomcorn millet dry land farming practices between 7000 and 3000 a BP.Alternatively,in other areas of the HNP,the climate conditions and alluvial plains enabled people to develop a mixed agriculture of millets,soybeans,and rice from 7000 to 4000 a BP,with the addition of wheat between 4000 and 3000 a BP.Farmers’different agricultural technologies and interactions with foreign cultures may have also influenced the formation of different agricultural patterns in the three regions between 7000 and 3000 a BP.Population growth during 7000–3000 a BP can explain the overall propensity of the higher-yield foxtail millet rather than broomcorn millet as the main cultivated crop.In the HTRV,however,higher proportions of broomcorn millet(as compared to the SSRV and HNP),may reflect the greater drought and heat tolerance of broomcorn millet,representing an adaptive agricultural strategy in the river valley.

Refined chronology of prehistoric cultures and its implication for re-evaluating human-environment relations in the Hexi Corridor,northwest China

The reconstruction of high-resolution chronologies for prehistoric cultures is a prerequisite for understanding the history of human evolution and its relationship with environmental change, and is valuable for exploring the trajectory of transcontinental cultural exchanges in prehistoric time. The Hexi Corridor of northwest China was one of the earliest centers for long-distance culture exchange in the prehistoric world. The timing and sequence of cultural changes in this area remains poorly understood resulting from the lack of radiometric age control. This paper presents a refined radiocarbon(14 C) chronology to resolve the timing of human occupation and cultural evolution in the Hexi Corridor. Radiocarbon dating of crop remains, which have an annual life cycle, has the advantage of eliminating problems such as the carbon stored in ‘old wood’. As a result,14C dates from crop remains are used to test the validity of the14C dates derived from charcoal, bone and plant remains. The resultant database of ages is modelled using the Bayesian approach. The updated chronology presented in this paper shows generally good agreement with the original dates used to constrain cultural evolution in the Hexi Corridor. However, the occupation of the corridor by the Shajing and Shanma Late Bronze Age-Early Iron Age cultures appears to have taken place ~300 years later than previously thought. On the basis of comparing this updated chronology of cultural evolution with palaeoclimatic and historical records, it is proposed that the collapse of the Shajing and Shanma cultures occurred as a result of geopolitical impact rather than climate change.

Spatiotemporal evolution of prehistoric Neolithic-Bronze Age settlements and influencing factors in the Guanting Basin, northeast Tibetan Plateau

引用

Science China Earth Sciences 2018年第2期61卷 149-162页

作者： cui yifu LIU YuJia MA MinMin MOE Key Laboratory of Western China's Environmental Systems Lanzhou University

For almost two decades, the relationship between prehistoric natural disasters that struck the Guanting Basin in northeast Tibetan Plateau and the destruction of Lajia, an archeological site, has attracted scholarly attention and been widely discussed. Whereas most studies have focused on the impacts of disasters on a single site within the Guanting Basin, few have examined patterns of spatiotemporal evolution of human settlements from the Neolithic to the Bronze Age. Consequently, there is a lack of clarity on the processes and mechanisms underlying the evolution of prehistoric human-land relationships in the Guanting Basin. We therefore examined spatiotemporal variations in settlements in the Guanting Basin during the period, based on the locations, altitudes, and areas of archaeological sites. We found that four sites were located on the third terrace of the Yellow River during the late Yangshao period(5500–5000 cal yr BP) and distributed within a small area. During the period between the Majiayao and Qijia cultures(5300–3600 cal yr BP), the number of sites evidently increased and the scale and distribution of settlements expanded, with settlements generally shifting toward the lower elevation areas of the Guanting Basin.During the Xindian period(3400–2700 cal yr BP), the number and scale of sites showed a downward trend and the distribution of settlements contracted. The Xindian settlement underwent altitude-based spatial differentiation, with some groups moving to areas at higher altitudes and others remained in lower altitude areas. Moreover, we found that the number, scale, and distribution range of Neolithic and Bronze Age sites in the Guanting Basin were closely related to the evolution and distribution patterns of prehistoric cultures in the regions of Gansu and Qinghai, which were further affected by climate change and agricultural development. Furthermore, there is no evidence that the altitudinal distribution pattern of Neolithic and Bronze Age settlements in the Guanting Basin was influenced by pale

The Integration of Farmers and Nomads: Archaeological Evidence for the Human Subsistence Strategy in Northwestern China during the Han Dynasty

Acta Geologica Sinica(English Edition) 2020年第3期94卷 603-611页

The integration of farmers and nomads in northwestern China during the Han Dynasty(206 BCE ~ 220 CE) provides a crucial opportunity to reconstruct the material exchanges, formation and development of the Silk Road in antiquity. The subsistence strategy is arguably an effective proxy for the integration of various groups of people(e.g. farmers and nomads). In this paper, we have reported new stable isotope data from the Huangwan tombs dated to the Han dynasty in middle Gansu, which was the key juncture between the Han and Xiongnu empire, in order to fill the gap and further understand the substance strategies employed by the local people. According to the results of plant remains and stable isotopic data, millet farming, the typical agricultural activities for the Han Chinese in the Central Plains, was also the primary lifestyle for the Huangwan people in the mid Gansu. More importantly, this shows fundamentally remarkable difference from the agricultural practices in the Bronze Age Gansu Corridor, which were based on a variety of crops, including wheat, barley and millet. This major shift in the subsistence production at Huangwan can be correlated to a wider historical background in which the Han empire showed increasing political and military presence in the Gansu Corridor, indicating that local indigenous nomads followed the lifestyle of Han Chinese(e.g., millet farming), and/or the Han immigrates maintained millet farming.

作为社会复合生态系统的重要理论,城市生态位一直是研究重点,但缺少尺度效应的深入观察。以浙江省为例,首次将地市⁃区县⁃乡镇三个尺度进行横向对比,构建了多个尺度适用的城市生态位评价模型。研究通过生态位宽度、生态位重叠度、生态位分异指数和引力模型方法,对825个乡镇,71个区县和11个地市的3个尺度的生态位进行了探讨。研究结果表明:从生态位宽度来看,浙江省的生态位发展不均衡,地市尺度呈现反“C”结构,衢州市和丽水市生态位宽度最小,杭州市、湖州市和宁波市生态位宽度最大。且研究尺度越大、生态位宽度越大,则尺度效应作用越大。从生态位分异程度来看,随着尺度的缩小,分异程度逐渐增大,其中社会生态位分异程度最大。表明尺度效应在发展越不平衡的生态位维度中作用力越大。从生态位重叠度和引力模型来看,生态位宽度小的区域往往面临竞争难以摆脱困境,而生态位宽度大的区域更容易将竞争转化为合作。出现强者越强,弱者越弱的两极分化现象,丽水市和衢州市竞争最激烈而杭州市和宁波市合作更为便利。浙江省各地市可以通过资源再造、协同发展和借力帮扶策略优化区域发展。

马家窑文化是甘青地区新石器时期的主流文化,其时空演化和生业模式转变过程的研究取得了较大进展,但其不同发展阶段的地貌环境和水文条件的变化却仍不清晰。本文借助GIS方法和遗址域的概念,采用定量手段分析了马家窑文化不同时期遗址分布的地貌背景和汇水累积量的变化,并以此推论这些不同的地貌环境所反映的土地利用方式及其与生业模式之间的关联。分析结果表明,马家窑文化在不同时期的遗址域内有不同的平地等级和汇水累积量分布,这些指标所反映的土地开发、占用模式与当时的生业模式有很大关系。这项工作为理解不同气候背景下史前人类对生存空间和生业模式的选择机制提供了新的视角。

Over the past few years,the flexible quasi-solid-state zinc-ion hybrid supercapacitors(FQSS ZHSCs)have been found to be ideal for wearable electronics applications due to their high areal capacitance and energy density.The assembly of desirable ZHSCs devices that have promising practical applications is of high importance,whereas it is still challenging to assemble ZHSCs devices.In this study,a ZHSC that exhibited ultrahigh areal capacitance and high stability was developed by using an active carbon cloth(ACC)cathode,which could improve ionic adsorption.The as-obtained ACC cathode had an energy storage mechanism due to the electrical double-layer capacitive behavior of Zn^(2+),which was accompanied by the dissolution/deposition of Zn_(4)SO_(4)(OH)6·5H2O.The ACC//Zn@ACC ZHSC device exhibited an areal capacitance of 2437 mF cm^(−2)(81 F cm^(−3),203 F g^(-1) under the mass of ACC with∼12 mg cm^(−2))at 1 mA cm^(−2),an areal energy density of 1.354 mWh cm^(−2) at 1 mW cm^(−2),as well as high stability(with an insignificant capacitance decline after 20000 cycles),which was demonstrated to outperform the existing ZHSCs.Furthermore,the assembled flexible device still had competitive capacitance,energy density and service life when integrated into a FQSS ZHSC.When applied in practice,the device could achieve high mechanical flexibility,wearable stability and output.This study can inspire the development of the FQSS ZHSC device to satisfy the demands for wearable energy storage devices with high performance.

Rational design of oxygen evolution reaction(OER)catalysts at low cost would greatly benefit the economy.Taking advantage of earth-abundant elements Si,Co and Ni,we produce a unique-structure where cobalt-nickel silicate hydroxide[Co_(2.5)Ni_(0.5)Si_(2)O_(5)(OH)_(4)]is vertically grown on a reduced graphene oxide(rGO)support(CNS@rGO).This is developed as a low-cost and prospective OER catalyst.Compared to cobalt or nickel silicate hydroxide@rGO(CS@rGO and NS@rGO,respectively)nanoarrays,the bimetal CNS@rGO nanoarray exhibits impressive OER performance with an overpotential of 307 mV@10 mA cm^(-2).This value is higher than that of CS@rGO and NS@rGO.The CNS@rGO nanoarray has an overpotential of 446 mV@100 mA cm^(-2),about 1.4 times that of the commercial RuO_(2)electrocatalyst.The achieved OER activity is superior to the state-of-the-art metal oxides/hydroxides and their derivatives.The vertically grown nanostructure and optimized metal-support electronic interactions play an indispensable role for OER performance improvement,including a fast electron transfer pathway,short proton/electron diffusion distance,more active metal centers,as well as optimized dualatomic electron density.Taking advantage of interlay chemical regulation and the in-situ growth method,the advanced-structural CNS@rGO nanoarrays provide a new horizon to the rational and flexible design of efficient and promising OER electrocatalysts.

马家窑文化是甘青地区仰韶文化晚期阶段一个重要的文化遗存类型,其以精美的彩陶闻名于世,对于马家窑文化彩陶的交流传播研究受到了学术界的广泛关注.本文运用X-荧光光谱分析法对甘青地区5个典型马家窑文化早期阶段遗址出土的92件彩陶陶片样品和各遗址附近采集的42份红粘土及黄土样品进行化学元素组成分析,追溯彩陶的产源地及贸易.同时基于陶器的起源传播理论,收集整理马家窑文化区遗址出土的粟(Setaria italica)、黍(Panicum miliaceum)农作物以及动物骨骼遗存鉴定资料,探讨马家窑彩陶贸易的动力.Ti/Al-Na/K和主成分分析结果显示宗日文化区宗日遗址的马家窑文化彩陶元素组成特征和马家窑文化主体区域的彩陶一致,表明宗日遗址马家窑类型彩陶是从马家窑文化主体区域贸易而来;马家窑文化彩陶的传播和该地区粟黍农作物的交流传播具有时空一致性,粟黍农业人群沿黄河上游谷地向共和盆地的扩散带来了新的文化元素;宗日文化区和马家窑文化核心区生业模式的差异带来了跨区域间文化交流的动力,这也可能是马家窑文化彩陶贸易的动力.
