吉林省白城市双塔遗址东周时期人骨研究 总被引:1,自引:0,他引:1
双塔遗址是近年来松嫩平原先秦时期最为重要的考古发现,该遗址为建立白城西部乃至科尔沁沙地东部地区汉以前考古学文化的编年序列,廓清相关诸考古学文化的谱系关系,奠定了重要基础;为判断同类遗存年代提供了重要标尺,特别是东周时期人骨标本的发现,是迄今在科尔沁沙地东部地区发现的唯一一份保存较为完整的人骨资料。本文对出土9例东周时期的颅骨(男性6例,女性3例)进行了体质人类学的研究,该组颅骨在种族特征上可归入现代亚洲蒙古人种中的北亚人种范围。在若干古代和现代对比组中,双塔组东周时期居民的体质特征与井沟子东周时期居民、近代蒙古人最为接近,属于先秦时期我国北方地区的"古蒙古高原类型",佐证了这一时期该地区的人口流动。 相似文献

本文对中国现代人群的两性身高差异分布状况及其影响因素进行了分析。选用152处中国现代人群(含69处汉族人群和83处少数民族人群)的男、女性身高数据,计算两性身高差异指数,并对比该指数在南、北方汉族和少数民族人群间的分布差异,同时分析纬度、气候、体格大小与城乡环境因素对两性身高差异程度的影响。结果表明,中国男性的平均身高比女性高出约7.16%(4.72%~9.26%);南、北方汉族和少数民族之间的两性身高差异程度相似,北方汉族和南方汉族两性身高差异程度相似,但北方少数民族的两性身高差异明显大于南方少数民族。此外,两性身高差异程度与纬度、气温年较差和年均风速呈低度线性正相关,与年均气温、年均降水量和年均相对湿度呈低度线性负相关,而与体格大小和城乡环境并无显著关联。这提示遗传和自然环境因素在中国现代人群两性身高差异的区域化演变中更趋主导性,而社会环境因素的影响程度相对较低。 相似文献

距今约7000~6000年的广西灰窑田遗址是顶蛳山文化的重要遗址之一,其所出人类遗骸为探讨岭南地区史前时期渔猎-采集型人群的肢体活动方式、活动强度以及两性劳动分工等问题提供了重要的研究样本。髌骨作为膝关节的重要组成,其形态变异特征在一定程度上可以反应个体膝关节的活动程度与特点。本文采用三维几何形态测量方法对该遗址出土的43例人类髌骨进行分析,从侧别对称性、性别二态性以及年龄差异性等三个方面考察了髌骨的大小和形态差异。研究结果表明,该遗址古人类髌骨发育存在明显的左侧优势,髌尖呈右偏趋势。男性髌骨尺寸较大,但两性髌骨形态未见显著差异。该遗址个体髌骨形态随年龄增长呈现出与股四头肌力量增强、屈伸运动强度与频率增加相关的变化特征。 相似文献

体质量推算作为体质人类学的一项重要研究方法,为衡量古代居民体型提供了新的途径,同时也为解决考古学、历史学问题提供了新的研究思路。本文通过"生物力学"和"形态测量学"两种方法对内蒙古和林格尔县土城子遗址2005年出土的34例战国时期人骨标本进行了体质量推算。统计分析结果表明,该组男性居民的平均体质量约为67.21kg,女性居民的平均体质量约为54.63kg,男女两性之间的差异显著。通过与战国时期内蒙古长城地带井沟子居民的比较分析,土城子男性居民在平均体质量上明显大于井沟子男性居民,并且体质量值整体分布偏高,而女性组则差异不显著。结合考古学、历史学相关研究材料,该数据为土城子居民为戍边军士的身份提供了进一步的证据。 相似文献

统万城遗址位于陕西省靖边县,是十六国时期大夏国都城所在,历经北魏、西魏、北周、隋、唐、五代、北宋七个朝代共575年。其所处中国北方农牧交错地带,一直是人群往来、交融之地。本文参照《人体测量手册》所列方法对统万城遗址出土人骨进行颅面形态特征的分析。结果表明,统万城遗址出土颅骨是以亚洲蒙古人种为主体,在形态上既存在古人种类型的差异,又表现出多种古人种类型融合的特点,另外还有个体表现出少量欧罗巴人群的性状。统万城遗址居民颅面特征的多态性与融合性,和古代人群演化的历时性特点相吻合,与统万城历史上频繁的人群往来相关,欧罗巴人种因素可能来自粟特人的影响。男女两性居民的主体构成可能有不同来源,随着政治权力主体变化,农人与牧人所占比重也发生了变化。 相似文献

Temporal and geographic variability in adult body size can be a useful indicator of a population's adaptation. The southern African Cape supported foraging populations exclusively until some pastoralism is seen, ca. 2000 BP. This paper describes and interprets body-size patterns among foragers, as deduced from maximum femoral lengths and femoral head diameters, using 127 individually dated adult skeletons from the western (70) and southern (57) regions of the Cape (64 male, 60 female, 3 sex undetermined). Estimated statures are comparable to historic Khoesan samples, but show lower values and greater variance during the fifth/fourth millennium before the present among both sexes and both biomes. Variation in femoral length does not correlate with diet protein, as reflected in stable isotope (delta(13)C and delta(15)N) values. Positive correlations between femoral head diameter and isotopic indicators suggest greater body mass with more reliance on marine protein. A decline in femoral length begins at around 4000 BP, a time when archaeologists suggest that population growth led to the incorporation of lower-ranked food resources, and to reduced mobility. A clearly identifiable linear recovery, beginning at around 3000 BP, greatly predates the earliest evidence of pastoralism on the Cape. Apparent problems of food sufficiency were addressed and solved, within a hunting and gathering economy. 相似文献

Recent studies have linked climatic and social instabilities in ancient China; the underlying causal mechanisms have, however, often not been quantitatively assessed. Here, using historical records and palaeoclimatic reconstructions during AD 10–1900, we demonstrate that war frequency, price of rice, locust plague, drought frequency, flood frequency and temperature in China show two predominant periodic bands around 160 and 320 years where they interact significantly with each other. Temperature cooling shows direct positive association with the frequency of external aggression war to the Chinese dynasties mostly from the northern pastoral nomadic societies, and indirect positive association with the frequency of internal war within the Chinese dynasties through drought and locust plagues. The collapses of the agricultural dynasties of the Han, Tang, Song and Ming are more closely associated with low temperature. Our study suggests that food production during the last two millennia has been more unstable during cooler periods, resulting in more social conflicts owing to rebellions within the dynasties or/and southward aggressions from northern pastoral nomadic societies in ancient China. 相似文献

This paper examines the evolution of the statures of Spanish male and female migrants who entered Mexico between the mid-nineteenth and the mid-twentieth century. Using the information contained in the National Registry of Foreigners created by the Mexican government, the paper also estimates the evolution of the gap between male and female migrants’ heights. The inclusion of women and their heights in the registry allows the estimation of both male and female heights and the analysis of their evolution for a group of comparable individuals. The results show that Spanish migrants to Mexico grew taller between 1840 and 1930, and also reveal their character as a highly qualified group, with heights similar to those of the Latin-American elites and considerably higher than the statures of those who remained in Spain. In the long term, the differences between men and women decreased from more than 10 cm in the cohorts born in the mid-nineteenth century, to around 8–9 centimetres in the early twentieth century, coinciding with a period of profound economic and social transformations. 相似文献

The weight of all bones and the length of humeri, radii, femora and tibiae have been determined in a series of 150 dry, fat-free skeletons from American Whites and Negroes of both sexes, ranging in age from 23 days to 22 years. Six skeletons were eliminated from the series because of evidence of previous illness. A comparison of the lengths of femur plus tibia of this series with the mean statures of a large series of living children at given ages indicates similarity in the growth patterns. Statistical analyses of the data show that the skeletal weight cannot be estimated reliably from age by cither an exponential growth equation or by a logistic function. The weight of the skeleton, however, is related to the lengths of the measured limb bones by allometric equations, and such equations involving each of the four bones are presented for estimation of skeletal weight in the living. Although the standard errors of estimate of the equations based on lengths of each of these four bones differ very little, the radius is recommended over the other three because it is more readily accessible in the living for a roentgenogram and its shadow on the film shows least distortion. 相似文献

Statural growth in human populations is a sensitive indicator of socio-economic well-being, and improvements in socio-economic status are reflected in secular increases in adult height. In the present study, we investigated the statures of historical Korean societies to show how stature changed over time. Applying Fujii's equation, derived from modern Japanese, to the measurement of femora removed from 15th- to 19th-century Joseon tombs, the average heights of Korean adults during the Joseon dynasty were estimated to be 161.1 ± 5.6 cm and 148.9 ± 4.6 cm for males and females, respectively. Plotting statures for successive historical societies against time revealed that Korean heights remained relatively unchanged through to the end of the 19th century, a pattern that differs from that seen in many Western countries in which stature transiently decreases after the Middle Ages. In contrast, a sharp increase in Korean stature was observed at the beginning of the 20th century, similar to trends seen in other nations (although exact timing varies in different countries). There were no accompanying changes of stature sexual dimorphism. The data reported in this study reflect the unique historical experience of Korea; the relative isolation of Joseon society, the late onset of modernization (at the end of the 19th century), and the later occurrence of industrialization (during the 1960s). 相似文献

The commonly used Angelica herbal decoction today is Danggui Buxue Tang (DBT), which is a dietary supplement in treating menopausal irregularity in women, i.e. to nourish "Qi" and to enrich "Blood". According to historical record, many herbal decoctions were also named DBT, but the most popular formulation of DBT was written in Jin dynasty (1247 AD) of China, which contained Astragali Radix (AR) and Angelicae Sinensis Radix (ASR) with a weight ratio of 5:1. However, at least two other Angelica herbal decoctions recorded as DBT were prescribed in Song (1155 AD) and Qing dynasties (1687 AD). Although AR and ASR are still the major components in the DBT herbal decoctions, they are slightly varied in the herb composition. In order to reveal the efficiency of different Angelica herbal decoctions, the chemical and biological properties of three DBT herbal extracts were compared. Significantly, the highest amounts of AR-derived astragaloside III, astragaloside IV, calycosin and formononetin and ASR-derived ferulic acid were found in DBT described in 1247 AD: this preparation showed stronger activities in osteogenic, estrogenic and erythropoetic effects than the other two DBT. The current results supported the difference of three DBT in chemical and biological properties, which could be a result of different herbal combinations. For the first time, this study supports the popularity of DBT described in 1247 AD. 相似文献
