宋元之际棉花传入中国,明清时期得到了初步发展,逐渐替代桑蚕业成为主要的经济作物之一。在明清发展的基础上,进入二十世纪二、三十年代后,由于棉种的改良与推广,国内近代机器纱厂的勃兴和华北日益加深的农业危机,尤其是华北近代铁路网的兴建等诸多因素的共同影响,华北地区植棉业迅速发展,棉田面积与原棉产量大幅度增加,并出现了专业化生产的趋势,一些棉花生产专业区逐渐形成。 相似文献

名宦、宗族与地方权威的塑造--以山西寿阳祁氏为中心 总被引:2,自引:0,他引:2
本文以明清时期山西寿阳县的祁氏宗族为个案,考察了一个地方大族在基层社会如何运用各种社会资源,逐渐建立其权威的过程.当这种权威逐渐消失后,民众却依然保留着对祁氏权威的历史记忆,继续塑造这一地方权威和利用这一地方资源.通过对这一个案的分析,不仅可以丰富我们对明清时期华北宗族在传统中国基层社会中的生存状态的了解,还能加深我们对明清华北地区的宗族势力与名人资源、地方权威状态与乡村权力结构等问题的认识. 相似文献

在当代农村基础设施建设的浪潮中,农村集市在交通、通讯等现代化设备的影响下也发生了巨大的变化,最底层的农村集市削弱了,部分中心集市的职能也受到影响,只有极少数的核心集镇得到了加强,形成了规模更大的社会经济区域,这就是次县级区域。 相似文献

晚清华北的集市和集市圈 总被引:15,自引:2,他引:13
本文利用华北数十州县的方志,特别是利用形成于光绪早期的《青县村图》、《深州村图》中的丰富资料,对晚清时期华北的集市和集市圈做了较详尽的研究。本文认为,华北各州县集市数量参差不一,甚至差距很大,集市数与州县人口数、村庄数及土地面积的关系,亦无有规则的比率。集市圈即集市与赶集村庄的空间构成,所包含的村庄多至近百村,少则二三村,甚至一村。本文以自己的研究成果对美国学者施坚雅关于中国乡村市场和社会结构的理论、公式提出了质疑。 相似文献

ABSTRACTMorphometric analysis offers an alternative or augmentation to traditional archaeobotanical methods to address differences within and between plant species and their remains, refining and enhancing taxonomic resolution. Morphometrics, the measurement of size and shape, and the multivariate statistical analysis of generated quantitative variables, have long played a major role in biological research, including plant taxonomy and systematics, although its application in archaeobotany is relatively recent. Over the last few decades, there has been an increasing interest in the use of morphometrics for analysing a varied range of archaeological plant materials (mainly seeds, pollen, phytoliths, and starch grains). In particular, morphometrics have contributed to the study of the domestication and spread of many cereals world-wide, as well as that of other taxa including legumes, underground storage organs (USO), and fruits (such as olives, grapes, and dates). This paper reviews current methodologies, recent applications, and advances in the use of morphometrics in archaeobotanical research, discusses its role in exploring major research questions, and suggests possible future directions for its use. 相似文献

Within the last 30 years, geographical information systems (GIS) have been used increasingly in the training of geographers. On the basis of the philosophy of technology and instrumental genesis, we sketch how the use of instruments interacts with learning processes and outline how this can be studied. We empirically analyse students' learning processes and the influences of teaching practice in an introductory course in GIS. We show that students have different strategies for creating their personal instrument for spatial thinking and how teaching interacts with the students' learning processes. Finally, we discuss how GIS may gradually alter future professional development of geographers. 相似文献

The author's primary aim in what follows is to fully articulate Chantal Delsol's critique of late modern universalism as an attempt to depoliticize the individual for the sake of replacing politics with morality. The result of this depoliticization is a quasi-pantheistic cosmopolitanism that not only effectively denies the significance of individuality, despite rhetorically lionizing it, but also undercuts the freedom of individual conscience that makes moral choice possible. Genuine political prudence and moral judgment are subsequently replaced by the rigid exactitude of a technocratic analysis that reintroduces the "clandestine ideology" it was, despite protestations to the contrary, intended to eliminate. The unhappy paradox produced by the attempt to replace the necessary limitations of political judgment with the universality of a priori moral decree is that a new set of culturally and historically idiosyncratic political attachments are surreptitiously introduced beyond the pale of reasonable debate and disagreement. Delsol's measured response is not a precipitous rejection of universalism as such but a rehabilitation of it that recaptures the Christian moral realism at its core. 相似文献
