一、屯垦的发端及其形式 屯垦是按一定编制组织人力进行规模不等的垦殖。它导源于春秋时代齐相管仲首倡的“寓兵于农”的主张。秦始皇兵统六国后,采取“逐戎狄,徙谪实之”的办法、把属于赵、齐、楚、卫等国的罪犯,先后7次迁徙到河套以北和南方的象郡、桂林、南海诸郡,屯垦实边,就地建立了粮饷基地。这种军屯,实为军管下的犯屯。主父偃称赞 相似文献

This paper presents a method for dealing with unpaired skeletal elements in order to approach the questions of (1) how many animals are represented in an assemblage; and (2) how large these individuals were. The method is designed for use with fish remains and can easily be extended to paired elements. It is shown how the interplay between the data appropriate to the solution of both problems may be compared in order to provide a method of verification of the results arrived at by standard methods of assessment of the minimum number of individuals. 相似文献

For some 15 years the authenticity of a group of small pottery pieces, claimed to have originated in the Hui Hsien area of China, has been the subject of academic discussion and some dissension. The thermolumines-cent dating of 22 such pieces from 4 independent collections is reported following a review of archaeological evidence for the origin of the material and of scientific investigations that have previously been made in investigation of its authenticity. It is concluded that all the pieces are of modern origin and not some 2300 years old as their stylistic forms might suggest. 相似文献

Summary. This study, based on evidence from archaeological surveys and excavations in southern Greece, demonstrates two major shifts in the subsistence economy during the Neolithic. In the EN and MN periods the presence of large villages in locations near reliable water-sources and permanently moist or seasonally flooded soils of high and sustained productivity illustrates a village farming economy concentrating on arable agriculture. The first economic shift occurred in the late MN-LN with occupation of highland caves and islands, indicating increased sheep/goat pastoralism, fishing, and perhaps hunting, with a reduced number of farming villages present in the plains. The second shift took place in the FN-EBA, when a dispersal of agricultural settlements into dry upland regions indicates expanding plough agriculture and pastoralism, important factors contributing to the development of the flourishing EBA economy. The expansion of settlement was most marked in southeastern Greece, and it is suggested here that the extensive grazing areas provided by the open vegetation and mountainous terrain of this dry region, and its relative scarcity of well-watered fertile lowlands, may have stimulated the LN-FN expansion of pastoralism. 相似文献

<正>The infrared camera is a curious object for the animals of Changtang.Often covered in camouflage or army green,it looks very"professional".But once I saw the photos they took,I knew the camouflage did not work at all.Most animals could see the cameras without any problem.Some of them showed various degrees of interest in the cameras,while others acted indifferently.To tell the truth,it is not easy to hide something in Changtang. 相似文献

This essay takes its point of departure from the emergence of the concept of presence in the field of history and theory. The essay suggests that the emergence of presence is related to the events of September 11 and signals a weariness of the postmodern condition and a longing for the real. Advocates of presence, the essay argues, have stressed how the material traces of the past move us in the present, and in doing so have played down the problematic relationship between past experience and historical representation, which was a concern of the linguistic turn. The essay argues that this interest in the trace points to a shift away from the meaning‐making of symbolic practices and toward the moment when the master signifier enables (symbolic) meaning to occur. This indicates that there is a desire for the real at play in the move toward presence. Through an analysis of Eelco Runia's concept of presence, the essay argues that this desire for the real is related to a repression of Darwin's evolutionary framework, which has been considered bad taste in the social sciences and humanities since the end of the Second World War. 相似文献

The authors quantitatively analyze the effect of railroad construction on agricultural land values in the often overlooked, agriculturally oriented, trans-Mississippi West. This region is unique in American history in that, at the end of the nineteenth century, the railroad itself preceded widespread settlement. Using a hedonic model, they show that railroad transport increased agricultural land values in this region by more than 20 percent, which had a larger impact than recent studies have found for other regions. Moreover, the authors found that the addition of a railroad to a county significantly increased its growth in land values. This finding is contrary to that of existing studies. Finally, the authors show statistically that the railroad and land values were not endogenously determined, lending credibility to the causality of the results presented in their hedonic and growth models. These results indicate a valuable alternative approach to use in the historical analysis of transportation infrastructure and its impact on land prices. 相似文献
