前秦时关中氐人分布的武都是指侨置武都郡。侨置武都郡始于曹魏。曹魏为与蜀汉争夺陇右,将武都氐人迁徙至关中,并先后在小槐里和美阳设置武都郡以进行管理。西晋江统的《徙戎论》反映出此时关中武都氐聚居的地方未置武都郡。十六国初期屠各刘氏和羯族石氏先后统治关中,将大量氐羌迁往关东,因此这一时期在关中侨置武都郡缺乏现实基础。苻健立国关中后,在战略要地宝鸡附近侨置武都郡,是其氐人本位政策的体现。北魏时侨置武都郡始领县级行政单位,统治范围扩大,标志着氐人的关中化,同时它也是太武帝平定盖吴叛乱时分化关中南道氐人的重要战略举措。西魏北周立国关中后受政区滥置影响,武都郡领县减少。隋开皇间侨置武都郡在当权者废郡、保留州县的地方行政政策的影响下消失于历史舞台。 相似文献

陕西安康紫阳北五省会馆壁画是目前陕西省境内发现的最大的一处建筑壁画,为了解其颜料组成,本工作采用X射线荧光、偏光显微镜、X射线衍射、激光显微拉曼光谱及扫描电镜能谱分析相结合的分析方法,对颜料样品进行了分析。结果表明,北五省会馆壁画除正殿发现一处红色染料外,其他均为无机颜料;红色颜料主要是铅丹、朱砂、铁红;绿色颜料为氯铜矿、石绿、斜氯铜矿;蓝色颜料的主要成分是普鲁士蓝、smalt、石青;黄色颜料为雌黄、铁黄;褐色颜料的主要成分是铁红及铅丹的变色产物二氧化铅;黑色为炭黑;白色颜料主要是铅白,且多使用铅白作为调色颜料。研究结果对于了解清代民间壁画的制作工艺,丰富对陕西建筑壁画的认识具有重要意义。 相似文献

结合陕北公路交通与经济发展的实际,应用1998-2007年度的数据,运用主成分析、相关性、回归模型、弹性分析等方法,对经济转型期陕北公路交通与经济发展效率进行了综合分析评价。结果发现,陕北公路交通与经济发展之间相关度较高,两者之间的最优回归方程可表示为Logistic曲线函数,交通发展指数对经济发展指数的平均弹性系数大体在0.42-0.58之间波动。在综合经济发展过程中,原来较为落后地区的公路交通基础设施与经济发展会逐步趋向协调;公路交通基础设施的改善是经济发展不可缺少的条件之一,但其边际效益会逐渐减小。最后,建议在当前阶段,为实现陕北经济的顺利转型和健康发展,应建设形成多种运输方式协调发展的综合交通运输体系。 相似文献

陶榖曾先后在后晋、后汉、后周和北宋任官,是五代宋初文人的典型代表之一。其性格偏激急躁,追求名利,行事作风为当时人和后世所诟病。然而,陶榖的形象通过史料和文学作品的加工处理而典型化、脸谱化,并不能够完全反映其真实面目。通过对陶榖家庭背景和行为的具体分析,可以对陶榖其人有更加真实全面的了解,同时也能够更好地认识五代宋初所面临的士风重建问题。 相似文献

In 2009, the Sino-Japanese Joint Archaeological Team recovered the large-sized rammed-earthBuilding Foundation Ⅲ in the south of the Northern Wei palace city. This foundation is located to the north of ChangheGale and Building Foundation Ⅱ and the due south of Taiji Hall. It is the main body of a hall-typed architectureconsisting of the large-sized rammed-earth foundation, the rammed-earth partitions and column network composed oframmed-earth plinths and column pits. The side doors on the eastern and wester... 相似文献

北宋时期,驿传分离,传递公文的事务由递铺承担,分步递、马递与急脚递三种。然而关于急脚递的传递方式是马递还是走传则众说纷纭。本文在有限材料的基础上大胆做一个推测,认为急脚递的传递方式本应乘马,但受马匹来源所限,至中后期以后不得己而采取走传的方式作为补允。 相似文献

Medium to large natural catchments are often more spatially heterogeneous than small catchments or single landforms. Attempting to model landform evolution of large areas is consequently more complex. This paper demonstrates that modelling landform evolution in medium to large catchments can be improved by calibrating the model to smaller, more geomorphologically homogenous sub‐catchments. The paper investigates landform evolution in the Ngarradj catchment in the Northern Territory of Australia (a medium scale catchment of approximately 67 km2). The catchment is complex and contains two distinct landform regions; an upland plateau region with highly dissected sandstone and shallow, sandy soils, and a lowlands region with gentle, wooded slopes and floodplains with deep, sandy soils. The SIBERIA landform evolution model is calibrated and applied to the Ngarradj catchment. The complexity of the Ngarradj catchment is incorporated into the modelling by dividing the catchment into three sub‐catchments (Swift Creek (SC), Upper Main (UM) and East Tributary (ET)) which are relatively homogeneous and for which hydrology and sediment transport data are available. A discharge‐area relationship and long‐term, sediment loss rates for the catchment are derived based on an annual series flood frequency analysis of a 20 year runoff record predicted in a previous study. Sediment transport modelling incorporates both suspended and bedload sediment loss. The denudation rates derived using these data are 37, 63 and 77 mm kyr?1 for the SC, UM and ET sub‐catchments, respectively. Model predictions indicate that the UM sub‐catchment will have the greatest mean erosion. This is balanced by the large amount of deposition that will occur in the upper Ngarradj valley of the UM sub‐catchment. Further deposition occurs on the floodplain of Ngarradj, with the area between the SC and ET/UM (up‐stream) sub‐catchments experiencing a small net accretion of sediment (15 mm kyr?1). 相似文献

This article demonstrates that Fianna Fáil's efforts in 2007 and thereafter to reconfigure as an all-Ireland party represented a volte-face in policy. From an historical perspective, since Fianna Fáil's establishment in 1926, consecutive leaders from Éamon de Valera to Albert Reynolds in the 1990s consistently refused to remodel the party on an all-Ireland basis. Rather than participating in Northern Ireland mainstream politics, Fianna Fáil was fixated with firstly securing, and then maintaining, a republican government in the south of Ireland. Accordingly, in the words of Lemass speaking in 1964, any “Southern interference in the North's affairs” was habitually ruled out by the Fianna Fáil leadership. 相似文献

Abstract Eider duck down is a raw material used in northern coastal areas. In Norway the resource has been of special importance in the archipelago of Helgeland, where there is a specialized production developed and managed by women. There, the eider duck is seen as part of the livestock. The local people build houses for them, tend their nests and look after them during brooding. The down left in the nests by the birds is gathered, dried and cleaned in a very demanding, labour-intensive process. The eiderdown is then used in down quilts and pillows. Down is known from written sources as an important trade item, particularly from the end of the Middle Ages. The increasing bourgeoisie wanted the light and warm down quilts for their beds. Already around AD 890 Othere from Hålogaland (North Norway) told King Alfred in England that the Saami paid him fugela fe?erum (feathers or/and down) in tax. However, the use of down as a raw commodity used in trade must have started earlier, something the archaeological record might reveal. In any case, pillows and quilts of feathers or down are known from high-rank burials from Late Iron Age Scandinavia and Western Europe. 相似文献

Five isolated molars from two localities in the Northern Territory, the middle Miocene Bullock Creek and late Oligocene Kangaroo Well sites, are assigned to the new miralinid genus Barguru, which includes the three new species: Barguru kayir, Barguru maru and Barguru kula. The Miralinidae was previously thought to be restricted to the late Oligocene and early Miocene, but the occurrence at Bullock Creek extends the time range of this family into the middle Miocene. Analysis of metaloph development in the Miralinidae suggests that loph formation in this family followed a different trajectory to that of phalangerids. 相似文献
