北方有江南:一项景观史的研究

隋唐以降,"江南"不仅是地域概称,亦作为一种美称在北方地区广泛流行。根据各地被称为"江南"的缘由,可大致分为水利型、稻作型、文化型、富足象征型以及景观型。各种类型的"江南"并非泾渭分明,北方各地之"江南"多是几个类型的集合体,是为复合型"江南"。北方"江南"多位于自然条件优越之地,多数"江南"指代地域为一县之隅。"江南"本是对某地社会之赞美,但美称亦会转化为"实累",明代宁夏即为此例。综合来看,传统时代北方民众对"江南"美誉的认可,缘于江南地区的繁荣兴盛,其本质上体现的是对于富足美好生活的向往与追求,亦是传统时代北方民众对于"何谓江南"的理解。     

The Recognition and Utilization of Silkworm Resources in the Hongshan Culture: Focusing on the Unearthed Jade Silkworms

Jade silkworms unearthed from the sites of the Hongshan culture reflect that the mulberry silkworms and tussah silkworms were recognized and utilized in the Liaoxi (west Liaohe River) valley from at least 5.5 to 5 thousand years ago. This not only makes the Yan-Liao region (extending from the Yanshan Mountains to the Liaohe River valley), where the west Liaohe River valley is located, become another prehistoric center of silkworm resource utilization besides the middle reaches of the Yellow River and the lower reaches of the Yangtze River, but also traces the earliest time and the area of the utilization of tussah silkworms in China from Shandong Peninsula in the Han Dynasty to the west Liaohe River valley in the Hongshan period. Meanwhile, the quantitative superiority of jade tussah silkworms implies that wild silkworm resources were still the main source of silk for the Neolithic inhabitants. The understanding and expression means of“taking jade as silkworm” and“turning silkworm into dragon” in the Hongshan culture coincide with those in the Shang and Zhou dynasties, and are a vivid portrayal of the Hongshan culture as a direct root of the Chinese civilization.     

机械切割在土遗址搬迁保护中的应用研究

The Overseeing Mother: Revisiting the Frontal-Pose Lady in the Wu Family Shrines in Second-Century China

Located in present-day Jiaxiang in Shandong province, the Wu family shrines built during the second century in the Eastern Han dynasty (25–220) were among the best-known works in Chinese art history. Although for centuries scholars have exhaustively studied the pictorial programs, the frontal-pose female image situated on the second floor of the central pavilion carved at the rear wall of the shrines has remained a question. Beginning with the woman's eyes, this article demonstrates that the image is more than a generic portrait (“hard motif”), but rather represents “feminine overseeing from above” (“soft motif”). This synthetic motif combines three different earlier motifs – the frontal-pose hostess enjoying entertainment, the elevated spectator, and the Queen Mother of the West. By creatively fusing the three motifs into one unity, the Jiaxiang artists lent to the frontal-pose lady a unique power: she not only dominated the center of the composition, but also, like a divine being, commanded a unified view of the surroundings on the lofty building, hence echoing the political reality of the empress mother's “overseeing the court” in the second century during Eastern Han dynasty.     

Microblade technology and the rise of serial specialists in north-central China

Though present before the Last Glacial Maximum, microblade technology is uncommon in the lithic assemblages of north-central China until the onset of the Younger Dryas (12,900–11,600 calBP). While it is clear that microblades here and elsewhere were connected with mobile adaptations organized around hunting, the attendant assumption that they served primarily in hunting weaponry is not. The archaeological record of north-central China, including excavations at Pigeon Mountain (QG3) and Shuidonggou Locality 12 (SDG 12) in Ningxia Autonomous Region, and Dadiwan in Gansu Providence, and a handful of bone/antler tools slotted for microblade inserts, indicate a more direct linkage to mobility. These data suggest the rise of microblade technology in Younger Dryas north-central China was mainly the result of microblades used as insets in composite knives needed for production of sophisticated cold weather clothing needed for a winter mobile hunting adaptation akin to the residentially mobile pattern Binford termed “serial specialist.” Limited time and opportunities compressed this production into a very narrow seasonal window, putting a premium on highly streamlined routines to which microblade technology was especially well-suited.     

Stochastic Seismic Response of Pipelines with Corrosion

For aging pipelines, corrosion gradually appears inside and outside during in-service time. However, because the uncertainty characteristics of the soil around the pipeline and conveying material in the pipeline, the generation and development processes of the pipeline corrosion would be stochastic processes. This background must be taken into account in the seismic response analysis of the pipeline. In this article, using Markov chain with absorbing barrier, a model simulating the evolution of the pipeline corrosion is presented. This model divides a pipeline into several segments and obtains the distribution probabilities of the cross section areas of the segments. Elastic foundation beam method and random perturbation method are used to obtain the seismic response of the pipeline with corrosion. To validate the proposed method, two pipelines are investigated in detail. The mean and standard deviation of the displacements and stress of the pipeline under earthquake are evaluated by the proposed method. Also, the results of one pipeline are compared with Monte Carlo random simulation. The numerical results show that the proposed model can reasonably predict the seismic response of the pipeline with corrosion.     

论明王朝治理安多藏区的策略及成效

安多在明朝经营整个藏区中具有特殊作用。明王朝把安多看作是经营整个藏区的示范区和桥头堡。明王朝对藏区的治理沿袭元制,并有所突破和创新治理安多藏区的原则是羁縻与怀柔并举,主要措施有“土流参治”、“僧官制度”及官办“茶马互市”等。总体而言,明王朝在安多藏区的治理是成功的,值得肯定的。     

文化廊道范围计算及旅游空间构建研究——以西南丝绸之路(云南段)为例

随着桑地亚哥·得·卡姆波斯特拉朝圣之路(Santiago de Compostela)的成功申遗,以及近年来京杭大运河、丝绸之路申遗呼声的高涨,跨区域大型线性遗产正逐渐成为研究热点。本文在对文化线路和遗产廊道进行中国化的理论解读后,引入了文化廊道的理念。以西南丝绸之路(云南段)为例,在专家评价的基础上,运用地理学的方法,借助于GIS对廊道空间进行分析,提出了确定廊道范围的计算方法,并推导出文化元素"影响力半径"的计算公式;从节点、通道、域面三个方面对西南丝绸之路(云南段)的旅游空间进行了构建,并给出了廊道空间分析、构建的方法和指标体系,为西南丝绸之路旅游开发及其他文化廊道(茶马古道、京杭大运河等)的保护和开发机制研究提供了借鉴。     

城市化空间增长上限确定的研究综述

本文从概念、理论及因素等方面对目前在城市化空间增长约束作用的特征进行了梳理,认为目前的研究存在着区域宏观尺度的把握较少、因素集成分析较少、缺乏直接针对城市用地本身与其他因素的相关关系分析等不足。笔者认为从约束角度开展对城市化空间增长上限的研究工作,关键是如何确定区域水资源安全容量、粮食安全下的耕地最小规模、可恢复条件下生态空间的最小规模或城市生产生活所需的最小生态空间规模等阈值,并提出城市化空间增长上限确定的方法和途径。     

基于旅游影响感知的自然旅游地居民分类及影响因素——以安徽天堂寨景区为例

旅游发展初期的自然旅游地社区居民旅游影响感知分类及影响因素在文献中讨论较少。以天堂寨景区为例利用分层聚类法与多分类名义变量逻辑斯蒂回归模型对居民旅游影响感知群体分类并识别其关键影响因素。研究发现:天堂寨周边社区居民旅游影响感知分为盲目乐观派、社区经济挂帅派、谨慎支持派、悲观反对派,分类的关键影响因素为年龄与居住时间、居住村、现在工作。基于深度访谈数据与研究文献分析了相关因素影响居民旅游影响感知群体分类的内在机制。本研究证实了一个事实:即使在偏远的山区农村社会分化也越来越明显,哪怕是针对像旅游业这样的具体议题,同时本研究也呼应了经典社会学中的社会分层理论。
