西部十二省、自治区、直辖市旅游竞争力的组合评价

对一个地区的旅游竞争力进行评价有助于客观地了解该地区旅游业的发展状况,而科学合理的评价依赖于评价指标和评价方法的选择。本文提出了合理选择指标的原则,并在所构建的旅游竞争力评价指标体系中引入了＂软＂指标。由于单一评价模型的评价结果各不相同,本文引入组合评价模型对西部十二省、自治区、直辖市的旅游竞争力进行评价,然后采用斯皮尔曼等级相关系数对组合评价结果进行检验,结果显示本文采用的组合评价方法与其它评价方法的一致性最高,说明该方法能比较客观综合地反映旅游竞争力状况。最后,通过聚类分析,进一步验证了本文方法的有效性。     

SEISMIC BEHAVIOUR OF A R/C WALL: NUMERICAL SIMULATION AND EXPERIMENTAL VALIDATION

This paper describes the numerical simulation of the seismic behaviour of a mock-up of a six-floor building, constituted by two parallel R/C walls and experimentally tested on a shaking table. Within the scope of an international benchmark the mock-up was submitted to three earthquakes with intensities up to 0.71 g, which induced nonlinear behaviour in the concrete and reinforcement. For the numerical simulations concrete is discretised with 2D finite elements, and its behaviour reproduced via a constitutive model with two scalar damage variables. Steel rebars are discretised with 2-noded truss elements, and their constitutive behaviour under cyclic conditions reproduced by the Menegottb-Pinto model. Specific attention is devoted to Rayleigh damping, focusing on two different strategies: (i) disregarding the damping contribution, or (ii) adopting a damping matrix that takes into account the stiffness changes during the nonlinear analyses. Main results and strategies for simulating the benchmark axe presented, with emphasis on the comparison between the numerical and the experimental results, which show good agreement when the damping contribution is neglected.     

文化消费者对秦腔展演空间的感知与地方认同——以“易俗社”与“陕西省戏曲研究院”为例

戏曲地理在文化展演空间感知与认同方面的积极探索,对深入拓展文化地理学的空间文化隐喻与再现等研究内容具有重要意义。基于微观尺度探讨了文化消费者对秦腔剧院的感知与认同差异,显示出秦腔展演空间对传递与隐喻地域文化特性、功能和意义有着重要影响。文化消费者在获得秦腔蕴含陕西地域文化记忆的同时,对秦腔地域文化内涵的审美性及其传递的文化价值功能性特征给予显著认同,体现出秦腔的社会群体教育功能价值的重要性;不同消费者对空间主体的价值取向存在差异,“我者”对有共同爱好和价值追求的“他者”产生亲切感、对群体则产生归属感,基于展演空间,秦腔文化生产者、经营者和消费者构建了一个地域文化共同体。     

旅游市场细分研究述评

旅游市场细分已逐渐成为旅游市场营销领域的研究重点之一。本文对国内外相关文献中的旅游市场细分研究进行了归纳总结,着重对聚类分析、卡方自动交互检验和自组织神经网络等三种目前比较常见且有效的市场细分方法进行了比较分析,希望为旅游市场细分的进一步研究提供参考。     

SIMULATION OF THE CYCLIC BEHAVIOUR OF R/C RECTANGULAR HOLLOW SECTION BRIDGE PIERS VIA A DETAILED NUMERICAL MODEL

In the search for robust constitutive models suitable for reproducing the performance of bridge piers during a seismic event, this paper details the simulation of the cyclic responses of four rectangular hollow section R/C bridge piers. These four R/C bridge piers were built at scale 1/2.5 and tested experimentally. Both tall and short piers are considered, covering situations where bending or shear are of relevance. Furthermore, the four piers were reinforced according to rather different design strategies: (I) the first is a 30-year-old bridge designed without allowance to the seismic action, and (ii) the second is a bridge fulfilling the EC8 provisions. The detailed constitutive model that provides the numerical predictions includes two submodels: one with two scalar damage variables, reproducing the tensile and compressive degradations of concrete, and the other is based on the Giuffre-Menegotto-Pinto formulation, simulating the cyclic behaviour of the re-inforcement. The Damage Mechanics submodel is implemented at the Gauss points of the finite elements that discretize the concrete, whereas the steel submodel is implemented on the 2-noded truss elements adopted for the rebars. A comparison between the numerical and the experimental results is discussed in detail in this paper.     

THE ATLANTIC ROMAN TRADE DURING THE PRINCIPATE: NEW EVIDENCE FROM THE WESTERN FAÇADE

In this paper new evidence is presented for long‐distance trade in the western Atlantic in the Roman period, chiefly from Augustus to the second century AD, on the basis of documented shipwrecks and numerous amphora types. Well‐dated contexts from northern Portugal and Spain, as well as similar sites in northern France and Germany, suggest a thriving trade of amphora‐borne commodities during the Principate. The Atlantic route was initially developed during Augustus' campaigns against the Cantabri and Astures, and later consolidated with the exploitation of the mines in the north‐west of the Iberian Peninsula. Supplying the Roman armies in the German Limes gave a new impetus to this commercial route, complemented by the conquest of Britain.     

清代中期徽州山区生态环境恶化状况研究——以棚民营山活动为中心

本对清代中期徽州山区外来棚民的基本状况、棚民营山活动的内容与类型、棚民营山活动给山区生态环境造成的破坏以及徽州社会为遏制生态环境恶化所采取的应对举措等方面作了分析与探讨。章认为,清代中期徽州山区生态环境的严重恶化,主要是由外来棚民所从事的简单粗放、掠夺式的营山活动造成的。在长期饱受生态环境恶化之苦情况下,徽州山区社会采取了驱禁棚民与封山育林,调整产业种植结构相结合的标本兼治的应对措施。     

社会空间视角下全域旅游空间正义性解读

以往学术界对旅游产业和旅游行为的空间认知,多从物质空间视角出发而忽视了其社会属性,导致在产业自身发展受限的同时,也引发了一系列社会、文化和生态问题。本文借助社会空间思想对全域旅游进行文本解读认为：全域旅游在物质空间上从“景区”拓展到“全域”;在抽象空间上结合产业发展、市场需求、旅游活动和社会影响等方面的特征强调社会关联性;在社会实践中将物质和抽象空间统一于社区居民的生活空间中,具有理论上的合理性。因此,全域旅游从社会空间视角定位我国旅游发展问题,将区域可持续发展、社会空间公正和居民生活质量的提升作为最终落脚点和价值诉求,不仅在理论上具有指导性,而且还体现了社会主义国家对空间人本价值和社会公正的追求。     

马家浜文化生业模式初探——来自杨家遗址和马家浜遗址的植物考古学证据

马家浜文化的稻作农业研究是学术界较为关注的问题,基于此前对古水稻和水稻田的研究,研究者多认为其稻作农业已经处于较为发达的阶段.本文通过近年对杨家、马家浜遗址出土大量植物遗存的分析,推测马家浜文化稻作农业发展的关键阶段应始于马家浜晚期,水稻在此阶段成为主要食物资源.并根据对水稻粒型的统计学分析,发现在马家浜晚期,粒型的增大出现一个飞跃,应与耕种技术的进步有关.粟的发现暗示着旱作农业的南传可能存在陆路的传播路线,是将来工作中需要关注的问题.
