中国村镇主体空间行为博弈及对策分析

我国进入快速城市化发展时期以来,在城市化和工业化的推动下,各类村镇主体的空间行为能力逐步增强,在其追求自身利益最大化的过程中,往往出现不理性的空间行为,在农村地区引发出诸多的空间问题。本文以各类村镇主体(农村居民、企业、农村基层自治组织、地方政府)的空间行为为研究对象,运用博弈理论深入分析各类不良空间行为产生的根源,有针对性地提出相关公共政策建议,以期改变其博弈规则,从而有效引导和规范各类村镇主体的空间行为,优化村镇空间。     

城市回族社区的地方性——基于开封东大寺回族社区地方依恋研究

作为中国城市化水平最高的少数民族,回族社区的地方性在城市化过程中受到严重挑战。论文以\"地方依恋\"为理论模型,以开封东大寺回族社区为典型案例,对城市回族社区的\"地方性\"进行深入解读。研究发现,由于围寺而居和强烈的回族认同感,城市回族社区的地方性特征主要受居住时间、文化程度、年龄大小和宗教信仰的深刻影响,地方依恋较深的地方主要在\"寺市并存\"或距离寺市都近的街道,内部空间上存在不同的宗教知识传承模式。这为丰富社区地理尺度的地方依恋理论和揭示回族社区人地关系机制提供了重要实证依据。     

旅游目的地游客感知价值的层次关系模型

顾客价值被认为是竞争优势的新来源,目前旅游领域游客感知价值研究多将感知价值的各维度置于同一层次,这样不利于对游客感知价值概念的深刻理解,也不利于旅游业界从操作层面上提升游客感知价值。本研究基于\"途径-目的\"理论,使用回归分析方法检验了目的地属性层的价值维度与结果层价值维度的关系。结果表明,旅游者对目的地属性层的价值感知显著影响对结果层的价值感知,其中,景观/环境和成本属性是影响中国旅游者体验结果的主导性因素。

Urban geo-archaeology in medieval alzira (Prov. Valencia,Spain)

Alzira is situated in a cut-off meander loop of the Rio Júcar. Geo-archaeological study shows that the Islamic city wall was built during the second quarter of the 11th century AD, at a time when the river had a low-amplitude and low-energy flood regime. After mid-century, overbank silts began to invade the city as peak flood discharge increased, with a spate of destructive floods reflected by high-energy deposits during the late 11th century. Urban expansion within the city wall is dated to the later 11th or early 12th century, interrupted by local abandonment and moderate-energy flood silts. Major construction during the mid-12th century was followed by protracted abandonment (after a siege in AD 1171?) and further, moderate-energy flood silts that redistributed occupation and collapse debris. Reoccupation, during the late 14th century, was terminated by catastrophic floods in 1517 and 1571, after which much of the western end of Alzira was not rebuilt. Following further flood catastrophes during the 17th century, parts of the central walled city remained abandoned until the 19th century. with new occupation atop flood sands of yet another disaster in 1864. The change in flood regime after 1150 was a result of deforestation of the watershed, but progradation of a downstream tributary fan after 1517 created an unstable, aggrading floodplain increasingly prone to severe flooding. Climatic anomalies were responsible for periods of recurrent severe floods, archaeologically verified during the 11th and 12th centuries, and historically documented, beginning in 1318. The geo-archaeological methodology illuminates the constructional and settlement history of Alzira, allows distinction of fluvial and cultural components, and provides the necessary microstratigraphic detail and dating control to document the true complexity of alluvial processes during the last 1000 years.
