基于活动类型的郊区大型居住区居民生活空间重构——以回龙观为例

本文基于550份调查问卷和第一手的访谈资料,以北京著名的郊区大型居住区——回龙观文化居住区为研究对象,探讨了包括居住空间、工作空间、购物空间和游憩空间在内的郊区大型居住区生活空间重构的特征与机制,分析了居民生活空间重构与郊区化的关系。研究表明,近10年来,居民对远距离居住-工作空间错位有较强的承受能力,以回龙观为代表的郊区大型居住区在形成居住空间郊区化、商业和休闲空间的分散化和多中心化方面发挥了重要作用,也验证了过去10年中北京郊区化发展的高强力度。回龙观社区职能由单纯卧城向综合型社区的演变成为居民多种生活空间重构的背景,另外,不同类型的生活空间之间相互联系,某种生活空间变化往往导致另一种或几种生活空间跟随发生变化。回龙观的案例给郊区的城市规划工作带来一定的启示。     

不同类型道路密度对公共空间盗窃犯罪率的影响——基于ZG市的实证研究

道路密度对犯罪分布存在影响已得到大多数学者的证实,但忽略了不同类型道路属性的差异对犯罪的影响。不同类型道路在社会-建成环境等各种属性方面存在较大的差异,因此明确不同类型道路密度对公共空间盗窃犯罪率存在的影响有助于犯罪的防控。基于此,本文以派出所为单元构建多元线性回归模型进行研究。研究发现,不同类型道路密度对公共空间盗窃犯罪率影响不同：城市次干道、城市支路和其他可通车道路密度对公共空间盗窃犯罪率有正向影响;不可通车道路密度对公共空间盗窃犯罪率有负向影响;城市主干道密度对公共空间盗窃犯罪率影响不显著。不同类型道路社会-建成环境的差异是公共空间盗窃犯罪率不同的原因。研究结果可为犯罪精准防控提供指导。     

复杂情境中的日常活动可视化与应用研究

时间地理学以时空路径为代表的符号系统由于具备抽象、简明、直观等特点,在地理学及其他社会科学领域得到了广泛传播与应用。随着GIS与地理可视化技术的不断进步、高精度时空行为数据的批量生产等,真实地理环境中个体时空运动轨迹的三维可视化技术也在不断进步。信息化社会的到来与城市社会转型等使得现代社会中的人类日常活动变得十分复杂,时间地理学由于直观刻画时空间中人类活动的时空连续性与复杂情境性而备受关注。本文首先界定了人类日常活动复杂情境的分析维度,包括日常情境、企划情境、地理情境、社会情境、技术情境等,并在此基础上将绝对时空间坐标系下的时空路径拓展到相对时空观下多维活动序列的可视化表达。其次,简单说明Daily life与VISUAL-Time PAc TS/energy use等可视化工具,介绍时空路径在复杂情境性下的可视化、模式挖掘及个案分析。最后,案例分析个体与群体尺度上活动情境可视化方法在家庭成员间分工与互动、日常活动模式差异与家庭能源消耗差异等方面的应用。     

基于价值转移方法的我国游憩活动价值评价

鉴于目前我国在构建价值转移模型中存在的限制因素,本文采用基于Meta分析的价值转移方法并尝试利用国外游憩活动价值评价的实证研究结果,构建基于Meta分析的国际间价值函数转移模型,估算了我国10种游憩活动的日平均消费者剩余.通过将价值转移模型估算的游憩活动价值“转移值”与国内97个游憩价值评价的“真实值”做比较,对价值转移模型的有效性和可靠性进行统计检验,平均转移误差为18.74％.最后,总结了提高我国Meta回归价值转移模型的具体、可操作性方法及途径.     

Modeling skeletal traits and functions of the upper body: Comparing archaeological and anthropological material

The aim of this study is to look at upper body functional modifications caused by mechanical loading. We look at 4th lumbar vertebra as well as fibrous humeral musculoskeletal stress markers (MSMs). This study uses information provided by magnetic resonance images of living individuals from the University of Oulu Hospital data banks (N = 91), archaeological skeletons from Sweden (N = 54) and England (N = 61), and autopsied skeletal collection of early 20th century Finns in Natural History Museum, University of Helsinki (N = 48). The lumbar vertebrae and MSM are subjected to mechanical loading caused by the upper body weight and loads lifted and/or carried. We hypothesized that the vertebral size reflect body size, habitual mechanical loading and the overall skeletal robusticity as mechanical competence to withstand mechanical loading standardized to body size, which has decreased over millennia. For Helsinki material occupation, age and sex is known and the material was used in Niinimäki (2011). In the study by Niinimäki (2011) MSM were found to be affected by the intensity of muscular action as well as body size and age. This study is reviewed here in light of re-analysis of the data to follow the current anatomical understanding of the entheses as well as viewing MSMs as a part of upper body functional complex. Only fibrous entheses were included in the re-analysis. Furthermore, due to small number of females where activity intensity could be assessed, females were dropped from the re-analysis.

仪式活动视角下的集体记忆和象征空间的建构过程及其机制研究——以南京大学校庆典礼为例

仪式活动是集体记忆、象征空间与地方认同建构源头,因其研究有助于揭示城市各空间尺度内的公共生活竞争的内在机制,因此已成为西方文化地理学的重要研究命题;但此类以仪式活动为视角,揭示集体记忆、象征空间建构过程及其机制的研究,在国内极少。鉴于其研究重要意义,文章以南京大学校庆典礼为例,运用文献研究、田野考察、访谈等多种定性与定量方法,探讨了自上而下的仪式活动,即校庆建构集体记忆、象征空间、地方认同的过程及其机制,为校园特别是新校园或扩建校园的纪念物建设与规划提供科学依据。     

潮州古城旅游社区主客活动秩序研究

个体日常活动行为的时空特征及秩序反映出个体对空间利用的时空需求。本文选取潮州古城作为案例地,以周末为典型日,采用日常活动地图收集居民与游客活动数据,基于活动分析法及Arc GIS空间分析从流动、分布与状态三个方面探究大型旅游社区的主客活动秩序。研究结果表明:古城的空间功能在原有的生活功能基础上演化出旅游功能,并保持着主客活动的秩序性,但其流动模式由于交通管制条例的约束及主客的共同占用,暗藏潜在矛盾;由于主客活动意图的不同,决定了活动安排上时间与空间的错位,在时空资源配置上表现出"分时共地"、"共时异地"的嵌合特征;"共时共地"之时,由于古城的空间足以容纳主客的活动,加之"商业性好客"的驱使,使得主客活动仍能保持秩序化。由于潮州古城具有着相对独立的社区结构,社区旅游发展成为社区秩序重构的重要机遇,合理的规划内容和途径能有效促进旅游社区生活功能与旅游功能的协调,在利益主体的协商与适应中构建了主客活动的新秩序。     

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.
