南宁市房地产价格分布规律的机助制图研究与开发方向的探讨

南宁市房地产业经历了由沉寂、复苏、火爆到稳步发展的过程．各公司开发的房屋类型相近,但价格差异却很大,价格分布呈现明显的规律性：一是城市中心价格高,边缘与郊区价格低;二是东部城区价格高,西部城区价格低．主导价格分布规律的三大影响因子是地理位置、交通便捷程度和生态环境质量．南宁今后的房地产开发和城市规划建设一要顺应价格分布规律,优地优用、保障房地产开发的高效益;二要加强交通设施建设和环境保护．促进全市房地产的升值;三要因势利导,发展城市副中心,逐步形成多中心的城市建设格局。     

从三分到归一:唐朝前中期岭南政治地理格局的变迁

岭南僻处南疆,地理复杂。隋末大乱之时,地方势力纷纷割据,唐初和平统一岭南后,采取羁縻政策,以原有势力为基础设管州的"都府"。而在都府之上,朝廷以广州、桂州、交州为中心置"统府",以点控面,有效地维护了岭南地区的稳定。但是这种层层管理的"统府三分格局",到高宗乾封二年发生突变,随着邕府和容府的建立,原统府消失,遂形成并立的"五府格局"。可是,最迟8世纪初,唐朝设立岭南五府经略使,统一管理整个岭南的军事。在此前后,岭南选补使、岭南按察使、岭南采访使等陆续出现,在人事、监察、民政等领域,对岭南道全境实施管辖权。因此,"盛唐"的岭南道,表现出明显的"归一"趋势。     

基于GIS的沈阳旧城区叙事空间研究

20世纪60年代,叙事学作为一门学科始于西方历史学、文学领域。直至20世纪末,叙事学开始转向空间领域研究形成空间叙事学,并被逐步应用到城乡规划中,尤其是城乡空间结构等领域。空间叙事学不仅关注城市发展中的物化要素,更加注重物化要素所代表的城市文化和城市记忆等非物化要素的深入挖掘,是探究场所本体与场所精神的重要研究思路。本文从空间叙事学出发,基于GIS平台运用核密度及K函数对古代、近代、现代三个时期沈阳旧城区人工叙事要素和人文事件叙事要素进行点模式量化分析,得出沈阳旧城区叙事空间的总体结构,以及叙事点核、叙事廊道、叙事簇群等叙事空间结构单元,指出沈阳旧城区叙事空间的动态发展性、功能多样性和历史传承性特点,探讨了叙事空间的经济驱动、自然要素、城市定位和交通发展四大演变机制。从人文地理学的视角出发,结合叙事空间理论对沈阳旧城区叙事空间进行分析,结果具有文化地理和城市地理双重属性,丰富了城市研究在该视角下的研究成果。     

International relations and foreign policy in the Australian Journal of Political Science: A review

The Australian Journal of Political Science (AJPS) has evolved from a publication that deliberately relegated articles in international relations (IR) to a secondary status to one that has defined and encouraged leading-edge contributions to that field. This development can be attributed to successive AJPS editorial teams’ realisation that contemporary political problems are increasingly interconnected and that emerging approaches to IR reflect this condition. Several recent and key IR debates that have emerged within the journal’s pages are assigned special attention here: the linking of Australia’s domestic politics to that country’s foreign policy interests and behaviour; in-depth discussions that relate to ongoing trends in the international political economy; critical analysis of national defence and regional security postures; and diverse theoretical perspectives that are increasingly shaping the IR field’s paradigmatic identity. It is concluded that the AJPS is now a leading source of IR thought and discourse.     

Testing settlement models in the early Roman colonial landscapes of Venusia (291 B.C.), Cosa (273 B.C.) and Aesernia (263 B.C.)

This paper examines settlement density and settlement patterns in the Roman colonial territories of Venusia, Cosa and Aesernia, located in three different landscapes of central southern Italy (modern Basilicata, Tuscany and Molise). Using a series of GIS tools, we conducted a comparative analysis of the density and spatial distribution of sites dating to the Hellenistic period (ca. 350–50 b.c.). We used the legacy settlement data collected by previous large-scale, intensive, site-oriented field surveys to test the validity of two competing rural settlement models of early Roman colonization: the conventional model of neatly organized settlements regularly dispersed across the landscape and the recently proposed theory that colonists adopted a polynuclear settlement strategy. After calculating the extent to which the archaeological datasets conform to the regular or polynuclear model, we conclude that only a very small portion of the colonized areas actually meets traditional expectations regarding the organization of early colonial settlements. Our analyses show that the legacy survey data is more consistent with the polynuclear settlement theory, but the data also reveals some completely unexpected patterns, suggesting that early Roman colonial landscapes were more diverse than previously thought.     

An analysis of spatial patterns of toponyms in Guangdong,China

The unique geographical environment and the historical waves of immigration of the northern Han Chinese to the Lingnan region have contributed to the development of a complex and unique culture in Guangdong Province. Four ancient ethnic groups, the Zhuang, Cantonese, Hoklo and Hakka, have resided in this area for centuries. As an important part of local culture, toponyms often survive changes in history and can reveal the temporal differences between the past and present in landforms and the spatial differences in the distribution of different ethnic group populations. In this study, two goals were sought: (1) the adoption of spatial smoothing and interpolation methods to reveal the spatial patterns of the Zhuang, Cantonese, Hoklo and Hakka toponyms based on comparisons among the proportions of those who speak various languages and (2) the investigation of the differences among toponymic layers under regional environmental conditions and the influences of geographic factors using an independent samples t-test and a binary logistic regression.     

峡江地区汉晋南朝花纹砖上的车轮纹饰

文章对峡江地区汉晋南朝花纹砖上的车轮纹饰进行全面检讨。首先将车轮纹饰分为若干种类,其后以发掘报告为依据讨论各类车轮花纹砖的年代,最终归纳出峡江地区车轮纹饰的演变线索。文章以为,峡江地区的车轮花纹砖大约出现在新莽至东汉初期,东汉中晚期至东晋最为流行,南朝仍有发现。文章同时分析了各阶段车轮纹饰的时代特征,并且简要讨论了与车轮花纹砖相关的若干问题。     

基于海量点云数据的大雁塔三维重建

古建筑三维重建已成为历史遗迹保护与修复的重要内容。为了探讨三维激光扫描数据的获取流程、数据处理方法,以三维激光扫描获取的大雁塔海量点云数据为例,研究了古建筑三维重建中点云数据获取与处理的详细过程。联合Cyclone、AutoCAD和3D-Max软件的优点构建了大雁塔真实的横面、剖面、立面模型,其中重点研究了海量点云数据在Cyclone软件中分块建模的方法。结果表明:将拼接好的大雁塔海量点云数据分块建模,不仅加快了数据处理的速度,而且符合精度要求。在点云数据拼接时采用标靶拼接和同名点拼接相结合及测站间两两拼接之后再整体拟合平差的方法,减少了拼接中的误差,使每站拼接误差都不超过3cm。在建模过程中的墙体拟合是上万个点云经过平差计算得到,精度高达2mm。最后在3D-Max软件中组合、渲染和贴图,真实地构建了大雁塔三维立体模型。为古建筑数字化存档和后期的修缮工作提供了重要的依据。
