THE UNIQUENESS OF THE AMERICAN RELIGIOUS LANDSCAPE

ABSTRACT. The assemblage of objects that constitute the publicly visible religious landscape of the United States—houses of worship and a variety of church‐related enterprises—deviates so markedly from its counterparts in other lands that we can regard its uniqueness as a significant argument for American exceptionalism. The diagnostic features in question include the extraordinary number and variety of churches and denominations, their special physical attributes, the near‐random microgeography of churches in urban areas, and, most especially, their nomenclature and the widely distributed signage promoting godliness and religiosity. Such landscape phenomena suggest connections with much‐deeper issues concerning the origin and evolution of American society and culture.     

漯河市近40年土地利用及景观格局变化特征研究

本文以河南省漯河市为例,以遥感解译的漯河市近40年来土地利用数据为基础,运用GIS叠置分析、土地利用转移矩阵等空间分析方法,结合景观格局指标,研究其改革开放以来土地利用及景观格局变化特征,为优化土地资源配置及科学的城市规划提供依据。结果表明:(1)1980年至2015年间漯河城镇用地面积呈显著增加趋势,扩张主要占用耕地;(2)林地和农村居民点用地总体呈增加趋势,2000年来其他建设用地面积迅速增加;(3)漯河市各景观类型总体呈平衡发展态势,耕地优势度有所下降,建设用地优势度不断上升;(4)人口增长与经济发展、交通条件改善及政府政策变动是影响漯河市土地利用变化和景观格局演变的主要因素。     

江西省丹霞地貌特征及其控制因素探讨

江西省的丹霞地貌主要分布在30余个白垩纪红层盆地中，总共有228处，数量位居全国之首，以鹰潭市龙虎山世界地质公园的丹霞地貌最为典型和知名。根据形态特征，将江西省的丹霞地貌划分为山峰、陡崖、崩积体、峡谷、洞穴及其他微地貌等六大类。燕山构造旋回晚期（主要是白垩纪），在地壳伸展拉张的构造背景下，江西省形成了一系列北东走向的陆相断陷盆地，从盆地边缘到中心依次沉积红色冲 洪积扇相砾岩、河湖相砂岩和泥岩，在信江盆地的中部还发育沙漠相风成砂岩。红层岩相是丹霞地貌演变的基本物质基础，对丹霞地貌的分布具有重要影响。在喜马拉雅构造旋回中，这些红层被构造抬升、切割，随后在风化、流水侵蚀及崩塌等外动力地质作用下形成了红色陡崖坡及一系列侵蚀地貌，即丹霞地貌。以龙虎山世界地质公园核心景区仙水岩为例，用面积高程积分方法对江西省丹霞地貌的演化阶段及其主控因素进行了分析。仙水岩景区地层出露一致，丹霞地貌整体处于老年早期的残丘阶段，地貌侵蚀程度较强；由于水系溯源侵蚀，景区内不同部位地貌的演化阶段、类型及面积高程积分值（HI值）不尽相同。本文对江西省丹霞地貌基本特征及控制因素的分析和总结研究将加深对各类丹霞地貌成因的理解，推动丹霞地貌国际化进程，也为其他湿润气候区丹霞地貌地质遗迹的合理利用提供参考。     

澜沧江流域云南段景观格局分析

流域作为一个特殊的地理生态环境区域,流域景观空间格局状况是进行流域环境资源管理的基础依据。针对澜沧江-湄公河国际河流上游云南段,基于遥感监测所获得的土地覆盖斑块信息,就该地区景观格局进行分析研究。初步结果表明：研究区内景观类型丰富,不同景观类型斑块大小的平均水平,以及斑块密度差异明显;山区早地斑块景观,作为人类驱动影响的直观外在表现,它对本流域山区景观格局具有主导作用。     

广州白云山风景区植被景观空间关联分析

本文借鉴群落生态学种间联结的概念,采用2×2列联表,通过方差检验、X2检验与联结指数对白云山风景区的植被景观各类型间的空间关联性进行了定量分析.结果表明,空间关联能有效地分析植被景观类型之间的空间关系.尽管白云山植被景观各类型之间呈现出正关联,且它们之间的关联很松散,具有很高的独立性,但是人类活动的干扰通过建筑等方式呈现出指射状扩散,这就使得植被的发育与发展与其呈现极其显著的空间相互排斥作用.由于植被斑块破碎,相互交错,空间异质性高,景观要素或者斑块类型表现出十分复杂的空间镶嵌的分布格局.通过景观关联度分析,大体上推断出5种植被景观要素类型之间的总体空间布局关系与规律为"果园(E)-常绿针阔混交林(B)-常绿阔叶林(C)-疏林草地(D)-常绿针叶林(A)",以及12大主要植被斑块类型之间的空间关系"B2-B1-C1-C18-(C15)-C16-C17-C19-C7-C2-D-A1".     

于田绿洲景观动态变化遥感研究

运用遥感和GIS技术,以及景观生态学的方法,利用1989年Landsat TM影像,1999年、2001年的Landsat ETM影像,建立相应的空间图形库系统,研究了近二十年于田地区的景观变化,从景观斑块特征、斑块的空间变化方向和剧烈变化类型角度对该地区景观的时空演变进行了动态描述。并结合多年的实地调查,对产生这些变化的原因进行了定性及定量化研究。     

Comparative studies of Danxia landforms in China

Danxia geomorphology originates from China. This paper studies the spatial distribution and differences in characteristics of Danxia landforms. Based on relevant research and investigations, three congregated areas of Danxia landform in China are discussed in this paper. They are the southeast area (including Jiangxi, Fujian, Zhejiang, Hunan and Guangxi provinces), the southwest area (the transitional zone of Yunnan-Guizhou Plateau and Sichuan Basin) and the northwest area (including Longshan mountain and along the banks of the Huanghe River and its anabranches). Not only the conditions of geology and geography of the three areas but also the differences of Danxia landforms of the three areas are analyzed. The Danxia landscape, characterized by upright-shaped peaks, Danxia mesa, stone wall, cave and vertical cave, "Danxia natural bridge", "a narrow strip of sky" and so on, often presents in the southeast area. The landscape of southwest area is characterized by Danxia escarpment faces and waterfalls. In the northwest area, the Danxia landscape has the traits of arid areas simultaneously, for example, mud-coating type, columniation type, board type, moreover, it is greatly different between these environmental factors such as the microclimate, water, wind, and the loess cover. Finally it explores the causes which lead differences in landform and also explains the landform formation process and its mechanism with reference to the rates of crustal uplift, the tectonic red-basin, and the external processes including working of running water, weathering, biogenic, gravity in each area of Danxia Landforms in China.     

Road construction and landscape fragmentation in China

The landscape fragmentation caused by road construction has many direct and indirect impacts on wildlife and ecosystems. By using the GIS and statistic software of fragmentation computation, a comprehensive index, road-induced landscape fragmentation index (RLFI), is proposed to quantify the degree of landscape fragmentation resulting from different levels of road constructions. The results show that road-induced fragmentation index in China ranges from 0.987 to 3.357, with a mean of 1.846 in 2002. The regional differences of landscape fragmentation are obvious and scoring sequence is: North China (2.65) > East China (2.62) > Central China (2.60) > South China (2.51) > Southwest China (2.34) > Northeast China (2.19) > Inner Mongolia (1.88) > Northwest China (1.67) > Qinghai-Tibet Plateau (1.65). The anisotropic analysis indicates that the variation of fragmentation index in east-west direction is larger than that in south-north direction.

Re-viewing the Entrapment controversy: Megaprojection, (mis)representation and postcolonial performance

Becoming the tallest building in the world in the mid-1990s, the Petronas Towers was the centre piece of an image of national progress and development that Malaysian authorities sought to project internationally. The release of Fox Movies' Entrapment in Malaysia in May 1999 provoked political outrage and popular disappointment at the way in which the Petronas Towers in Kuala Lumpur had been spliced alongside riverside ‘slums’ filmed in the town of Malacca some 150 km away. This paper provides a critical reading of the spliced scene in the movie. At one level, the angry response of the Malaysian Prime Minister, Dr Mahathir Mohamad, to the scene diagnoses a geopolitics of asymmetrical representational power. However, I show how Mahathir's criticism of Entrapment in Malaysia was as much a defence of domestic political legitimacy (and national economic investibility) as it was ‘opposition’ or ‘resistance’ to hegemonic ‘Western’ (mis)representation. In addition, while the material and symbolic work of reimaging Kuala Lumpur had sought to negate (neo)orientalist imaginings of ‘Asian’ cities, the controversial scene rendered visible environmental ‘underdevelopment’ that has no place in a modern (vision of) Malaysia. Entrapment thus performed something in inducing Malaysian cities and citizens to ‘clean up’ their act, to practice ‘fully developed’ ways of seeing, being and being seen.
