明清丝绸之路哈密—吐鲁番段“沙尔湖路”研究

明清丝绸之路哈密—吐鲁番段存在一条自哈密西南沙尔湖转西北至鄯善进而抵达吐鲁番的“沙尔湖路”,它与“黑风川道”“小南路”等传统路线均不同。利用《蒙古山水地图》等文献,可对沙尔湖路具体行经进行考证复原。该路沿线地形平坦,有泉水与植被,在明廷与吐鲁番、清廷与准噶尔在哈密的政治和军事对峙阶段曾广泛使用,后因泉湖干涸、气候炎热而中断。     

An Applied Method for General Regional Seismic Loss Assessment—With A Case Study in Los Angeles County

We describe the formulation and application of an integrated general regional seismic loss assessment (RSLA) method for buildings in seismic regions. An efficient method for RSLA is valuable for engineers involved in city planning, risk management, and insurance dealings. In contrast to previously reported methods, the framework presented herein is hazard-based and utilizes a regional rapid seismic hazard deaggregation tool that allows regional assessment to be conducted more efficiently. The proposed technique is implemented as an example to assess general regional seismic loss in Los Angeles County for a ground motion hazard with 10% probability of exceedance in 50 years.     

Iktomi in the Land of the Maymaygwayshi: Understanding Lived Experience in the Practice of Archaeology Among American Indians/First Nations

In discussions concerning American Indians/First Nations and the practice of archaeology in North America, the issues are typically presented in a polarized fashion with American Indians/First Nations on one side and archaeologists on the other. Frequently the literature discusses how archaeologists should modify their practice in response to the needs of American Indian communities. Very little of the literature looks at the roles and challenges faced by American Indians who choose to pursue archaeology. This paper addresses this latter issue by examining my own work among First Nations communities in Ontario, Canada. Through the lens of ‘lived experience’, I will examine the interplay of identity, personal and communal histories, and the contemporary situation of my self and the First Nations communities I worked with, looking at how having ‘insider’ knowledge can be both useful and a handicap in fieldwork.     

马家浜文化区的地理景观

马家浜文化区的环境研究,以往都以1000年左右为尺度,即把马家浜文化作为一个基本时间单元来分析,所得结论是粗线条或大趋势性的。在马家浜文化研究近半个世纪的今天,我们已经有条件提取更多信息,变趋势性考察为过程性研究,进而描绘这一时期更加细微的演化曲线,构建人地关系景观。     

Sustainability of Highway Bridge Networks Under Seismic Hazard

In order to evaluate the seismic risk of transportation networks, it is necessary to develop a methodology that integrates the probabilities of occurrence of seismic events in a region, the vulnerability of the civil infrastructure, and the consequences of the seismic hazard to the society, environment, and economy. In this article, a framework for the time-variant seismic sustainability and risk assessment of highway bridge networks is presented. The sustainability of the network is quantified in terms of its social, environmental, and economic metrics. These include the expected downtime, expected energy waste and carbon dioxide emissions, and the expected loss. The methodology considers the probability of occurrence of a set of seismic scenarios that reflect the seismic activity of the region. The performance of network links is quantified based on individual bridge performance evaluated through fragility analyses. The sustainability and risk depend on the damage states of both the links and the bridges within the network following an earthquake scenario. The time-variation of the sustainability metrics and risk due to structural deterioration is identified. The approach is illustrated on a transportation network located in Alameda County, California.     

Experiment in landscape: the Norfolk excavations of Marietta Pallis

The paper considers the geographies of scientific knowledge produced around a pool dug at Long Gores, Hickling, Norfolk, England in 1953. Designed by ecologist and artist Marietta Pallis as a swimming pool and symbolic site, the pool also became a scientific experiment in landscape, through which Pallis pursued general ecological principles and specific theories on the landscape history and ecology of the Norfolk Broads. The digging of the pool coincided with the publication of research establishing the broads' artificial origin in medieval peat diggings. The paper begins by developing arguments concerning the cultural geographies of scientific knowledge. We then trace Pallis's presentation of the pool as equivalent for the broads in its origins and development, her discussion of the relationship between pool, marsh and North Sea, the connection between Pallis and local scientific culture, and the pool's place in a landscape of ecological succession. The paper concludes with further theoretical discussion, and reflection on the remains of Pallis and her reputation.     

Neolithic rock art in context: Landscape history and the transition to agriculture in Mediterranean Spain

Rock art is one of the most salient features of Neolithic societies in eastern Spain and an explicit form of landscape history. This paper summarizes current debates of Mediterranean rock art chronology and interpretation and explores the contextual differences in two areas of Neolithic settlement with rock art: the Canyoles Valley (Valencia) and the Alcoi Basin (Alicante). Large-scale survey of the Canyoles Valley resulted in a clearer understanding of agricultural land use during the Neolithic that contrasts with evidence from the Alcoi Basin. By analyzing Neolithic rock art in its archaeological context, we discuss the significance and limitations of rock art analysis for understanding and characterizing landscape histories and the transition to agriculture in the region.     

后现代主义园林设计语言的符号学研究

根据皮尔斯符号三分法和园林分类法,后现代主义园林的设计语言具有丰富的历史性、地域文化、大众文化图象符号和惯用性、表现性、叙事性、色彩象征符号。后现代主义园林不但强调历史文化、地域文化、大众文化的表达,还重视历史文脉的保护恢复。后现代主义园林的设计语言大部分都是从自己的本土文化中吸取的,形成了可理解性,可交流性、可对话性以及意义的可生成性的人性园林,努力恢复被现代主义园林割断的人文尺度。     

An uninhabited waste: transforming the Grand Prairie in nineteenth century Illinois, USA

Today the area once known as the Grand Prairie in the American Midwest is best known for its high agricultural productivity and monoculture. Little of the original prairie landscape that gave the region its name remains. Prior to white settlement, the region was perceived as swampy, dangerous, unhealthy and unfit for agriculture. This ‘uninhabited waste’ and ‘giant emporium of malaria’ embodied the type of landscapes settlers initially tried to avoid. Ultimately, perceptions of the Grand Prairie landscape as well as the physical landscape itself were altered by settlement and improving drainage technology. This paper aims to link changes in the way the central Illinois landscape was imagined and perceived, with the subsequent environmental transformation that resulted in the near total elimination of tallgrass prairie and the wholesale alteration of regional hydrology through channelization and agricultural drainage.
