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。     

人流联系和经济联系视角下区域城市关联比较——基于手机信令数据和企业关联数据的研究

手机信令数据所代表的人流联系与国内外研究常用的企业关联数据在测度城市关联存在何种差异,尚缺乏明确的研究。本文以江西省北部地区为研究对象,分别以手机信令数据、企业关联数据测度城市关联,比较了两种城市关联与城市之间空间距离、人口规模的关系,比较了两种城市关联网络的层级、结构、腹地。主要研究发现：人流联系不仅集中在城市周边地区,而且集中于较高等级城市之间;经济联系则主要集中在较高等级城市之间。人流联系、经济联系受到城市人口规模影响均较小。人流联系显著地符合幂函数空间衰减规律。手机信令数据和企业关联数据是两种不同的城市关联数据,但可互为补充,较为全面地反映城市关联。     

Smells like politics: planning and the inconvenient politics of intensive peri‐urban agriculture

Intensive farming is an increasing part of Australian agriculture, including in the multi‐functional landscapes at the edges of Australian cities. The example of intensive “broiler” poultry production reveals the tensions that arise when sites of hyper‐productivity conflict with social change in rural areas. Planning processes for intensive farming in the Australian state of Victoria are predicated on stability and consensus: on assumed static and uncontroversial ideas of agriculture, its place, and the primacy of agricultural productivity. Yet concerns about the industrialisation of agriculture are live political issues at the local level, especially in dynamic peri‐urban locations. This paper explores the emergence of a politics of place outside the bounds of planning consensus through an analysis of planning appeals and associated media relating to planning permits for intensive poultry developments in Victoria over 2011–2016. We highlight tensions that exist in relation to technical planning assessments and categorisations used to assert farming as the orthodox use of rural land, especially when new forms of farming look and feel demonstrably different. Using Mouffe's problematising of the negation of antagonism and Rancière's notion of the risks of a false consensus democracy, we argue that planning processes for intensive farming illustrate critical issues in participatory planning. While ostensibly post‐political decision‐making narrows the politics of place and food systems to decisions about policing the boundaries and buffer distances placed around intensive poultry developments, alternative representations of rural life persist. The certainty offered by code‐based planning does not negate the ongoing (if inconvenient) politics of intensive peri‐urban agriculture.     

Urban commons are more‐than‐property

Urban commons are characterised in the literature as collectively shared property in the city shaped by a context of scarce resources, population density, and the interaction of strangers. In the broader commons literature, commons appears as a verb, a noun, and a process made by practices of commoning—albeit still with a focus on property. In this paper, I argue that an understanding of urban commons as more‐than‐property is needed to recognise how present but elusive urban commons are. I use examples from interviews and observations conducted at a Women's Library to discuss how the access, use, benefit, care, responsibility, and ownership of this urban commons bring it into being through particular practices of commoning. By questioning current ways of defining urban commons, urban scholars gain a grounded understanding of the role of property, and other practices, in maintaining an urban commons over time.     

Working holiday makers in Australia: food security,climate change,and the backpacker tax

This commentary considers an often overlooked contribution to food security in Australia—the labour of working holiday makers. Their ability to act as a flexible and mobile temporary workforce is essential to the maintenance of the Australian agricultural industry. Previously, no tax was payable on income below $18,200, but a 2015 proposal to increase their tax rate sparked a vigorous political debate and so revealed their importance to the agricultural industry. A decline in backpacker numbers would cause agriculture to shrink to cope with smaller workforces. But the effects of climate change are expected to further shrink agricultural areas as extreme events and hotter temperatures impact crops, livestock, and the productivity of agricultural workers. Issues that appear manageable when viewed in isolation, such as increases in the tax rate on working holiday makers, become more problematic when viewed in conjunction with other impacts affecting agriculture. Thus, the ‘backpacker tax’ risks making food security harder to maintain at a time when Australia's agricultural system is already vulnerable to climate change.     

Conflicts Over Trees and Waves on Siberut Island

ABSTRACT The paper describes some recent developments with respect to logging operations and the tourist industry on the island of Siberut (West Sumatra, Indonesia). It discusses these developments from the perspective of the notions of equitable access and benefit sharing and prior informed consent. These are often referred to as basic principles in dealing with external intervention within the territory of indigenous peoples. After the initial logging boom during the 1970s and 1980s about half of the island was declared a nature reserve in the early 1990s. All logging operations were terminated. Backpack tourism started to develop more or less simultaneously, stimulated by the lure of a Stone Age culture on a tropical paradise island. This contributed greatly to the efforts to safeguard the island's rich biodiversity. Recently, however, a new form of logging started on the island, with a university as concession holder. But also a new kind of tourism discovered Siberut: its waves are supposed to be of excellent quality and allow for first‐class surfing. As a result of regional autonomy and the process of democratisation in Indonesia, the local people are not willing to accept these new forms of resource use without at least sharing in their benefits. This paper is based on extensive periods of fieldwork on Siberut over the past twenty years.     

Home divided,home reconstructed: children in rural–urban migration in contemporary China

This article is centred on the geographies of Chinese children in contemporary China – an area which has been problematically overlooked in geographical literature on childhood. In employing unique mobile research methods by tracking migrant children through the migration cycle, the author conducted an extensive ethnographic study of rural migrant children aged 8–17 in China. The article explores rural children's everyday lived experience of migration and how migrant children negotiate and articulate home and belonging while on the move. The study demonstrates the dynamic environment that migrant children inhabit, the fluid, contextual and mobile nature of their life in rural migrant households, their migrancy and their active involvement in homemaking.     

Conceptions of place: approaching space,children and physical activity

In this paper, we argue that place mapping is useful for approaching children's conception of place and that this is of relevance when designing physical activity interventions. We contend that socio-material factors influence children's perception and use of places, and are crucial to understand in relation to their use of local neighbourhoods for physical activity. A place mapping of children's understandings and everyday use of their local neighbourhood in suburban Copenhagen was conducted with a fifth grade elementary school class. The mapping and subsequent analysis resulted in three categories of relevance to children's conceptions of place; located social experiences, experiences of the unknown, and children's contested spaces. We argue that such knowledge can provide useful information in the development and evaluation of activities that promote physical activity in urban spaces.

Knowledge Production,Urban Locations and the Importance of Local Networks

This paper analyses the relationship between knowledge production and urban locations in industrial design, a knowledge-intensive business service (KIBS). KIBS concentrate in urban locations. This is often explained by the co-location of client firms and market access in large cities. Recent research on knowledge production, however, reveals that knowledge productive networks are significant for both the competitiveness and location of KIBS. Thus, to understand the urban location of industrial design, it is important to analyse how knowledge production is organized within the industry. Industrial design is concentrated in urban locations, but most of its clients are located elsewhere. Hence, it seems that industrial design firms concentrate in urban locations mainly because their knowledge networks include specific types of formal and informal local social networks.
