ABSTRACT Increasing attention has been paid to the analysis of street greenery using the Green View Index (GVI). Current methods of vegetation extraction are not suitable for processing large amounts of data. This study introduces Visible Difference Vegetation Index (VDVI) to process Baidu Map panoramic static images which is relatively convenient for GVI calculation. The method is used to analyse the spatial distribution of street greenery in Guangzhou city in China. The results show that: (1) The spatial distribution of GVI values in Guangzhou show obvious agglomeration. (2) The average level and evenness of street greenery distribution is analysed. Tianhe and Yuexiu districts had high levels of evenly distributed street greenery; Liwan, Haizhu, Huangpu, and Panyu districts had good levels of street greenery but uneven distributions; Baiyun and Nansha had low levels of street greenery. (3)There is a significant correlation between road grade, house price, building age, land use and GVI values, which reveals the driving factors of GVI value distribution in Guangzhou. The GVI calculation method in this method is relatively convenient and accurate. GVI can be a new evaluation tool for street greenery in urban planning, additionally used as an index for urban environmental research.
利用绿色景观指数(GVI)对街道绿化进行分析越来越受到人们的关注。现有的植被提取方法不适合处理大量数据。本研究引入可视植被差异指数(VDVI)对百度地图全景静态图像进行处理,相对方便GVI的计算。利用该方法对广州市街道绿化的空间分布进行了分析。结果表明:(1)广州市GVI值的空间分布具有明显的集聚性。(2)分析了街道绿化分布的平均水平和均匀度。天河区和越秀区街道绿化水平较高,分布均匀;荔湾、海珠区、黄埔区和番禺区街道绿化水平较好,但分布不均;白云和南沙的街道绿化水平较低。(3)道路等级、房价、楼龄、土地利用与GVI值存在显著相关,揭示了广州市GVI值分布的驱动因素。该方法的GVI计算方法相对方便、准确。GVI可作为城市规划中街道绿化评价的新工具,也可作为城市环境研究的指标。

ABSTRACT Rural–urban migration is considered one of the main reasons for rural decline, but the links between out-migration and rural settlement change are not well understood. This study explores the microimpact of out-migration on rural livelihoods and housing strategies in Southwest China. It is based on the results of a survey with 411 respondents. A cluster analysis revealed five distinct types of rural households considering their ways of migration and livelihoods. Only one of them depends on agriculture, whereas the others are characterized by different kinds of migration and off-farm activities. This study provides in-depth insights into the microimpact, thus informing future rural development policy.
摘要城乡人口迁移被认为是农村人口减少的主要原因之一,但人们对农村人口外迁与农村定居变化之间的关系却知之甚少。本研究探讨了外迁对西南地区农村生计和住房策略的微观影响。这是根据对411名受访者的调查结果得出的。聚类分析揭示了五种不同类型的农村家庭,考虑到他们的迁移和生计方式。其中只有一种依赖农业,而其他的则以不同类型的迁移和非农活动为特征。本研究提供了对微观影响的深入见解,从而为未来的农村发展政策提供信息。

ABSTRACT Suburbanization is the most significant process involved in shaping the socio-spatial structure of many western European and post-Socialist cities. In Prague, suburbanization began in the mid-1990s. In contrast with most studies, we consider the suburbs not as a final residential destination but as a place that people leave as a result of life-phase changes. For example, families who moved to the suburbs in the mid-1990s and early 2000s, and are now empty-nest households, may wish to move away. In an attempt to analyse future residential mobility and strategies for later-life suburban households in Czechia, we conducted a questionnaire survey in two suburban municipalities (n = 177). Respondents were aware that as they aged, their current residences and residential environments were likely to become less suitable. Nevertheless, most of our respondents were “stayers” and employed various assimilative coping strategies to adapt their homes, rather than moving or leaving the suburbs. It is suggested that a greater emphasis be placed on the promotion of barrier-free housing solutions and the use of innovative technologies.
郊区化是塑造许多西欧和后社会主义城市社会空间结构的最重要过程。在布拉格,郊区化始于20世纪90年代中期。与大多数研究相反,我们认为郊区不是最终的居住目的地,而是人们因生活阶段变化而离开的地方。例如,在20世纪90年代中期和21世纪初搬到郊区的家庭,现在是空巢家庭,可能希望搬走。为了分析捷克郊区老年家庭未来的居住流动性和策略,我们在两个郊区市镇(n = 177)进行了问卷调查。受访者意识到,随着年龄的增长,他们目前的住所和居住环境可能会变得不太适合。然而,我们的大多数受访者是“留居者”,他们采用各种同化应对策略来适应他们的家园,而不是搬离或离开郊区。建议更加强调促进无障碍住房解决办法和使用创新技术。

ABSTRACT Agricultural land use and population density have been increasing around the world. Determining if physical geography is a driving factor of historical change on a larger scale has received little research interest in the past outside local-scale case studies. The aim of this study was to model historical agricultural development and population density throughout Denmark using geographically weighted regression with environmental variables and data for parishes from 1860 to 1890. We analysed rye production, sheep count, and population density on the national scale. The incorporated variables were selected to represent aspects of soil, climate, and topography. Models for rye and sheep had high explanatory power (global R2: between 0.60 and 0.68) for both time periods whereas the model for population density had low explanatory power (global R2: 0.09 in 1860 and 0.25 in 1890). The results indicate that historical development in agricultural geography can be explained using physical geography. However, population density is more complex due to influences of industrialization, culture and scalar structure. This questions the classical understanding that soil quality is a strong determinant of population density on its own in Denmark. We instead argue that soil quality has a dynamic multidirectional interplay with human and agricultural activity.
世界各地的农业用地和人口密度都在不断增加。在过去,除了局部尺度的案例研究之外,确定自然地理是否是更大尺度上历史变化的驱动因素的研究兴趣很少。本研究的目的是利用地理加权回归,结合环境变量和1860年至1890年的教区数据,对整个丹麦的历史农业发展和人口密度进行建模。我们在全国范围内分析了黑麦产量、绵羊数和人口密度。合并变量被选择来代表土壤、气候和地形的各个方面。黑麦和绵羊模型在两个时间段具有较高的解释能力(总体R2为0.60 ~ 0.68),而种群密度模型的解释能力较低(总体R2为1860年的0.09和1890年的0.25)。结果表明,农业地理学的历史发展可以用自然地理学来解释。然而,由于工业化、文化和标量结构的影响,人口密度更为复杂。这对传统的理解提出了质疑,即土壤质量是丹麦人口密度的一个重要决定因素。相反,我们认为土壤质量与人类和农业活动具有动态的多向相互作用。

ABSTRACT Social integration plays a key role in the quality of life of the elderly who move from a rural to an urban area (land-lost elderly), and successful urban integration is known to develop harmony and age-friendly society. Very few studies are concerned with incorporating subjective as well as objective elements into measuring social integration levels of land-lost elderly. In this study, we measured and compared social integration levels between different neighbourhoods of land-lost elderly. We found land-lost elderly in the public housing neighbourhoods, and compared to the commodity housing elderly, they have a higher level of social integration in three aspects: having positive attitudes towards urban life, having high participation rate in activities, and participating activities with neighbours. This is because the elderly living in public housing have neighbours from similar socio-demographic groups and have more social interactions. In addition, the built environments are closely related to social integration levels of the elderly in both neighbourhoods, but effects in the two neighbourhoods present a few differences; the improvement in social environments can greatly facilitate social integration of elderly living in public and commodity housing neighbourhoods, especially for improvement in social contacts with neighbours.
社会融合对从农村迁移到城市的老年人(失地老年人)的生活质量起着关键作用,而成功的城市融合被认为是构建和谐和老年人友好型社会的关键。很少有研究涉及将主观和客观因素纳入衡量失地老年人的社会融合程度。在这项研究中,我们测量和比较了失地老年人不同社区之间的社会整合水平。我们发现,与商品住房老年人相比,公共住房社区的失地老年人在三个方面的社会融合水平更高:对城市生活的积极态度,对活动的高参与率,以及与邻居一起参与活动。这是因为住在公共房屋的长者有来自相似社会人口群体的邻居,有更多的社会交往。此外,建成环境与两个社区的老年人社会融合水平密切相关,但在两个社区的影响存在一些差异;社会环境的改善可以极大地促进居住在公共住房和商品住房社区的老年人融入社会,特别是改善与邻居的社会联系。

ABSTRACT Following the expansion of NATO in 2004 and the EU in 2007, Romania has become the Eastern frontier of these structures, which lends Romanian borders a strategic role. The territorial development of a border area is influenced by the political, economic, socio-cultural, demographic characteristics of the neighbouring countries sharing the same border. The border areas of Romania include 898 Local Administrative Units (LAU), of which 88 are urban. Romania has a border line (2956.4 km, of which 63.5% is non-European Union border) with the following countries: Bulgaria, the Republic of Moldova, Serbia, Ukraine, Hungary. The current paper seeks to identify the territorial disparities in the urban development of the Romanian border areas by 3 secondary indexes in order to reflect the main territorial development aspects: competitiveness (TComp), cohesion (TCoh), and sustainability (TSust). Lastly, the authors were able to establish the Index of Territorial Development (ITD) revealing the levels of territorial development. Assessing the competitiveness, cohesion and sustainability levels of urban centres is a useful and necessary stage, done through this study, for establishing those socio-economic fields, those towns and border sectors which are less developed, requiring attention from the regional, national and local administrations, reflected in investments.
随着2004年北约和2007年欧盟的扩张,罗马尼亚已经成为这些组织的东部边界,这使得罗马尼亚的边界具有战略意义。边界地区的领土发展受到共享同一边界的邻国的政治、经济、社会文化和人口特征的影响。罗马尼亚的边境地区包括898个地方行政单位,其中88个是城市。罗马尼亚与以下国家有一条边界线(2956.4公里,其中63.5%为非欧盟边界):保加利亚、摩尔多瓦共和国、塞尔维亚、乌克兰、匈牙利。本文试图通过三个二级指标来确定罗马尼亚边境地区城市发展的地域差异,以反映主要的地域发展方面:竞争力(TComp)、凝聚力(TCoh)和可持续性(TSust)。最后,建立了反映区域发展水平的区域发展指数(ITD)。通过这项研究,评估城市中心的竞争力、凝聚力和可持续性水平是建立需要区域、国家和地方行政当局注意的较不发达的社会经济领域、城镇和边境部门的有益和必要阶段,这反映在投资中。

ABSTRACT This research note reviews recent literature on the vulnerability of critical infrastructures caused by climate change with a focus on the Nordic countries. We integrate literature from three research areas: the role of critical infrastructures in the functioning of society, infrastructural vulnerabilities, and the long-term impacts of climate change. Focusing on climate change adaptation in the Nordic countries as a pivotal case, we discuss the mutually constitutive interrelationships between these three areas. The studies reviewed bring together social science and humanities research on infrastructure systems, their vulnerabilities, and climate change. By highlighting interdisciplinary perspectives on infrastructures, climate change, and societal security, this research note discusses a Nordic model of infrastructure provision and links the Nordic debate to a burgeoning European discussion on the role of the social sciences and humanities in addressing societal challenges related to climate change and the role of infrastructures in providing welfare.
本研究报告回顾了最近关于气候变化导致的关键基础设施脆弱性的文献,重点是北欧国家。我们整合了三个研究领域的文献:关键基础设施在社会功能中的作用、基础设施脆弱性和气候变化的长期影响。我们以北欧国家的气候变化适应为重点,讨论了这三个领域之间相互构成的相互关系。这些研究汇集了社会科学和人文科学对基础设施系统及其脆弱性和气候变化的研究。通过强调基础设施、气候变化和社会安全的跨学科观点,本研究报告讨论了北欧的基础设施提供模式,并将北欧的辩论与欧洲新兴的关于社会科学和人文科学在应对与气候变化相关的社会挑战以及基础设施在提供福利方面的作用的讨论联系起来。

ABSTRACT To what extent territorial cohesion is achieved or not, due to the EU Cohesion Policy, national regional policies, or globalization forces, is debated. This paper aims at discussing territorial cohesion at a NUTS 3 level in Denmark, Finland, Norway and Sweden for 2007 and 2017 by using the Territorial Cohesion Development Index. The findings indicate a) that bigger cities and highly urbanized regions in Denmark, Finland and Sweden perform very well in the Territorial Cohesion Development Index, while non-core and peripheral regions fell further behind; and b) all Norwegian regions and the Åland Islands have high scores in the Territorial Cohesion Development Index. The findings indicate a need to resuscitate the national regional policies in Denmark, Finland and Sweden to counteract the increasing gap between the capital region and the rest of the regions.
由于欧盟凝聚力政策、国家区域政策或全球化力量的影响,在何种程度上实现了领土凝聚力。本文旨在利用领土凝聚力发展指数探讨2007年和2017年丹麦、芬兰、挪威和瑞典在NUTS 3水平上的领土凝聚力。研究结果表明:①丹麦、芬兰和瑞典的大城市和高度城市化地区在区域凝聚力发展指数上表现良好,而非核心和外围地区则进一步落后;b)所有挪威地区和Åland岛屿在领土凝聚力发展指数中得分很高。研究结果表明,需要恢复丹麦、芬兰和瑞典的国家区域政策,以抵消首都地区与其他地区之间日益扩大的差距。

ABSTRACT Tourism and natural resources are rapidly changing in the Arctic. Human activities and climate change are transforming natural landscapes and affecting populations of wildlife, while remote Arctic destinations that were previously regarded as inaccessible and unattractive are being engulfed by the global increase in tourism. In parallel with these developments, the concept and practice of “sustainable tourism” is gaining weight. Connecting these two trends raises multiple questions, including how tourism affects natural resources in the Arctic and whether sustainable Arctic tourism is possible. We conduct a systematic review of scientific publications connecting tourism and natural resources in the Arctic in order to shed light on the environmental dimensions of sustainable tourism. Based on our review, we highlight the multidirectional relationship between tourism and natural resources, and we use southern Greenland as a concrete example of an Arctic destination to which we tie our discussion of “sustainable tourism” in both theory and practice. We conclude that framing sustainable tourism as a relative and comparative concept specific to the time, place and type of tourism activity, rather than as a set of general and ideal criteria, might be more applicable and meaningful in research and as a development strategy for tourism destinations.
北极的旅游业和自然资源正在迅速变化。人类活动和气候变化正在改变自然景观,影响野生动物种群,而以前被认为难以进入和没有吸引力的偏远北极目的地正在被全球旅游业的增长所吞没。在这些发展的同时,“可持续旅游”的概念和实践也越来越受到重视。将这两种趋势联系起来提出了多个问题,包括旅游业如何影响北极的自然资源,以及可持续的北极旅游是否可能。我们对有关北极旅游和自然资源的科学出版物进行了系统审查,以阐明可持续旅游的环境层面。在回顾的基础上,我们强调了旅游与自然资源之间的多向关系,并以南格陵兰岛为北极目的地的具体例子,将我们对“可持续旅游”的理论和实践讨论联系起来。我们的结论是,将可持续旅游作为一个特定于时间、地点和旅游活动类型的相对和比较概念,而不是作为一套一般和理想的标准,可能在研究和旅游目的地的发展战略中更适用和有意义。
