Narratives of Spatial Division： The Role of Social Memory in Shaping Urban Space in Belfast

The paper examines the role of shared spaces in divided cities in promoting future sustainable communities and spaces described as inclusive to all. It addresses the current challenges that prevent such inclusiveness and suggests future trends of its development to be of benefit to the wider city community. It explains how spaces in divided cities are carved up into perceived ownerships and territorialized areas, which increases tension on the shared space between territories; the control of which can often lead to inter-community disputes. The paper reports that common shared space in-between conflicting communities takes on increased importance since the nature of the conflict places emphasis on communities＇ confidence, politically and socially, while also highlighting the necessity for confidence in inclusion and feeling secure in the public domain. In order to achieve sustainable environments, strategies to promote shared spaces require further focus on the significance of everyday dynamics as essential aspects for future integration and conflict resolution.     

Research on the Relationship Between Multidimensional Characteristics of Blue-Green Spaces and Mental Health of Older Adults

According to the Theory of Justice, the characteristics of vulnerable groups should be considered in realizing the mental health benefits of blue-green spaces, so as to promote substantive equity and welfare in cities. The unclear relationship between the blue-green space indicator system and the mental health of older adults at both the quantitative and qualitative levels has hindered the development of spatial justice and health equity in cities. Based on the theories of stress reduction and a...     

全球城市与社会极化研究：基于北上广的实证分析（英文）

Globalization can promote the flow of production factors across countries and regions.Developing "global cities" in China is conducive to enhancing China’s international competitiveness and participation in the world’s economic activities.Relevant theories reveal that globalization is of great significance to urban socio-spatial restructuring,and the social polarization or professionalization issues brought by "global cities" have been controversial.Based on the data from the statistical yearbooks of Beijing,Shanghai,and Guangzhou,this study tries to test the global city hypothesis through the analysis on these three "global cities" in China.The study finds that Beijing and Shanghai have shown certain social polarization characteristics in the process of social differentiation,while Guangzhou has not.The results can provide scientific support for the formulation of urban management and household registration policies in China.     

Underground space planning in Helsinki

This paper gives insight into the use of underground space in Helsinki,Finland.The city has an underground master plan(UMP) for its whole municipal area,not only for certain parts of the city.Further,the decision-making history of the UMP is described step-by-step.Some examples of underground space use in other cities are also given.The focus of this paper is on the sustainability issues related to urban underground space use,including its contribution to an environmentally sustainable and aesthetically acceptable landscape,anticipated structural longevity and maintaining the opportunity for urban development by future generations.Underground planning enhances overall safety and economy efficiency.The need for underground space use in city areas has grown rapidly since the 21 st century;at the same time,the necessity to control construction work has also increased.The UMP of Helsinki reserves designated space for public and private utilities in various underground areas of bedrock over the long term.The plan also provides the framework for managing and controlling the city's underground construction work and allows suitable locations to be allocated for underground facilities.Tampere,the third most populated city in Finland and the biggest inland city in the Nordic countries,is also a good example of a city that is taking steps to utilise underground resources.Oulu,the capital city of northern Finland,has also started to ‘go underground'.An example of the possibility to combine two cities by an 80-km subsea tunnel is also discussed.A new fixed link would generate huge potential for the capital areas of Finland and Estonia to become a real Helsinki-Tallinn twin city.     

Research on New Urban Area Planning Based on TOD Mode:A Study on Binhu New District of Hefei City

As an urban development mode,the TOD (Transit-oriented Development) mode,targeted at energy-saving and based on the public transportation system,has positive significance for solving problems like disordered urban sprawl and traffic congestion in Chinese cities.This article takes Binhu New District of Hefei as an example to illustrate the practice of the TOD mode in the urban design of large and medium-sized cities.The paper analyzes the relationship between the new district,central urban area,and public transportation development,and puts forward that the TOD mode is suitable for Bihu New District.It states that the TOD mode can be realized through methods such as the building of a "double-rapid" comprehensive public transportation network,the setting up of decentralized-compact urban clusters and TOD communities,the mixevd land-use,as well as the scenery design with complete walking space.The paper also proposes that certain flexible methods can be adopted in order to promote the TOD mode,including making full use of bus transit when rail transit is lacked,setting up TOD communities surrounding the transport hubs,etc.

Underground space planning in Helsinki

This paper gives insight into the use of underground space in Helsinki, Finland. The city has an undergroundmaster plan （UMP） for its whole municipal area, not only for certain parts of the city. Further, the decision-making history of the UMP is described step-by-step. Some examples of underground space usein other cities are also given. The focus of this paper is on the sustainability issues related to urbanunderground space use, including its contribution to an environmentally sustainable and aestheticallyacceptable landscape, anticipated structural longevity and maintaining the opportunity for urbandevelopment by future generations. Underground planning enhances overall safety and economy efficiency.The need for underground space use in city areas has grown rapidly since the 21st century; at thesame time, the necessity to control construction work has also increased. The UMP of Helsinki reservesdesignated space for public and private utilities in various underground areas of bedrock over the longterm. The plan also provides the framework for managing and controlling the city＇s underground constructionwork and allows suitable locations to be allocated for underground facilities. Tampere, the thirdmost populated city in Finland and the biggest inland city in the Nordic countries, is also a good exampleof a city that is taking steps to utilise underground resources. Oulu, the capital city of northern Finland,has also started to ＇go underground＇. An example of the possibility to combine two cities by an 80-kmsubsea tunnel is also discussed. A new fixed link would generate huge potential for the capital areasof Finland and Estonia to become a real Helsinki-Tallinn twin city.

The Historical Evolution of Chinese Urban Morphology

China has had a long urban experience. The existence oftowns in China can be dated to 2600 BC, and the pattern of urbanmorphology were essentially different from those in other majorcultural regions, which represents one of the major forms of urbangrowth of the world. This paper describes the characteristics andhistorical development of Chinese urban morphology. The centrallocation of political and administrative buildings, a grid-iron streetpattern, symmetrical layout and axis are the most important charac-teristics of Chinese traditional cities, which reflected the distinctivepolitical and economic system and cultural traditions of China. Polit-ical forces play a key role in shaping this urban pattern. The histori-cal development of Chinese urban morphology experienced fourphases: the walled city (770 BC——AD 906), the open city (618——1840), the colonial city (1840——1949), and the modern city(1949——1985). Each of these phases has its distinct characteris-tics and different planning philosophies reflecting the current na-tional political and economic development. The central feature of ur-ban development in China is that the process has been controlledto a large extent by the highly centralized government. After 1949,Chinese cities experienced a fundamental transformation in their in-ternal structure and morphology which reflect the communist idealsin urban planning. The key aims of urban planning in communistChina is to establish a highly productive and convenient living envi-ronment, and to reduce the gaps between city and countryside in or-der to achieve a new type of socialist city with 'classless' or 'uni-form socio-economic characteristic.     

Rise,Growth and Evolution of the Chinese Urban System

The paper explores the rise,historical growth and evolution of the Chinese urban sys-tem in its spatial context and the implication of these characteristics for the spatial distri-bution of cities and economic activity,the pattern of interaction,and the processes ofgrowth and change.The growth of modern city links with its development history,geographical condi-tions,economic basis and political systems of a country.There has been rapidurbanization in China during the last several decades,as in other developing countries.The purpose of this paper is to review the rise.growth,evolution and development ofChinese urban system in the time-spatial context.First,when did the initial cities emerge?Second,when did the Chinese urban system rise? Third,how did the urban system growand evolute?

旅游业缩小城乡差距

UN-Habitat is embarking on an exciting programme to implement an often-overlooked part of its mandate-to promote city tourism around the world. The idea is that visitors to famous and not so famous towns and cities see how other people live, especially the poorest of the poor so that they can benefit from tourism as a source of income and enable them to meet their shelter needs. The Istanbul Declaration and Habitat Agenda gives UN-Habitat a mandate that takes in not just cities and towns per se, but the peri-urban zones that skirt them, and urban-rural linkages that can be of considerable benefit to countries proud to draw on the development potentials of tourism. Well-managed tourism can certainly help strengthen the positive links between urban and rural areas. This article gives some examples of traditional and newly developed tourism.     

Controversy Over China''''s Traditional Commercial-Streets

In recent years,a great number of traditional commercial streets has reappeared in China.The first attempt wasthe renovation of the kiu-Li-Chang street in Beijing.The renovation of the Liu-Li-Chang street in Beijing was proposed in 1978,with the first stage of the projectstarted in October,1980.It included the reconstruction of a 500 metre-length of street and 54 stores on both sideswith a floor space of 34 thousand square metres.The whole project was basically completed in the short period of afew years and has won acclaims from architects and planners at home and abroad,though arguments still exist.Soonafterwards,many cities followed suit with such influential ones as the traditional culture street in Tianjin,theCheng-Huang-Miao Temple market in Hefei and the Fu-Zi-Miao Temple market in Nanjing,etc.Traditionalcommercial streets have been set up not only in big cities.but also in some medium-sized and small cities.They are,of course,smaller in size and generally simpler.Some of the traditional commercial streets have been quite successful,while some have not produced good results.There has been a great argument among the Chinese planners and archi-tects on issues related to the traditional commercial street.Ⅰ,herewith,would like to express my view.

The Avenue of Sphinxes： Restoration of a Legend

The redevelopment of historic cities is often challenged by intricate--and in many cases contradictory--missions. From one side, there is the urge to comprehensively preserve cultural resources. At the same time, opportunities of economic growth should be made available and needs of contemporary living maintained and nourished. The main aim of this paper is to reconcile probable incompatibilities between such missions through promoting ＂sensitive＂ redevelopment approaches in historic cities. The paper focuses on the city of Luxor, Egypt with its immensely capturing yet quite undermined legend： the Avenue of Sphinxes. In Luxor, the injection of nonintrusive interventions presents itself as a highly potential candidate in protecting and enhancing the experience of the avenue while meeting contemporary needs of living. Adopting less sensitive development approaches can lead the quality of experiencing the whole city to be worsened for the increasing numbers of tourists and locals.     

“当前现有的全球化”所造成的危害

The ‘really existing globalization‘, which is used to refer to the type of globalization we see today, is viewed by the author to pose great dangers to life in cities by increasing poverty and gap between the rich and the poor,handicapping developing cities through specialization of functions, advocating marketization of housing and privatization of public services which are harmful to the urban poor, prioritizing profit instead of quality in environmental management and magnifying the danger of terrorism to cities. However, this is not the only form of globalization possible.     

城市收缩与人口老龄化——基于中国138个县级市的实证

Urban shrinkage is a world-wide phenomenon characterized by population loss in a short period of time.During this process,the decrease of the younger generation will further accelerate the demographic aging process through lowering birth rates.Although many studies have qualitatively addressed that demographic aging could be both a result and cause of urban shrinkage,empirical studies to examine their interrelations are lacking.This paper aims to examine their interrelationships by proposing an integrated model which covers the paths,effects,and interrelationships between shrinking cities and demographic aging in economic,spatial,and social dimensions.Based on the data from 138 county-level cities in China,partial least-square method is used for structural equation modeling(PLS-SEM).The results show that two indirect influence paths exist between shrinking cities and the demographic aging process.First,urban shrinkage has an indirect interaction with the demographic aging process via social and economic factors(path:shrinking cities←→society←→economy←→aging process).Second,urban shrinkage is also indirectly interrelated with the demographic aging process in spatial factors(path:shrinking cities←→space←→aging process).To deal with the double challenges of urban shrinkage and demographic aging,planning policies should integrate with policies in socio-economic and spatial aspects.
