目前GIS在旅游研究中的应用缺乏系统回顾。通过对CNKI的中文核心期刊数据库、Web of Science核心合集外文数据库进行主题检索,借助Note Express3. 2和Cite Space V软件对选取的688篇论文进行了回顾和反思。研究发现:GIS在旅游研究中的应用领域主要包括旅游信息化、旅游空间结构、旅游规划与开发、生态旅游评价、旅游预警、旅游交通、旅游制图、旅游大数据采集与分析等8个方面,体现了旅游信息检索、旅游空间分析、旅游辅助决策、旅游信息输出、旅游应急处理等5大功能。但现阶段的成果存在采用的研究方法欠科学、重点研究领域有待加强、研究对象相对局限、重复性研究多等问题,因此今后应加强GIS技术与多种方法的集成与融合,更好地服务于旅游研究。  相似文献

This article discusses the concept of public space management and its evolution in a context of wider changes to urban governance. Public space management is taken as a sphere of urban governance in which conflicting societal demands on, and aspirations for, public space are interpreted through a set of processes and practices. Four interlinked dimensions for public space management are proposed: the co-ordination of interventions; the regulation of uses and conflicts between uses; the definition and deployment of maintenance routines; and investment in public spaces and their services. Within this conceptual framework, the paper looks at recent changes in public space management in England to suggest the emergence of alternative models of management. These are based on the roles ascribed to the state, to private agents and to user organisations, and on different approaches to dealing with the four management dimensions. Although the discussion shows that these models are more than just abstract formulations, and have been used to deal with a variety of public space problems, an important purpose for the paper is to provide an analytical framework through which to examine emergent practices in the management of public space and their potential consequences.  相似文献

在人本主义地理学框架下,对城市社会空间结构的分类研究成为必然。以流动人口空间结构为主题,总结了城市化一空间的二元分析框架。在此基础上重点构建了流动人口空间结构体系,对流动人口区位空间、行为空间和感应空间的涵义、特征、功能等进行解析。认为流动人口空间是在城市空间基底上叠加的具有流动人口特质的空间形态,是一种再造的空间。提出流动人口收入水平及行为活动的多少是影响流动人口空间关系的主要因素。  相似文献

Urban public spaces are important areas for leisure, recreation and physical activity and therefore contribute to the quality of life in cities. In particular, for adolescents they provide important spaces to meet with their peers, away from parental or school control. In many cities worldwide, public spaces have undergone severe developmental processes, and often a withdrawal from public space is noted. With regard to the opportunities those spaces provide for adolescents, it is necessary to investigate their current meaning for adolescents in a leisure context. In this article, qualitative research methods were used to investigate factors affecting adolescents’ use of public spaces in Vienna, Austria. In total 45 adolescents were interviewed. Results show that public open spaces are not regarded as important leisure spaces, and data reveal a strong retreat to private areas for leisure purposes. Perceived insecurities and fears support these processes and often result in avoidance of public spaces but also the wish for more control by authorities.  相似文献

Creating sense of community: The role of public space   总被引:3,自引:0,他引:3  
A strong sense of community has been associated with improved wellbeing, increased feelings of safety and security, participation in community affairs and civic responsibility. Although interest in how the broader built environment influences sense of community is gaining momentum, there is a dearth of empirical research examining the association between sense of community and the quality of public space. This study investigates the relationship between four public spaces – Public Open Space (POS), community centres, schools and shops – and sense of community in residents of new housing developments in the Perth metropolitan area, Western Australia. Data was obtained from a cross-sectional survey (n = 911), a POS audit, and Geographical Information Systems, and analysed using linear regression. The perceived quality of neighbourhood POS and shops was significantly and positively associated with sense of community. This relationship appears to be unaffected by how frequently people use these spaces. High quality public spaces may be important settings for enhancing sense of community within residents of new housing developments.  相似文献

本文旨在探讨如何使较大生态空间斑块形成闭合区域,在空间属性上保持相对的完整性和单一性,并加以有效保护,使生态空间真正成为城市发展的绿色屏障。从现有文献和同江市"多规合一"实践看,由于历史遗留、追逐利益和监管不力等诸多因素,生态空间甚至核心区域内有耕地和较大面积的生活聚居区挤占生态空间,导致环境质量下降。可通过退耕还林还草工程、迁出生态空间居民工程和加强生物多样性保护工程等路径实现生态空间完整性。与此同时,采取加大对生态空间的保护力度、提高公众对生态空间完整性的认识、建立科学的生态补偿机制及加强中俄生态保护合作等措施加以保护。  相似文献

Numerous undeveloped and ecologically diverse tracts of land within urban communities in the United States are presently being utilized for a variety of unsupervised recreational activities. The present use and perceived value of residual open spaces adjacent to the Palisades to residents of four communities in northeastern New Jersey was assessed. The results of our survey suggest that parks and open space represent a city service that is not as highly valued as other more visible services, that respondents desire a diversity of recreational experiences, that existing parks and open space provide a narrow range of recreational benefits to users, that benefits of existing parks extend primarily to the provision of active pursuits, and that undeveloped residual open spaces are valued for and provide opportunities for a variety of passive pursuits.Residual open spaces are a resource that contributes towards meeting the aesthetic and recreational needs of city residents. Failure by planners and decision-makers to recognize the value and utility of such tracts of land may result in their destruction and in the loss of a resource which provides a range of recreational opportunities that is not adequately provided by formal parks and open spaces.Paper of the Journal Series, New Jersey Agricultural Experiment Station, Cook College, Rutgers University, New Brunswick, New Jersey.This work was performed as a part of NJAES Project No. 17501, Urban Forestry: Planning and Management of Residual Open Space, supported by the New Jersey Agricultural Experiment Station and by a grant from the Consortium for Environmental Forestry Studies sponsored by the U.S. Department of Agriculture, Forest Service, Northeast Forest Experiment Station.  相似文献

It is widely acknowledged that marine spatial planning (MSP) should be responsive to the dynamism of the marine environment and the relatively tenuous human relationship with the sea. However, MSP remains conceptualised within rationalistic terms that limit this potential. This article places MSP within the context of spatial theory that holds greater promise for developing more progressive practice. Firstly, the interrelation of MSP with current notions of soft space (less formal, cross-cutting spatialities) is explored, suggesting that MSP is expressing some of the geographical and institutional freedoms of soft space, and may contribute new insights to this concept. Secondly, a progressive framework is developed that builds upon soft space principles. This draws in, on the one hand, underlying relational understandings of space, and on the other hand, insights from marine contexts. This leads to a picture of marine space-being-planned as lively space, expressing, amongst other things, the sea’s materiality. This concept is illustrated through an application of the framework to a strategic MSP exercise for the Baltic Sea region. Finally, it is suggested that MSP itself should be reconceptualised as immersed into this spatial ontology, with the agents and practices of planning taking their place within the wider assemblage of marine actants and relations.  相似文献
