In many highly dense urban environments, the urgent needs of residents for increasing green space, improving the quality of the community environment and reconstructing the relationships among residents have given birth to the new space type of community gardens. However, China still lacks this relevant experience. In contrast, New York City’s community gardens had a relatively early start, and they now have rich experience in space construction, operation and maintenance. Given their level of experience, they can be used as references for the development of community gardens in China. This paper adopts a bibliometric research method, identifies 201 periodical literature sources published between 2000 and 2020 from the core library of the Web of Science as the object of study, and finally assesses the research hotspot for transferring from macro-research to space-type construction method, social impact, and so on, through CiteSpace software analysis. By virtue of the research process analysis and the results of field surveys and interviews, this paper probes the development status of space construction and social organization construction of the community gardens in New York City, and summarizes that area’s effective experience of development. Based on the current development situation of China’s community gardens, it is proposed that the development of community gardens should be directed by ensuring the land for development, giving full play to social benefits, and mobilizing social organizations, so as to effectively realize urban space construction and social governance. 相似文献

ABSTRACT. For centuries, a network of market gardens throughout Istanbul provisioned the city with fresh vegetables. These bostans and their gardeners held a respected place in Istanbul life, contributing to the city's food and employment needs. Today, only fragments remain. Massive urban development, intense competition for metropolitan space, modernization, changing institutions and laws, and the global industrialization of food have threatened this tradition with extinction. But in spite of the overwhelming forces behind their demise, some of Istanbul's bostans persist. Efforts to support and promote the gardens, and to draw from the expertise and experience of their gardeners, are emerging. From a historical perspective, this article examines Istanbul's bostans to understand their meaning and contribution to the city's people and landscape. 相似文献

ABSTRACT. Scattered throughout the city of Toronto are more than no community gardens, sites of place‐based politics connected to the community food‐security movement. The gardens, spaces where passions for plants and food are shared, reflect the city's shifting cultural landscape and represent an everyday activity that is imbued with multiple meanings. Toronto's community food‐security movement uses gardens as one strategy to regenerate the local food system and provide access to healthy, affordable food. Three garden case studies expand on the complexities of “food citizenship,” illustrating the importance of that concept to notions of food security. The gardens reveal the role gardeners play in transforming urban spaces, the complex network of organizations working cooperatively and in partnership to implement these projects, and the way in which social and cultural pluralism are shaping the urban landscape. 相似文献

This article examines the regulation of urban public space through a study of the role of the family unit in past and present urban development in Singapore. Since the founding of modern Singapore 50 years ago, the nuclear family has remained the preferred social institution for state policies and subsequent regulation of education, housing, employment, health, leisure, social welfare and even neighborhood development. Drawing on primary government documents and field work and interviews with current and displaced small business owners on a commercial street in Chinatown, the article demonstrates how a “softer” version of spatial regulation emerged from an intersection of state commercial development policies that favored small, family-owned businesses and the extension of a family-based moral social order applied to the surrounding public spaces. The result is the regulation of Chinatown’s streets and sidewalks became inextricably bound up with the everyday operations of family-run businesses. More recently, state interest in creating an entertainment-based global Singapore has jeopardized this arrangement, as corporate gentrification threatens to displace family ownership of small businesses. 相似文献

ICT对城中村居民居住和就业迁移空间的影响——以北京5个城中村调查为例 总被引：1，自引：0，他引：1
近年来中国以互联网技术为核心的信息通讯技术(ICT)发展迅速,对居民的社会经济活动、生活方式等产生了深刻影响。本文利用问卷调查、微信访谈等方式调查了北京5个典型城中村,利用多元无序多分类logistic回归模型验证信息渠道对城中村居民居住和迁移空间的影响,结果表明：城中村住房市场非正规化从信息源头切断了居民通过互联网获取住房信息的渠道,加上城中村居民选择新住所具有就业导向和以地缘—血缘为纽带聚集的特征,信息渠道对城中村居民的居住迁移距离没有显著影响;受“就业锚点”、“距离衰减定律”和非正规就业影响,信息渠道对城中村居民近距离就业迁移也没有显著影响,但在更大空间范围内,城中村居民能通过招聘网站、社交网络等网络渠道获取就业信息,ICT的发展丰富了他们的信息获取渠道,扩大了就业空间选择,一定程度上减轻了时空制约。本文加深了关于ICT对居民日常活动空间影响、技术进步与社会平等关系的理解,丰富了居民时空间行为研究。 相似文献

ABSTRACT. Investigations of dooryard gardens, kitchen gardens, home gardens, and houselot gardens fall unequally into one of three groupings. The first are those that treat the plants in the gardens as biological entities and define a space considered a culturally controlled biological community or habitat. The second are those that consider plants cultural traits and the space defined by their positions a setting for household activities. The third conceives of plants as design elements within a garden or a landscape that frames a house or provides a setting for formal human performances. Recent decades have witnessed a broadening focus in the study of gardens, from spatial characteristics and biological content to social and cultural concerns such as reciprocity networks, contested spaces, and the concept of “dwelling.” 相似文献

In this article, we examine the sociospatial effects of market-driven social housing policies implemented in neoliberal Chile. The study area encompasses the Valparaíso—Viña del Mar conurbation and its surrounding peri-urban and peripheral municipalities. To analyze the urban dynamic between 1990 and 2005 we use data showing the allocation of social housing complexes built during three time periods, socioeconomic data disaggregated at the district level, and semistructured interviews conducted with strategic actors from the public and private sectors. We conclude that private developers are increasingly building social housing complexes in peripheral municipalities, fragmenting the sociospatial landscape and concentrating poor families in ghetto-like compounds. We also encountered local governments (municipalities) with little capacity to mobilize the resources that they hold, and communities that remain disconnected from their local representatives. 相似文献

论城市空间破碎化研究 总被引：2，自引：0，他引：2
空间破碎化是城市空间演进的客观现象,表现为城市空间单元碎化、空间分割加强、空间联系弱化和空间整体功能下降,具有空间形态的封闭性、空间联系的阻隔性和空间功能的失配性等特征,是城市品质提升和可持续发展的重要制约因素,是城市空间格局与过程分析的新内容。“空间破碎化”是对“景观破碎化”的拓展和深化,有助于从更为综合整体的空间视角研究城市。“空间破碎化”研究应遵循“格局过程刻画→形成机理分析→调控模式设计”的分析框架,围绕城市空间破碎化的概念、特征、测度、机理、动态模拟和调控模式等内容,采用景观指数、空间句法、多智能体情景模拟和地学信息图谱集成的方法进行多学科融贯的综合分析,可为制定城市发展政策、促进城市发展转型、实现城市可持续发展提供理论指导和方法支撑。 相似文献

轨道交通站域的城市物质空间更新轨迹与组织模式——以北京为例 总被引：1，自引：0，他引：1
以居住为导向的北部回龙观区域和产业导向的南部亦庄为区域,以时间剖面遥感影像图为基础,综合运用土地利用数据、实地调查与深度访谈等多种方法,判别、回顾并解译物质空间的基本变化过程,凝练物质空间的演替规律与组织模式,以期为制定科学合理的交通基础设施建设和城市综合开发方案提供支撑。研究发现：① 居住导向的物质空间组织模式,以站域内居住空间持续扩大、居民数量不断增多为特征,伴随着城乡景观和生活方式的角逐。同时,却往往忽视了产业空间与公共服务设施空间配套建设,加之高密度的人口集聚,大大降低了居住舒适度。② 产业导向的物质空间组织模式以站域内产业空间持续扩大、企业数量不断增多、配套基础设施逐步完善为特征。但居住空间与公共服务设施空间建设的时滞性显著,造成了人气不足、土地利用效益低下。③ 建立和完善轨道交通站域的物质空间组织模式知识库,将为交通导向下的基础设施建设和城市综合开发方案提供科学依据。 相似文献

With the expansion of a city, the urban green space is occupied and the urban heat island effect is serious. Greening the roof surfaces of urban buildings is an effective way to increase the area of urban green space and improve the urban ecological environment. To provide effective data support for urban green space planning, this paper used high-resolution images to (1) obtain accurate building spots on the map of the study area through deep learning assisted manual correction; and (2) establish an evaluation index system of roof greening including the characteristics of the roof itself, the natural environment and the human society environment. The weight values of attributes not related to the roof itself were calculated by Analytic Hierarchy Process (AHP). The suitable green roof locations were evaluated by spatial join, weighted superposition and other spatial analysis methods. Taking the areas within the Chengdu city’s third ring road as the study area, the results show that an accurate building pattern obtained by deep learning greatly improves the efficiency of the experiment. The roof surfaces unsuitable for greening can be effectively classified by the method of feature extraction, with an accuracy of 86.58%. The roofs suitable for greening account for 48.08%, among which, the high-suitability roofs, medium-suitability roofs and low-suitability roofs represent 45.32%, 38.95% and 15.73%. The high-suitability green buildings are mainly distributed in the first ring district and the western area outside the first ring district in Chengdu. This paper is useful for solving the current problem of the more saturated high-density urban area and allowing the expansion of the urban ecological environment. 相似文献
