湘南地区毗邻赣、粤、桂三省,地理位置特殊,是一个复杂的地理单元。及至清代,湘南地区已是湖南省乃至全国铜、铅、银等矿业生产的主要区域。长达数百年的矿产开采与冶炼,促进了地方社会的经济发展,也给当地的生态环境带来深远影响。由此,湘南官绅民各界对矿业开发引发的环境问题亦有因应,“坑冶十害论”和“九嶷山封禁案”即为其集中体现。开矿采砂本为解决贫民生计而采取的措施,但因破坏风水、污染水土等一系列影响环境的后果,以致出现开矿与禁矿之争,使得湘南地区矿业开发一度出现波折。这两例个案亦折射出在“重本抑末”的传统社会中地方官绅士民在生计与风水之间的离合关系。地方社会以保护风水为由严禁矿冶,在一定程度上遏止了生态环境的破坏与恶化,不过,其在环保方面发挥的作用也不宜被高估。 相似文献

基于2013年宜居北京大规模问卷调查数据和北京市基础地理信息数据,探讨了北京市居民宜居满意度的空间特征,并运用多层线性模型进一步分析城市建成环境对居民宜居满意度的影响。研究发现,北京市宜居满意度总体良好,空间分布存在中心高边缘低的特征。城市建成环境对居民宜居满意度存在显著影响。其中,丰富多样的服务设施、适宜的人口密度以及便捷的公共交通能够促进居民宜居满意度提升,而单一的土地利用和邻近商业中心则会降低居民宜居满意度。除此之外,城市建成环境对宜居满意度的影响在空间上存在异质性,同时建成环境对宜居满意度的影响在不同阶层中存在差异性,人口密度和服务设施多样性对中低收入群体的宜居满意度提升明显。 相似文献

Increasingly, children are residing in urban environments, yet little is known about the urban affordances for children. A place-based approach was employed to map the urban experiences of over 1300 children residing in Helsinki (Finland) and in Tokyo (Japan) in terms of meaningful places (affordances), travel mode and accompaniment to these places. Shared affordances were considered behavior settings, and audited on-site by trained experts for their main function, land use, openness, and communality. Significant differences were found between countries for all affordance categories. Although differences in behavior settings were observed between countries, a number of patterns emerged: outdoor settings and those with shared communality were the most prevalent behavior settings, traffic settings were predominantly evaluated negatively and commercial and indoor settings most positively. Findings suggest that although the context is important, independent mobility and the possibility to actualize environmental affordances seem to be fundamental in both contexts as the key criteria for environmental child-friendliness. 相似文献

Urban homesteading and intensive mothering: (re) gendering care and environmental responsibility in Boston and Chicago 总被引:1,自引:0,他引:1
Brenda Parker Oona Morrow 《Gender, place and culture : a journal of feminist geography》2017,24(2):247-259
In this article, we explore how normative ideologies of good mothering are being reproduced and contested through urban homesteading, a sustainable lifestyle that emphasizes household self-provisioning. Urban homesteading practices may include gardening and urban agriculture, canning, and pickling, and a variety of do-it-yourself and craft projects. Based on qualitative research with 19 urban homesteading households with children in the Boston and Chicago Metropolitan areas, we argue that urban homesteading discourses and practices reflect and align with intensive mothering ideologies in the United States. Intensive mothering ideologies encourage a selfless devotion of physical, emotional, and mental energy to childrearing, and are often associated with individualized, privileged, and gendered subjectivities. We find these intensive mothering ideologies especially visible in the ways that mothers perceive and respond to environmental risk by adopting and enacting urban homesteading labors. We also note that the choice to respond to risk by homesteading is often, but not always, mediated and animated by economic, temporal, and social privilege. In this way, urban homesteading and surrounding discourses may inadvertently raise the bar of ‘good’ motherhood in ways that demand more of women and marginalize or burden mothers with less resources and privilege. However, rather than dismiss homesteading entirely on these grounds, we suggest that it may be possible to harvest impulses of care, connection, and collectivity associated with homesteading in ways that benefit rather than burden all mothers. 相似文献

Drawing together insights from neo‐Innisian geography and environmental history, this paper explores the landscape and environmental changes engendered by ‘cyclonic’ patterns of development associated with uranium production at Uranium City, Saskatchewan. Strong postwar demand for uranium led to the establishment and rapid expansion of Uranium City on the north shore of Lake Athabasca as a ‘yellowcake town’, dedicated to producing uranium oxide concentrate to supply federal government contracts with the US military. In spite of optimistic assessments for the region's industrial future, the new settlement remained inherently unstable, tied to shifting institutional arrangements and external markets, and haunted by the spectre of resource depletion. The planning and development of the townsite at Uranium City reflected both neocolonial desires to open the north to Euro‐Canadian settlement and efforts by the state to buffer the stormy effects of resource dependency. Ultimately, however, quixotic government efforts to implant an outpost of industrial modernity in the Athabasca Region failed to forestall the inevitable winds of change, which left in their wake destructive legacies of social dislocation and environmental degradation, already evident with the near‐collapse of the uranium export market by the early 1960s. 相似文献

The pre-Magdalenian phase of the Côa River Valley open-air rock art is mostly distributed at the boundary between the rocky valley slopes and the floodplain that correspond to the most favourable geomorphological setting for the preservation of pecked and deeply superposed engravings of the most famous artistic phase of the area. The natural vertical panels of the engraved art located at this geomorphological interface have suffered weathering during two cold events of the Lateglacial. They were buried by several colluvial and alluvial deposits. The reconstruction of the sedimentary and archaeological context of the CôaRiver Valley engraving permits a better assessment of the preservation processes and interpretation of Palaeolithic open-air rock art. 相似文献

被边缘化的群体和被边缘化的法律——对富士康“跳楼门”事件的法律思考 总被引:1,自引:0,他引:1
富士康"跳楼门"事件属于社会转型时期被边缘化的劳动者极端地反映自身利益诉求的方式。该事件不仅暴露出劳动密集型企业管理模式的弊端,也折射出我国现行的法律体系对于劳动者权益保障的缺位。同时,富士康在对"跳楼门"事件的处理中也存在着与法治精神和现行法律规定相违背的地方。本文就富士康"跳楼门"事件所涉及的相关法律问题进行初步探讨。 相似文献
