未来城市研究范式探讨 ——数据驱动亦或人本驱动   总被引:2,自引:3,他引:2  
秦萧  甄峰  魏宗财 《地理科学》2019,39(1):31-40
回顾传统城市研究范式,指出其“重宏观社会经济发展研究、而轻微观居民个体需求分析”这一问题,在此基础上,综述了城市研究领域的大数据热潮,进而抛出“数据亦或人本驱动?”的争论;从大数据自身的缺陷、智慧社会的到来及未来城市发展维度3个方面分析未来城市研究数据和人本之间的关系,提出应遵循“人本驱动、数据支撑”的研究范式,扩展了“人本驱动”的内涵。最后,从城市居民生活(生活圈打造、社会网络构建、满足生命周期需求)、企业生产(人才流动网络构建、产业链打造、营销模式转变)、政府管治(数据共享与融合、社会服务供应、公众参与机制创新)3个方面提出了未来城市研究的新框架。  相似文献

Human geographers' research into lay responses to burgeoning environmental issues has highlighted their mediated and contingent constitution. Situated within the discipline's cultural turn, this work has challenged prevailing informational and cognitive approaches to sustainability. In doing so, however, potentially informative concepts and findings from environmental psychology have been sidelined. In this paper I attempt a modest allying of the two sub-disciplines, outlining their differences and similarities, and arguing that environmental psychology can triangulate with human geography, as well as challenge tendencies within human geography literatures to simplify the 'psychological' subject.  相似文献

粘土矿物对环境污染的防治作用   总被引:8,自引:0,他引:8  
粘土矿物具有比表面积大、孔隙多以及极性强等特征,因而有较强的吸附性、离子交换性和膨胀性,对水体中各种类型的污染物质有良好的吸附性能,并使土壤有一定的自净作用。粘土矿物的膨胀性及低导水率使它能作为有效的密封物质,在放射性废料的埋置过程中产生理想的封闭作用。另外由于粘土矿物成本低、再生容易,所以在环境污染的防治中有广阔的应用前景。  相似文献

Leisure plays an important role in people's happiness; therefore, facilitating participation in leisure activities has become one of the pathways to improve urban residents' wellbeing and realize high-quality new urbanization. This study focuses on migrant workers' leisure behavior and quality of life. Based on the self-selection hypothesis and structural equation modeling analysis, this study explores the influence of both leisure environment and leisure attitude on leisure behavior. First, our analysis of the leisure environment revealed that leisure behaviors differed according to leisure environments. Residents of resource-rich communities had the longest leisure time, a medium leisure distance, and a positive leisure attitude. Communities with medium leisure resources had the shortest leisure time and closest leisure distance. Communities with scarce leisure resources had the longest leisure distance and the most negative leisure attitude. Second, by examing the match of leisure attitudes and leisure environments, we found that the average leisure time of matching groups was longer, and they generally spent their leisure time within 1 kilometer around the community. Furthermore, the leisure time of residents in communities with scarce leisure resources did not show significant differences. For the mismatching groups of leisure attitudes and environments, about 60% of the residents spent less than 2 hours on average per day, and the leisure distance did not show any significant difference. Third, the structural equation modeling analysis indicated that both attitude and environmental attributes can affect migrant workers' leisure behavior; they further interact with each other and jointly determine residents' leisure behavior. The temporal (leisure time) and spatial (leisure distance) dimensions of leisure behavior are influenced by different mechanisms. Leisure attitude has the most direct effect on leisure time, while the effects of leisure environment on leisure distance are complex. Socio-demographic attributes affect leisure environment, leisure attitude, and leisure behavior. Men and women do not differ in terms of leisure time, but women's leisure distance is greater than men's. Age has no significant effect on residents' leisure behavior, but younger persons enjoy more leisure. Monthly household income has a significantly negative effect on residents' leisure time and leisure distance, while it has a significantly positive effect on leisure environment. Persons with higher education pay more attention to their leisure life, and spend more time and travel to participate in more leisure activities. This study makes three contributions. First, in the context of leisure scenarios, it promotes the combination of self-selection effect and rational behavior theory, and fully considers the role played by attitude in the mechanism of environmental influence on behavior. Existing studies of transportation mostly follow functionalism in the pursuit of efficiency, and the scope and ability of residents' self-selection is limited. This study of leisure behavior empirically demonstrates the importance of leisure environment and leisure concepts cultivation. Second, the study of migrant workers' leisure provides inspiration for the construction of new urbanization. In China's rapid urbanization, migrant workers have made positive contributions to the development of cities at the sacrifice of their youth and health. The leisure self-selection effect can be used to improve residents' leisure participation and subjective well-being by enhancing the community's leisure environment. Third, the migrant worker group is diversifying. With the deepening of new urbanization, their daily lives are changing and they are making continual efforts to adapt to urban life, rather than remaining passive. © The Author(s) 2023.  相似文献

Effective risk communication is central to good environmental risk management. While studies have shown that newspapers are the primary source of information to the public regarding environmental issues, little is known about how environmental news is used as a risk‐communication tool. This article explores the role of local information systems in risk communication, using newspaper content analysis as well as in‐depth interviews with journalists and community residents to develop a case study of an environmental assessment process for a nonhazardous industrial‐waste landfill. Results indicate that risk messages were chosen and shaped by journalists on the basis of their own exigencies. In addition, while newspapers were a major source of risk information, their impact was mitigated by resident distrust and access to other information sources, most notably their own personal information networks. These results have implications for environmental policy, as decision makers often use—either passively or actively—print media as a risk‐communication tool.  相似文献

This study examines whether an ecological worldview—operationalized by the New Ecological Paradigm (NEP) Scale--serves as the source of coherence of Environmental Concern (EC). Using data on four samples from the 1992 Gallup “Health of the Planet” Survey and the 2003 and 2010 Chinese General Social Surveys, we found that in all samples not only is the NEP the most powerful predictor of EC, but it also mediates the effects of socio-demographic variables on EC as hypothesized. The results confirm that the NEP is the source of coherence of EC, making it a meaningful construct.  相似文献

The “White male effect” has been presented in past literature as a way to explain the tendency for White males to have lower environmental concern and risk perceptions than female and non-White individuals. Recently, research has proposed the “White male effect” may be a “conservative White male effect,” due to findings that political ideology impacts environmental concern. This study used a sample of young college-educated adults from Generation Z to test whether the conservative White male effect is present for environmental concern and ambivalence toward a proenvironmental worldview in this younger generation. Online surveys were distributed to undergraduate students at a large northeastern university in spring of 2016. A total of 1,940 surveys were returned. Results showed a lack of a unique White male, or conservative White male, effect above and beyond differences explained by gender, Whiteness, and political affiliation. The implications of this effect’s absence are discussed.  相似文献

全球环境变化研究与人文地理学的参与问题   总被引:3,自引:0,他引:3  
全球环境变化是当今世界关注的热点问题之一。随着全球环境变化研究的深入,人们更加深刻地认识到全球环境变化不单纯是自然环境系统本身的科学问题,而是包括国际政治、经济和社会人文诸多方面综合的、复杂的问题,所以全球环境变化研究引起了相关学科领域越来越深的参与,愈来愈呈现出自然与人文要素综合集成研究的趋向。过去的科学实践已证明地理学是全球环境变化研究的重要力量。地理学参与全球环境变化研究,不完全归因于它在探讨人类-环境相互作用中具有综合研究的学科特性,部分原因是学科自身发展的需要。本文强调我国人文地理学要积极参与全球环境变化的相关研究,初步讨论了人文地理学要关注的相关理论和实践问题、人文地理学参与的途径及能力建设问题。  相似文献

浙江省经济增长与环境质量演进关系的实证研究   总被引:4,自引:0,他引:4  
基于浙江省1981-2006年的环境与经济数据,运用三次环境库兹涅茨模型对工业"三废"排放量与经济发展的关系进行模拟,研究发现浙江省工业"三废"排放与经济发展之间的关系不完全符合典型的"倒U"型的库兹涅茨特征,而是呈N型波动或同步关系。其中,工业废水排放量的EKC呈"U+倒U"型曲线组合得到的"倒N"型,工业固体废弃物产生量的EKC呈"倒U+U"型曲线组合得到的N型,工业废气排放量的EKC与经济发展关系呈同步关系,目前这些曲线尚未达到转折点,仍处于上升期,表明浙江省目前还未进入工业化后期,仍处于由中期向后期转变的过程中,并据此提出了浙江省实现经济发展与环境保护双赢目标的政策建议。  相似文献

山岳型旅游区人文建筑环境后效与调控模型   总被引:4,自引:1,他引:4  
全华 《山地学报》2002,20(6):706-711
许多山岳型旅游区内或其流域上游,都建有人文建筑,而且在急剧增多,导致自然环境日趋恶化,其中乱建疗养院和旅馆的影响最为严重。通过地监测并全面分析张家界环境演变趋势,发现住宿施对环境的影响,比其他游乐设施更为明显。张家界国家森林公园生态环境的脆弱因子是金鞭溪水质。金鞭溪水质恶化主要表现为蓝藻,绿藻迅速繁殖,感官质量下降。主要原因是磷污染较重,总磷年均值100%超标。本文提出了基于环境脆弱因子的动态阈值调控模型,通过计算得出:在不超出张家界景区最为脆弱的环境因子-金鞭溪水质标准:总磷≤0.02前提下,金鞭溪上游接待区住宿设施生态阈值的动态系列:春季临界床位数为1186,夏季为3057,冬季为545,秋季为333。目前的建筑规模已超过了金鞭溪上游接待区住宿设施生态阈值。  相似文献

Attitudes towards wolf policy are likely to be driven by perceived differences in political power between urban and rural groups. Using Swedish survey data collected in 2014 and structural equation modeling, I evaluated the effects of political alienation. Political alienation mediated the effect of having an urban or rural place of residence on attitudes towards wolf policy. Politically alienated individuals also preferred more extreme policy options than other respondents, while being less likely to approve of the current wolf policy in Sweden. These findings suggest that political alienation drives attitude polarization in wolf related social conflicts. Awareness of these underlying power asymmetries could possibly increase both policy legitimacy and management efficiency. This highlights the importance of accounting for social context in relation to policy-making and conservation efforts related to wolves.  相似文献
