如今高速发展的中国城市正饱受"垃圾围城"之痛。"人生活在城市里,城市受困于垃圾中"已是当前的真实写照。"十二五"以来,地方政府虽然出台了相关政策,但是面对城市人口不断积聚的现状,我国仍面临垃圾难排、难运、难处理、难管理的窘境,"垃圾围城"的悲剧仍在上演。"垃圾围城"的风险不容忽视,因此"垃圾围城"现状和对策的研究必须被重点关注。文章基于"收集信息—揭示信息—综合研判—形成方案"(Data-Information-Intelligence-Solution,DIIS)分析框架,运用"谷歌地球"(Google Earth,GE)及地理信息系统(Geographic Information System,GIS)软件识别31个直辖市和省会城市非正规垃圾填埋场的个数、面积及形成情况,以得出"垃圾存量"数据。进而,基于"驱动力-状态-响应"(Driving Force-Status-Response,DSR)风险评价模型识别31个省会城市的"垃圾围城"风险,通过分析现状、识别风险源、理清风险的发生发展机制,进而为规避垃圾围城风险进行管理机制设计,以期为政府部门降低城市"垃圾围城"风险献力。 相似文献

Do low-skilled workers benefit from the growth of high-technology industries in their local economy? Policymakers invest considerable resources in attracting and developing innovative, high-tech industries, but there is relatively little evidence on the distribution of the benefits. This paper investigates the labour market impact of high-tech growth on low and mid-skilled workers, using data on UK local labour markets from 2009–2015. It shows that high-tech industries – either STEM-intensive ‘high-tech’ or digital economy – have a positive jobs multiplier, with each 10 new high-tech jobs creating around 7 local non-tradeable service jobs, around 6 of which go to low-skilled workers. Employment rates for mid-skilled workers do not increase, but they benefit from higher wages. Yet while low-skilled workers gain from higher employment rates, the jobs are often poorly paid service work, so average wages fall, particularly when increased housing costs are considered. 相似文献

资源节约评价及其驱动机制分析——以南京市为例 总被引:2,自引:1,他引:1
随着城市化进程的不断加快、城镇建设规模的日益扩大,城市成为人类经济社会发展的主要空间载体。然而普遍存在的资源浪费现象已严重制约城市经济社会的协调与可持续发展,建设节约型城市就成为当今资源紧缺状态下的必然选择,也是落实科学发展观、建设效益城市的基本要求。本文从投入型节约、技术型节约、循环型节约、消费型节约、保护型节约等5个方面构建资源节约程度的评价指标体系,以资源极度匮乏且又是综合性工业生产基地的南京市为例,进行资源节约程度的评价,并就各指标1986年~2006年的变化特征进行分析,最后借助GDP增长拉动分析技术测度资源节约的驱动机制。研究结果表明:南京市的资源节约水平总体上在波动中不断提高;投入型节约是拉动资源节约的主导力量,消费型节约和技术型节约对节约型城市建设也起了重要的推动作用。最后提出资源节约型城市建设在今后工作的重点及方向。 相似文献

文学翻译不是一劳永逸的,重译是翻译实践的必然趋势,有它的必要性和意义。狄更斯的作品《双城记》曾被罗稷南翻译过两次,又修订了一次。较旧译,重译本做了大量的修改,修正了误译,在遣词造句、句子逻辑性以及词语规范化使用方面加以完善,体现了强烈的意识形态,而且运用符合时代特点和语言潮流,增强了译本的可接受性。基于重译的必要性和意义,从语言、文化和意识形态的可接受性层面对比两译本的差异,以期探讨译者在重译过程中所受的制约,以及重译的价值。 相似文献

就世界范围来看,大众文化的产生是与都市化相伴随的,它与都市的发展基本呈同步态。然而在中国,目前并不存在成熟形态的都市。大众文化与都市的发展之间存在着不小的错位与落差。当代中国的大众文化更多是在向西方的都市化进程看齐。还原到本土城市的现实语境下,这种视角势必带有某种想象性的成分。以想象中的都市为研究对象,选取大众文化的角度进行解析,进而挖掘当代中国大众文化都市想象的实质,将有助于剖析想象化叙事下国人心理的变化轨迹。 相似文献

Delivering public services to citizens via the Internet is the basic goal of E-government. Although websites are becoming essential elements of public e-services in local public administration in China, little is known about their efficiency and effectiveness. The objective of this paper is to evaluate the actual status of Web-enabled public services to citizens in municipal e-government implementation in the Yangtze River Delta. Eight categories of public services to citizens delivered through the Internet have been identified in the websites of the 14 local municipal governments. These public services include birth, marriage, domicile register, education, social security, public utility, health and traffic. Using the methodology of service maturity, this study evaluates the quality and usage of public e-services to citizens in the Yangtze River Delta. The results of this study show that almost all city governments are shifting from the traditional bureaucratic paradigm to the e-government public service paradigm, albeit with significant differences in public e-services level in these cities. At present, e-government public services to citizens in almost all the cities studied are mostly limited to on-line presentations of government information with a low degree of development of interaction and on-line transaction. The municipal governments and policymakers in the near future will have to strengthen the interactivity of their websites with citizens and improve the on-line transaction level in order to deliver citizen-centric public e-services. 相似文献
