当代中国环境治理的权利观

当代中国环境治理的权利观是指从权利的角度去考察、理解当代中国的环境治理,推进当代中国的生态文明建设事业。从这一角度来看,环境相关权利是当代中国环境治理的基本价值目标,也是重要的治理工具。所谓环境相关权利,是指环境治理有助于保障的环境权、生存权和发展权、生命权和健康权,以及在环境治理中可以运用到的知情、表达、参与、监督等权利。当代中国环境治理的权利观,在理论上符合生态文明建设的以人为本原则,符合国家治理体系和能力现代化的方针和取向,在实践上也能够揭示当代中国生态文明建设和环境治理的基本特征、精神实质和发展方向,既具有阐释性,也具有建构性。     

工业大气污染源排放绩效定量评价及应用

工业源治理是改善环境空气质量的重要途径,而如何开展精准治污仍然是目前亟需回答的问题.以天津市西青区为例,基于第二次全国污染源普查数据,对工业企业开展污染物排放绩效定量评价,并深入探究排放绩效评价应用于工业源精细化管控治理的意义、可行性以及存在的问题.结果发现,西青区各行业的排放绩效水平差异较大.污染物排放绩效水平与行业企业的自身属性、发展规模和管理水平有较为密切的关系.整体来看,家具制造业、金属制品业、黑色金属冶炼和压延加工业等生产工艺本身产污量大且中小型企业居多的行业排放绩效水平偏差,而以计算机通信和其他电子设备制造业、汽车制造业为代表的高端行业排放绩效水平整体偏好.各行业中不同企业排放绩效差异也较大,其中金属机械制造类行业中绩效最差的11家企业工业产值对行业贡献0.06%,而PM排放量贡献达到8.50%;橡胶和塑料制品业中绩效最差的19家企业工业产值对全行业贡献4.76%,而VOCs排放量贡献却达到43.59%.同时,分别参照生态环境部相关技术指南和绩效评价结果设计减排方案,发现后者在减排同等规模污染物排放量时,减排成本最高可低于前者约90%.各行业、企业污染物排放绩效的差距,经济效益和环境成本的不协调,以及排放绩效评价对于精准减排的重要指引作用,充分证明开展排放绩效评价的必要性.结果表明污染物排放绩效评估可有效支撑宏观产业结构调整和中观、微观的工业企业环境治理,为精准治污提供重要参考路径.

A fresh perspective on food safety in Canada: risk communication,public involvement,and the impact of the 2008 listeriosis outbreak

While the listeriosis outbreak of 2008 brought attention to food safety decision making in Canada, little of that attention was placed on public involvement and risk communication. With a primary focus on Health Canada (HC) and the Canadian Food Inspection Agency (CFIA), this article describes the state of microbial-related public involvement and risk communication undertakings and suggests ways in which improvements can be made. The findings show that public involvement and risk communication activities have been strengthened since the outbreak, but they have become neither dialogical nor highly participatory. HC engages with experts to a far greater extent than with the lay public and it has fallen short in fulfilling its stated commitment to openness and transparency. Furthermore, both HC's and the CFIA's approach to risk communication has been overly general, has failed to provide opportunities for dialogue with vulnerable and more general groups with whom it is communicating and is not rooted in foodborne surveillance data. Public involvement in food safety governance would be improved if HC provided the lay public with a seat on advisory committees and improved its public involvement reporting methods. HC and the CFIA could also make risk communication improvements by creating opportunities for dialogue between officials and the general public, and by exploring alternative risk communication vehicles, such as food labels.     

大气环境科学综合数据采集共享平台建设及应用研究

为实现大气重污染成因与治理攻关项目数据的统一管理和数据共享,基于美国电子政务共享框架（Federal Enterprise Architecture Framework,FEA）方法论和数据中台思想,采用JAVA平台和SOA框架,以大气重污染成因与治理攻关项目科研数据为主,整合全社会大气科学数据资源,面向京津冀、汾渭平原大气污染成因与治理改善分析的核心业务需求,建设集多源异构数据采集、治理、共享、分析、发布于一体的大气环境科学数据采集与共享平台;建立完善的线上数据治理流程,采用多种算法实现大气业务数据集的实时质控;采用分级、分权限的数据共享机制和共享接口动态编辑技术,建立一站式数据枢纽.结果表明:①建立大气科学数据规范分类体系,提供从原始数据、二次数据产品、大气攻关信息发布等多种类型的数据共享服务.②建立海量多源异构综合数据集,包括空气质量、组分、污染源、气象、健康等11类,数据总量4.3 TB,包括7.5亿条数据和66万个文件.③开发交互式GIS服务和线上评估分析工具,实现环境空气质量评估、气象影响分析、组分变化、污染源统计四类主题数据服务.④向大气重污染成因与治理攻关项目各课题组、七省（市）提供多种形式共享,开放104个数据接口,实现21亿条数据、2万份文件、15个专题共享,有力地支撑了大气重污染成因与治理攻关项目的各项研究.

针对巷道蝶叶塑性区顶板破坏深度大、变形剧烈、冒顶事故频发等问题,综合现场调研、理论分析、数值模拟等方法,考虑巷道顶板不同服务阶段的变形破坏特点,研究分析了巷道顶板破坏失稳机理和不同层位顶板的控制要点,提出了以冒顶控制为主的顶板层次控制技术,阐明了辅助支护材料、普通长度锚杆、接长锚杆、长锚索对不同层位顶板的层次控制原理。据此,在保德矿81306工作面回采巷道蝶叶塑性区顶板进行了层次支护设计,并进行了顶板下沉量和接长锚杆支护力监测,结果表明:以冒顶控制为主的巷道顶板层次支护体系较好的维护了顶板整体稳定,保证了巷道安全与正常服务。     

A System for Measuring Vertical Concentration Profiles of Gaseous Pollutants,Using Carbon Dioxide as a Case Study

An electronically-controlled sampling system, characterised by its organ pipe design, has been developed for sampling air sequentially, at different heights within the breathing zone. Data are automatically logged at the different receptor levels, for the determination of the average vertical concentration profile of gaseous pollutants. The system has been coupled to a carbon dioxide monitor and used in a brief study of the spatial and temporal variation of indoor carbon dioxide concentration. The system can easily be extended for different heights or modified for use with other types of gas monitor. The results of a trial run, which was carried out in a coffee room, are presented and applications of the Organ Pipe Sequential Sampling (OPSS) system are discussed.     

Examining municipal response to a provincial climate action planning mandate in British Columbia,Canada

The engagement of UK local authorities is vital if national government is to meet its climate change commitments. However, with no mandatory targets at local government level, other drivers must explain engagement. Using a Geographic Information System, this study compares the spatial distribution of action on climate change based on past actions and stated intentions to a suite of relevant independent variables. The Action Index created is among the first to quantify climate change engagement beyond a simple binary measure and provides a useful comparative study to recent work in the USA. The Index enables investigation of both mitigation and adaptation, which show different trends in relation to some variables. The study shows that action is strongest where the voting habits of the local population suggest environmental concern and where neighbouring local authorities are also engaging in action on climate change. Physical vulnerability to the effects of climate change is a motivator for action only where the dangers are obvious. Action is less likely where other resource-intensive issues such as crime and housing exist within a local authority area.     

Some lessons for resilience from the 2011 multi-disaster in Japan

With the goal of resilience becoming ever more present in diverse policy discourses, it is important to reflect critically on its meaning and realisation. In this viewpoint, we re-emphasise that understanding the systemic nature of social and ecological interactions and interdependencies is fundamental to developing resilience to shocks and stresses in whatever context they materialise. Through the lens of the 2011 Japanese multi-disaster, we reflect on some of the difficulties in generating knowledge to underpin resilience-building processes and illustrate some dilemmas inherent in seeking to cultivate resilience in practice. Events in Japan underscore the complex vulnerabilities of place in multi-hazard scenarios and highlight, in particular, the choices to be made in determining which systemic interactions are to be imagined, characterised, assessed and forewarned and which are not. These events also emphasise that while resilience ultimately must be located where consequences are felt, strategies for a resilient future have to take on the multi-scale interactions and tensions within which local processes are embedded. There are dangers, we argue, in thinking about resilience in overly simple and non-systemic ways and in responding to these challenges only as a matter of extended techno-managerial competence.     

Sub-national level of participation in international environmental cooperation: the role of Shiga Prefecture for Lake Biwa environment in Japan

From a state-centric view, sub-national level of participation at the international level can be only feasible if it is an active part of national policy. In the case of Shiga prefectural government's initiative for international lake-environmental cooperation, however, sub-national actors came to see themselves as direct players in the absence of national policy. This study examines under what conditions and in what ways such sub-national level of participation takes place by conducting a case study of Shiga's collaboration with the United Nations Environmental Programme (UNEP) over lake-environment risk reduction. The article finds that the process of Shiga's participation in transnational governance will have less chance of being duplicated effectively in other Japanese sub-national governments. Shiga's cooperation with the UNEP was primarily driven by the ad hoc bottom-up political mobilisation of the sub-national actors. In general, without institutionalised channels for sub-national governments to participate in the regional/international level, sub-national governments need to mobilise resources on such an ad hoc basis and only pioneering sub-national actors are capable of effectively engaged on unfamiliar territory with the formation process of transnational governance.
