供水管网震后流量监测点的动态分级优化布局研究

为了提高管网地震监测点布局的准确性和合理性,基于管网微观水力计算模型和动态分级法,提出供水管网震后流量监测点的动态分级优化布局模型。首先,利用管网微观水力计算模型计算管段流量的影响系数,构建管段的影响系数矩阵,并利用信息熵确定管段权重;其次,标准化处理影响系数矩阵,通过聚类迭代提出供水管网地震流量监测点优化布局的动态分级方法,对供水管网震后流量监测点进行优化布置分级评定;最后,根据工程实例进行方法实践,结果表明:供水管网中的管线分类较为科学合理,地震监测点在供水管网上分布也比较均匀,而且该模型在一定程度上消除了人为因素的影响,保障了震时管网的监控效果和日常建设的合理性。

基于平衡计分卡原理,结合网站特点,建立了大气环境监测数据共享网站绩效评估模型。以共享网站的战略愿景为模型框架的中心,以财务、顾客、内部程序、学习与成长等4个基本维度为一级指标,构建了绩效评估指标体系,并采用层次分析法确定了各指标的权重。利用该模型对长三角区域空气质量预测预报系统和宁波市空气质量预报预警平台的大气数据共享模块进行实证研究,绩效评估结果均为良好。     

《环境监测 分析方法标准制修订技术导则》(HJ 168—2010)对土壤环境监测标准制修订适用性探讨

针对土壤环境监测的复杂性和特殊性,从空白试验、检出限、方法验证、质量控制和标准文本等方面,指出了《环境监测分析方法标准制修订技术导则》《HJ 168—2010》对土壤环境监测标准制修订工作的适用性和执行中存在的问题。提出,为保证土壤标准制修订质量和标准执行质量,应研究适宜土壤监测方法标准的质量控制指标体系和评价体系,及时修订《HJ 168—2010》或发布补充要求;对现有土壤监测方法标准进行技术评估,加强对于土壤标准制修订工作的指导和监管。     

新形势下环境质量综合分析思路探讨

随着中国共产党第十九次全国代表大会的顺利召开,环保"大部制"改革、环境监测垂直管理制度改革以及国家"大气十条""水十条""土十条"的全面实施均对生态环境保护、环境监测乃至环境质量综合分析工作提出了新要求。新形势下,环境质量综合分析应与时俱进、开拓创新,进一步优化工作机制,加强系统分析,增强综合分析报告的科学性、规范性、时效性、精准性、客观性等,强化技术与能力支撑,更好发挥环境监测对环境管理和决策的引领作用。     

基于变权灰色云模型的江苏省水环境系统脆弱性评价

水环境系统脆弱性是水资源利用与生态环境研究的热点问题,通过研究水环境系统的内在机理,综合考虑影响水环境系统脆弱性的资源、环境、经济、社会等因素,借助驱动力-压力-状态-影响-响应-管理（DPSIRM）框架构建水环境系统脆弱性评价指标体系。在此基础上,构建基于变权灰色云模型的评价方法,对2004~2014年江苏省水环境系统脆弱性进行评价。结果表明：2004~2014年水环境系统脆弱性指数由47.056提高到63.210,脆弱性等级由“重度脆弱”演化为“中度脆弱”,并长期维持在“中度脆弱的”等级,2014年出现了向“轻度脆弱”状态转变的趋势。分析各个子系统对水环境系统脆弱性影响程度可知,影响子系统和响应子系统对江苏省水环境脆弱性系统的影响程度逐年增加;而压力子系统和管理子系统对水环境系统脆弱性的影响程度逐年下降;其它子系统对水环境系统脆弱性的影响维持在一定水平小幅度波动。     

Media Storms and Policy Expertise: How Environmental Beat Journalists Gained Influence During a Shale Gas Controversy

This article examines the conditions under which environmental beat journalists can gain credibility as expert informants. It shows that media storms foster a particular dynamic that can add to this credibility. Comparing a media storm over shale gas development in Quebec with regular coverage of the same issue in British Columbia, this article shows that the coverage space given to environmental beat journalists during a media storm can render their alliance with protest groups mutually beneficial. Beat journalists can benefit from the willingness of these groups to participate in their stories, while the groups benefit from increased visibility. Beat journalists also benefit by being perceived as expert informants in policy networks, a role that they use to encourage policy-makers to take the concerns of protest groups seriously. This dynamic also increases the negativity of the news coverage. The article makes a contribution to knowledge on the role of environmental journalists in policy-making processes.     

The Dynamics of Justification in Policy Reform: Insights from Water Policy Debates in Ireland

Policy reform can be complex and fraught with contending arguments. Although much research has been conducted into the politics of coalition formation, less attention has been devoted to legitimating logics in policy reform. Drawing on the work of Boltanski and Thévenot, this exploratory study addresses this deficit by examining the influence of justifications deployed in policy debates. The paper analyses the role of shifting reasoning in contentious debates concerning attempts to reform water policy, including the introduction of domestic water charges in Ireland. Employing data from parliamentary deliberations, the paper traces the changing forms of justification used by those favouring and opposing the reforms. This examination suggests the importance of aligning an argument’s content with the shifting context into which it is introduced. The paper highlights the benefits of an investigative approach concerning policy justification for understanding policy reform dynamics at the intersection of politics and environmental communication.     

Shifting Baselines: Conveying Climate Change in Popular Music

Popular music is a generation-specific zeitgeist, while music affords otherwise unobtainable engagement with environmental themes. Despite being the most widespread form of music there is a paucity of scholarship on climate change vis-à-vis popular music. In turn, this article explores how popular music may provide a soundtrack that narrates the rapidity of contemporary biophysical change. Approaches of conveying versus communicating climate change in music are considered across a spectrum of musical forms, from contemporary and historical popular music to contemporary classical music and sound art. The article applies the framework of shifting baselines to music engaged with environmental change in order to formulate a closer relationship between objective and quantitative intergenerational biophysical change and subjective and qualitative socio-cultural change. To cease losing track of such inexorable degradation, the article speculates on future musical forms that may obviate such intergenerational myopia by conveying and/or communicating the unprecedented rapidity of biophysical change.     

Preserving Wilderness or Protecting Homelands? Intersections and Divergences in Activist Discourses About Mining in Ontario’s Far North

Northern Ontario’s Ring of Fire/Wawangajing controversy constitutes a complex site of debate about the risks and benefits of mining in an area of major ecological significance that is also the ancestral territory of nine First Nation communities. This paper investigates the rhetorical alignments and divergences in public calls by Matawa First Nations tribal council and the Ontario Wildlands League for stronger environmental assessment of mining projects than that favoured by the Canadian government. Tracing the terminologies each group uses to describe the affected region and its inhabitants in its activist rhetoric about EA offers insight into the contingent, shifting ways in which wilderness advocacy and Indigenous justice discourses may speak together yet distinctly within contemporary environmental-natural resource disputes.
