Communicative Aspects of Environmental Management by Objectives: Examples from the Swedish Context

Management by objectives (MBO) is a technique for integrating ecological concerns into national political and administrative structures. Politicians determine environmental objectives and interim targets to be implemented and assessed by civil servants in national, regional, and local contexts. Well-developed organizational communication is a prerequisite for MBO. However, communication-related obstacles can arise when using MBO in public environmental management. We examine communicative aspects of environmental MBO, looking specifically at the implementation, administration, and assessment of Swedish environmental quality objectives. Our argument is illustrated by quotations from individual and focus group interviews. We conclude that communicative problems may arise, because different actors interpret messages from different perspectives, depending on their agendas, prior knowledge and experience, and positions in the administrative system. It is crucial to recognize the dialogical aspects of communication, by involving the receiver of a message in a process of response. In addition, the different timeframes underlying different arguments could contribute to misunderstandings between actors involved in handling environmental issues. In assessing the achievement of environmental objectives, indicators are used as communicative tools. It is important to investigate whether and how these indicators contribute to the de- and recontextualization of environmental objectives.

环境污染治理工程管理对策分析

随着环境问题的日益突出,环境保护以及环境治理越来越迫切,由于造成环境污染问题的因素特别多,在对污染原因没有明确了解的情况下,盲目的着手进行环境污染治理工作,将会很难达到预期的治理效果。因此,作者从环境污染治理工程管理入手,进一步探索导致环境污染问题日益严重的根本原因,并详细分析加强环境污染治理工程管理的有效方略,旨在提高我国环境污染治理工程管理水平。     

环境空气质量自动监测站的管理与维护

随着工业化、城镇化的深入推进,二氧化硫、氮氧化物、烟粉尘和挥发性有机物等各类污染物排放到环境中,致使中国大气受到严重污染,给人体的健康、动植物的生长、发育和繁殖等带来负面的影响。为实时监测环境空气质量,建立环境空气质量自动监测站逐渐成为大气污染防治的主要手段。文中以环境空气质量自动监测站为研究对象,提出环境空气质量自动监测站管理与维护面临的问题,探讨相应的解决措施,以期为环境空气质量自动监测站的管理与维护提供参考依据。     

基于安全度与运营格局的油库选址优先级评价方法研究

从安全性和运营角度对油库选址的影响因素及评价指标分析对油库的安全稳定及有效运营具有重要的意义。该文选取与安全和运营有关的人口企业数量、安全管理能力、消防设施规划、地形地质条件、铁路公路数量、市场投资收益、政策支持情况等影响因子进行重要性及合理程度分析,综合运用安全度与运营格局影响因素多元耦合关系,构建了油库区安全与运营评价体系,改进了原有的模糊层次法评价模型,并对某油库区安全度与运营格局进行了评估验证。结果表明:利用改进模糊层次法能够较好地评价不同地址的优先级,评价模型具有一定应用性,能够对不同地址的特点及评价权重进行有效分析,可见油库选址优先级评价方法是实用且有效的。该研究方法及结果可以为油库区地址的优选提供一定参考与建议。     

Metabolic diversity of the heterotrophic microorganisms and potential link to pollution of the Rouge River

The heterotrophic microbial communities of the Rouge River were tracked using Biolog Ecoplates to understand the metabolic diversity at different temporal and spatial scales, and potential link to river pollution. Site less impacted by anthrophogenic sources (site 1), showed markedly lower metabolic diversity. The only substrates that were utilized in the water samples were carbohydrates. Sites more impacted by anthrophogenic sources (sites 8 and 9) showed higher metabolic diversity. Higher functional diversity was linked to the physico-chemical and biological properties of the water samples (i.e. higher concentrations of DO, DOC, chlorophyll, and bacterial density). Biolog analysis was found to be useful in differentiating metabolic diversity between microbial communities; in determining factors that most influence the separation of communities; and in identifying which substrates were most utilized by the communities. It can also be used as an effective ecological indicator of changes in river function attributable to urbanization and pollution.     

不同种植方式对水生植物生长的影响

水生植物恢复是水体生态恢复与重建的一个关键,而人工快速大面积恢复沉水植物存在较大的难度。在淀山湖318国道近岸水域生态带内,运用水泥涵管覆土种植、箩筐覆土种植、纱布包裹覆土种植、编织袋覆土种植和竹签扦插法对水生植物进行种植。通过实验得出,运用水泥涵管覆土种植的芦苇存活率比用箩筐覆土种植的存活率高;运用水泥涵管覆土+竹签扦插法种植的狐尾藻存活率比其他几种种植方法的存活率高,几种种植方式下的生物量无显著差异。     

Enhancing consultation practices on Air Quality Management in local authorities

Schedule 11 of the Environment Act 1995 underpins the requirement for consultation on air quality issues. The ongoing air quality review and assessment process represents one of the largest locally based science policy and communication initiatives ever undertaken in the UK. This paper outlines the practice of consultation and communication for Air Quality Management (AQM) and reviews the interaction between Environmental Health professionals, as the leading actor in the AQM process and other stakeholders involved in air quality consultation, including the public. Results are presented from a widespread questionnaire survey of English local authorities. Data indicate that the majority of air quality consultation has been carried out with statutory consultees (by sending the review and assessment reports) and the public (via websites and leaflets) in the form of information dissemination.     

泰州市建设用地扩展规律与格局演化研究

以多时相Landsat、TM/ETM卫星影像为数据源,运用GIS软件提取泰州市建设用地1988～2008年5个时相的用地信息,运用扩展强度指数、扩展速度指数、空间自相关等方法分析泰州市建设用地扩展时空特征和演化规律。结果表明:(1)泰州建设用地扩展经历了缓慢扩展、中速扩展、缓慢扩展3个阶段,显示了建设用地逐步走向集约利用的趋势;(2)在分析泰州建设用地不同扩展阶段的基础上,发现泰州建设用地扩展模式正处于从点状扩展向点轴扩展转变阶段,并出现了网络化扩展的端倪;(3)运用空间自相关分析了泰州建设用地扩展热点演化过程,发现扩展热点呈现跳跃迁移的特征,热点区与冷点区出现交替演化,Moran散点图体现了泰州市建设用地扩展处于空间极化的状态,外围城镇受中心城镇增长极带动发展的扩展模式。     

Reduction of Baltic Sea Nutrient Inputs and Allocation of Abatement Costs Within the Baltic Sea Catchment

The Baltic Sea Action Plan (BSAP) requires tools to simulate effects and costs of various nutrient abatement strategies. Hierarchically connected databases and models of the entire catchment have been created to allow decision makers to view scenarios via the decision support system NEST. Increased intensity in agriculture in transient countries would result in increased nutrient loads to the Baltic Sea, particularly from Poland, the Baltic States, and Russia. Nutrient retentions are high, which means that the nutrient reduction goals of 135 000 tons N and 15 000 tons P, as formulated in the BSAP from 2007, correspond to a reduction in nutrient loadings to watersheds by 675 000 tons N and 158 000 tons P. A cost-minimization model was used to allocate nutrient reductions to measures and countries where the costs for reducing loads are low. The minimum annual cost to meet BSAP basin targets is estimated to 4.7 billion €.
