对城市污水处理工程管理的思考

城市污水处理工程建设，是保障水质的一个重要措施，是城市发展整体规划的重要绀成部分，也是建设循环经济、和谐文明、环境优美城市的迫切需要。城市污水处理工程管理包括工程可行性研究、设计、土建施工、设备选择、安装、调试和使用等环节管理。必须从优化工程设计抓施工图入手，掌握工艺流程，干好土 建工程，抓好设备安装和调试，并十分注意做好用户回访工作。文章对各环节质量管理存在的问题进行分析，提出了相应对策。

Communicating risk for issues that involve ‘uncertainty bias’: what can the Israeli case of water fluoridation teach us?

Water fluoridation is a controversial issue in public health. Despite the uncertainty regarding its efficacy and safety, health officials continue to communicate it as ‘unequivocally’ safe and effective. Our focus is on how health officials and policy-makers in Israel frame the issue of water fluoridation in terms of certainty while promoting a mandatory fluoridation policy. According to van Asselt and Vos, the uncertainty paradox describes situations in which uncertainty is acknowledged, but the role of science is framed as providing certainty. Our study is an analysis of documents and media articles emphasizing the paradoxical language used by official representatives on the controversial topic of fluoridation. A central contribution of this study is that we coin the term ‘uncertainty bias,’ in which policy-makers do exactly what they accuse laypeople of doing, framing uncertainty in biased terms. We found that in order to establish mandatory regulation, health ministry officials expressed information in an unbalanced format, promoting the topic of fluoridation by framing it in exclusively positive terms. This study does not focus on the practice of water fluoridation per se, and is not intended to decide for or against it, but rather, to explore how the debate regarding it is communicated. Understanding this particular case can shed light on how other controversial topics are transformed into health policy that is characterized in equivocal terms.

A game of give and take: The introduction of multi-layer (water) safety in the Netherlands and Flanders

At the beginning of the 21st century, the Netherlands and Flanders introduced a risk-based approach to flood risk management (FRM), labelled as multi-layer (water) safety. In contrast to a flood defence approach, risk-based management stresses the need to manage both the consequences and probability of a flood. The concept has developed differently in the two countries, as we conclude from a discursive-institutionalist research perspective. The Netherlands is characterised by a high institutionalization of the traditional flood defence discourse and a more closed policy arrangement, whereas in Flanders, the flood defence discourse is less institutionalized and the arrangement is more open. In both countries we see an opening of the arrangement preceding the establishment of multi-layer (water) safety, but at the same time, actors stress different aspects of the concept in order to increase its compatibility with the existing policy arrangement. In the Netherlands, the focus is on probability management, in Flanders on consequence management. In the Netherlands, multi-layer (water) safety as a concept could be established because it stabilises the system in the short-term by reinforcing the importance of flood defence, whereas in Flanders, policymakers were receptive to the concept because it supports a shift of responsibility towards actors outside traditional water management.     

水资源资产量核算研究综述

为了完善水资源资产负债表的编制以及提高水资源资产化管理水平,从水资源资产概念界定及其分类、水资源循环对水资源资产的影响、水资源资产账户与资产量核算方法 3个方面概述了国内外对水资源资产的研究进展、成果和方法。认为目前水资源资产的研究仍处于起步阶段,以概念探讨和定性分析为主;对水资源循环理论研究较多,对水资源资产的循环过程研究较少;对水资源资产量核算的研究主要集中在水资产账户方面,且系统性的研究较少。未来对水资源资产核算的研究应重点关注:水资源资产循环理论研究、潜在水资源资产量核算方法研究、区域水资源资产量核算方法研究等领域。

Natural and anthropogenic influences on the year-round temperature dynamics of air and water in Postojna show cave,Slovenia

Air and groundwater temperatures were measured in a rimstone pool in Postojna Cave, to advise evaluation of the impact of natural and anthropogenic influences related to heat being initially transmitted into cave air by visitors. Such heat can accumulate both in the rock mass and in water. Results show that attention must be paid to temperature changes of rimstone pool water rather than those of cave air, especially during the winter. Thanks to good ventilation deep inside the cave, short-term air temperature increases related to higher visitor numbers have not influenced flowstone precipitation or the cave fauna. However, this situation might change if winter visitor numbers increased greatly. This study does not support a suggested increase in winter visits (currently the tourism low-season) and reduction of summer visits (currently the tourism high-season).
