Developing a Regional Open Space Strategy (ROSS) for Central Puget Sound,Washington State,USA

Ecosystem services provided by the landscapes of regions and cities are critical to human and environmental health, quality of life, environmental justice, biodiversity and climate mitigation and adaptation. In the Pacific Northwest region of the US, a team led by the University of Washington Green Futures Lab is working to identify, conserve and enhance regionally-significant landscapes and to evaluate their contributions as ecosystem or “open space” services. This paper outlines the goals and planning methods of the ongoing Regional Open Space Strategy for Central Puget Sound (ROSS) project, and the frameworks and processes being developed to evaluate ecosystem and open space services in order to inform and influence local and regional governance structures and decisions.     

在较高位置构筑大型隔声屏的降噪工程

在控制工厂二层楼顶的风机群及冷却塔群的噪声工程中，复式隔声屏获１８ｄＢ（Ａ）的降噪效果。主屏由轻结构板及隔振底盘组成。主习体被若干伸缩隔断以消除热应力。副屏是为了减少主屏隔振底盘缝的漏声。迷路消声构造减少伸缩缝的漏声。为了抗风，主习必须锚固，并且屏体自身应有良好的结构。

Prevention of railway trespassing by automatic sound warning—A pilot study

Objective: The objective of this study was to investigate the effects of a sound warning system on the frequency of trespassing at 2 pilot test sites in Finland.

Methods: The effect of automatic prerecorded sound warning on the prevention of railway trespassing was evaluated based on observations at 2 test sites in Finland. At both sites an illegal footpath crossed the railway, and the average daily number of trespassers before implementation of the measures was about 18 at both sites.

Results: The results showed that trespassing was reduced at these sites by 18 and 44%, respectively. Because of the lack of proper control sites, it is possible that the real effects of the measure are somewhat smaller.

Conclusions: The current study concludes that automatic sound warning may be efficient and cost effective at locations where fencing is not a viable option. However, it is not likely to be a cost-effective panacea for all kinds of sites where trespassing occurs, especially in countries like Finland where trespassing is scattered along the railway network rather than concentrated to a limited number of sites.

Stream corridor management in the Pacific Northwest: I. Determination of stream-corridor widths

King County, Washington is a part of the rapidly growing Pacific Northwest region. This growth has placed pressure on stream corridors. Past studies about regional stream corridors provide a rich source of information for environmental planners and managers. This article draws on existing literature and case studies to provide guidelines for determining optimal stream corridor widths in a watershed located in King County, Washington.     

3R strategies for the establishment of an international sound material-cycle society

Focusing on the promotion of the “3Rs” – reduce, reuse, and recycle – the authors summarize the policy that Japan has evolved in waste management and recycling policy over the years. To realize an international sound material-cycle society (SMS), the 3R approaches should first be implemented in each individual country. After each country has established an SMS to the best of its ability, contribution toward reducing the environmental load internationally, especially across all of East Asia, will be achieved by having waste and recyclable resources that cannot be handled in one country effectively used or processed in other countries. The current situation of international resource circulation is described and a concept of SMS at an international level is proposed.
