KTV、慢摇吧等娱乐场所噪声治理方法研究

近年来,随着KTV,慢摇吧等娱乐场所的增加,娱乐场所带来的噪声扰民问题也日益突出。由于业主、施工单位等缺乏隔声降噪的专业知识,使得这一问题没有很好解决。本文通过对这类噪声的特性分析,根据其具有低频为主、穿透力强、不易衰减等特点,结合工程实例,从提高顶棚、侧墙的隔声量,结构上多采用弹性连接及增加阻尼等角度提出几点治理方法。以隔声、隔振为主,控制这类噪声通过空气传声与固体传声等途径向周围居民区传播。

Public Participation as Participatory Communication in Environmental Policy Decision-Making: From Concepts to Structured Conversations

This essay attempts to distinguish between traditional notions of public participation and participatory communication, particularly as currently practiced in non-US settings. In addition, specific tools for facilitating participatory communication are identified and discussed. The essay is based on the author's extensive experience as a conflict mediator and public participation consultant and scholar. For the past 15 years, the author has served as a consultant on matters of environmental conflict resolution, public participation, and community-based collaboration for federal and state agencies and NGOs, including the USDA Forest Service, the USDI Bureau of Land Management, the US Army Corps of Engineers, the Washington Department of Fish and Wildlife, the Oregon Department of Environmental Quality, and the Nature Conservancy.     

The Clean Development Mechanism and Sustainable Development in China's Electricity Sector

Abstract

The Clean Development Mechanism, a flexibility mechanism contained in the Kyoto Protocol, offers China an important tool to attract investment in clean energy technology and processes into its electricity sector. The Chinese electricity sector places centrally in the country's economy and environment, being a significant contributor to the acid rain and air pollution problems that plague many of China's cities and regions, and therefore a focus of many related energy and environmental policies. China's electricity sector has also been the subject of a number of economic analyses that have showed that it contains the highest potential for clean energy investment through the Clean Development Mechanism of any economic sector in China. This mechanism, through the active participation from investors in more industrialized countries, can help alleviate the environmental problems attributable to electricity generation in China through advancing such technology as wind electricity generation, clean coal technology, high efficient natural gas electricity generation, or utilization of coal mine methane. In this context, the Clean Development Mechanism also compliments a range of environmental and energy policies which are strategizing to encourage the sustainable development of China's economy.     

环境审计制度选择影响因素的实证分析

随着环境问题的日益严重,污染治理工具的选择和实施成为社会各界普遍关注的焦点.本文选择150个国家的国别数据,采取logit模型对环境审计制度选择的影响因素进行分析.研究结果表明,经济发展水平、环境保护投资和社会信息化程度与一国是否开展环境审计成显著正相关;审计体制对环境审计的开展也具有显著性影响;而污染排放现状、邻国的决策对环境审计制度选择的影响并不显著.本文的研究表明,与传统命令——控制型规制工具的普适性不同,作为一种信息化的污染治理工具,环境审计是经济社会发展到一定阶段国家最高审计机关的选择.进一步,利用我国2007年-2011年的相关数据进行基于主成分回归的符合性检验,结果显示环境审计的概率值p皆高于50％,且逐年递增,表明我国现阶段实施环境审计的条件和时机已经基本成熟.本文的研究发现为我国最高审计机关“十二五”期间将环境审计作为一种独立的审计类型,在全国推行环境审计工作提供了理论依据.     

The Belt and Road Initiative and the 2030 Agenda for Sustainable Development: seeking linkages for global environmental governance

ABSTRACT

Global environmental cooperation serves as an important part in the Chinese ideal of building a Community with a Shared Future for all Human Beings. The report of 19th CPC National Congress indicates that China is committed to proactive mitigation under the Paris Agreement and further participating in global environmental governance under the 2030 Agenda for Sustainable Development, and both of which are largely integrated to the Belt and Road Initiative (BRI). BRI are also closely linked with South–South environmental and climate cooperation proposed by China from previous UN summits. Based on shared ideas, intersected agendas, and compatible governance approaches, BRI and the 2030 Agenda for Sustainable Development grow increasingly relevant and they might form synergies based on increasingly interactive relations. In sum, seeking and intensifying the linkages between BRI and 2030 sustainable development goals (SDGs) could address global environmental governance deficits and enhance cooperation among nations.     

风蚀扬尘抑尘剂效率测试方法与应用

风蚀扬尘抑尘剂是一种控制风蚀扬尘的有效措施,探讨使用便携式风洞(PI-SWERL)测试风蚀扬尘抑尘剂效率的方法,并对比国内外2种抑尘剂对风蚀扬尘PM2. 5的抑制效率,以研究喷洒方式、稀释倍数和风速对抑尘效率的影响.结果表明:①按照推荐的稀释倍数分别配置G和Enviroseal(ES)抑尘剂水溶液并测试,液滴喷洒方式对应的抑尘效率优于雾化喷洒方式,在17. 2 m·s~(-1)(相当于8级风)风速时G抑尘剂效率(99. 5%)优于ES抑尘剂(94. 0%)和水(77. 5%);②对稀释倍数为50、100、150、200和400倍的G抑尘剂进行测试,在17. 2 m·s~(-1)风速时,抑尘效率分别为99. 7%、99. 5%、99. 7%、98. 1%和95. 9%,可根据抑尘效率变化拐点确定抑尘剂最佳成本效益稀释倍数;在13. 1～17. 2 m·s~(-1)风速范围内,抑尘效率随风速增加而增加.③使用便携式风洞测试风蚀扬尘抑尘剂效率的方法,可以量化抑尘剂对风蚀扬尘PM2. 5的抑制效率,建议对风蚀扬尘抑尘剂开展抑尘有效期和环境友好性测试.     

Minimizing external indirect health costs due to aerosol population exposure: a case study from Northern Italy

Environmental Agencies require Decision Support Systems, in order to plan Air Quality Policies considering the cost of emission reduction measures and the human health effects (with related social costs). The use of Decision Support Systems is also useful to spread information to general public, explaining the effectiveness of proposed air quality plans. In this paper, a multi-objective approach to control PM10 concentration at a regional level is presented. The problem considers both the internal costs (due to the implementation of emission reduction measures) and the external costs (due to population exposure to high PM10 concentrations). To model PM10 concentrations, a single surrogate model is used for the entire domain, allowing the implementation of a very efficient optimization procedure. The surrogate model is derived through a set of 10 simulations, performed using a Chemistry Transport Model fed with different emission reduction scenarios. The methodology is applied to Northern Italy, a region affected by very high PM10 concentrations that exceed the limit values specified by the EU legislation.
