重庆市环境质量自动监测(控)系统网络集成设计 总被引:5,自引:0,他引:5
针对目前重庆市环境空气质量自动监测现状,结合自动监控系统设计先进技术和国内部分省市已建成的环境信息监控网络的先进经验,对重庆市环境空气自动监测监控系统的建设进行设计,并介绍了环境空气质量自动监测监控系统的组成和实现的功能.现有的自动监测系统存在不同类型设备、通讯方式落后等问题,建设重庆市环境质量自动监控系统的思路是采用GPRS/CDMA/ADSL为主的数据通信传输技术,建立通信控制和信息集成系统,把重庆市环境空气、水、噪声自动监测系统进行系统化的集成,设计成一个完善的环境信息自动化动态监控平台. 相似文献

This article assesses the success of WWF Japan’s “Background Media Strategy” in influencing Japanese mainstream news outlets’ coverage of climate change negotiations. WWF Japan adopted this “Background Media Strategy” after the Bali COP in 2007; instead of lobbying, it aims to build journalists’ expertise. This article examines its success after seven years through three research approaches: the analysis of participant lists; two surveys (conducted in 2009 and 2015); and a content analysis of climate change articles that appeared in four large mainstream newspapers between April and July 2015. Based on these different data, the author concludes that the new media strategy was successful: Japanese journalists increasingly rely on information provided by WWF Japan and less on information provided by the government and industry. This experiment suggests that a new relationship between global NGOs and the media can improve environmental communications—an approach that could help advocacy groups around the world. 相似文献

近年来我们陆续承接了一些发展中国家电力工程中环境影响评价的招标,议标工作和世界银行(以下简称世行)在国内贷款项目的环境影响评价。本文就工作中所涉及的环境影响评价的深度和广度,执行标准,以及今后工作中有待加强的方面作了一些探讨。 相似文献

海平面上升及其带来的资源与环境问题是目前全球环境变化研究的核心问题之一。海平面上升分全球性理论海平面上升及区域相对海平面上升两类,前者与温室效应导致的海水表层受热膨胀、大陆高山及格陵兰地区冰川融化有关,后者更多起因于局部自然或人为造成的地面沉降及其他相关因素。研究海平面上升机理、过程,制定切实预防、预测措施,应引起广泛的社会关注。 相似文献

This paper tests an equilibrium condition from a model that incorporates: (1) altruism of parents toward their young children, and (2) household production of latent health risks. The model demonstrates that an altruistic parent's marginal rate of substitution between an environmental health risk to herself and to her child is equal to the ratio of marginal risk reduction costs. Econometric estimates support this prediction based on data from a stated preference survey involving 488 parents of children aged 3–12 years. This outcome implies that parents reallocate family resources to at least partly offset the effectiveness of public programs that aim to reduce their children's environmental risks. 相似文献

The planning and execution of water quality management programs requires careful collection and analysis of data coupled with a systematic review and analysis of programmatic success. The environmental audit is a tool which facilitates improved water quality planning and management. This article demonstrates the utility of the environmental audit by reviewing portions of a comprehensive review of the water quality management program for the state of Idaho. The audit is a tool which forces careful design of a sampling program before data are collected. In the audit approach, program objectives are clearly stated prior to initiation of sampling. Stated objectives are also evaluated regularly to identify tension points, that is, conflicts between expectations and reality. In the example taken from Idaho, a management review team followed a directive to redesign the water quality monitoring program. We present a summary of the redesign as proposed by that team, to illustrate the results of a typical review of monitoring programs. That summary is followed by an example of how the proposed program would differ if the audit approach had been used. The two approaches offered both coincident and conflicting recommendations. Management review team and audit recommendations for lake sampling programs were similar even though a different process was used to develop the recommendations. The most striking contrast between the two results lies in the review team's approach to the problem. The directives followed, and the team's responses, concentrate on tools, such as increasing biological monitoring or reliance on monthly BWMP stations. In contrast, the audit results stress addressing management questions for which clear objectives have been stated, depending on specific tools only as needed to meet stated objectives. Although the audit does integrate externalities in its structure, it is little affected by economic or political influences. A major strength of the audit approach is its ability to provide defensible data for management decision making. 相似文献

Estuaries and coastal lagoons are characterized by a strong spatial and temporal variability of physicochemical characteristics and productivity patterns. In these environments, the magnitude and direction of the ecological responses to inorganic nutrient increase (i.e. eutrophication) are difficult to predict. In the framework of the project, New Indicators of Trophic state and environmental quality of marine coastal ecosystems and transitional environments (NITIDA), we analysed benthic indicators of trophic state, ecosystem efficiency, and environmental quality in four different transitional environments. The trophic state of the sediments was assessed in terms of quantity and bioavailability of sediment organic C pools; ecosystem efficiency was determined in terms of the prokaryote efficiency in exploiting enzymatycally degraded organic C; environmental quality was determined in terms of meiofaunal diversity. Here, we provide a synopsis of the results obtained and a meta-analysis of the scores assessments obtained using the different ecological indicators of environmental quality and demonstrate that trophic state, ecosystem efficiency, and biodiversity in transitional ecosystems are closely linked. We conclude that the assessment of the environmental quality of transitional ecosystems should be based upon a battery of trophic state indicators and 'sensors' of ecosystem functioning, efficiency, and quality. 相似文献
