我国PM2.5监测网络布局与监测方法体系构建策略分析   总被引:3,自引:0,他引:3  
本文通过对国内外PM2.5监测网络布局现状的分析和比较,认为我国"十二五"规划的PM2.5监测网络在点位数目和网络布局上基本能够反映我国PM2.5污染状况。为进一步反映PM2.5的污染特征和来源,今后应逐步增加污染监控点位、道路交通点位的设置,并在质量浓度监测的基础上,逐步开展PM2.5主要组分监测。在监测方法选择上,β射线法联用动态加热系统(DHS)PM2.5自动监测仪器和振荡天平法联用膜动态测量系统(FDMS)PM2.5自动监测仪器均能够满足监测工作的需要,综合考虑两种类型仪器的性能指标和运行成本,β射线法联用动态加热系统(DHS)PM2.5自动监测仪器操作相对简单,运行维护成本相对较低,更适合在我国环境空气监测网络内推广和普及。  相似文献

There is a critical need to collectively understand, to develop adaptation options to enhance the benefits, and to reduce the social and economic vulnerabilities induced by climate variability and change. This paper uses key questions to help build a framework for adaptation by first organizing the questions into adaptation science, management and option components, including their respective sub-categories. The process of adaptation depends on many factors, including who or what adapts, what they adapt to, how they adapt and what and how resources are used. This conceptual model is designed to organize concepts regarding adaptation, to help stimulate ideas, and to explore the linkages among parts of the adaptation cycle. Predictive models need to be developed to determine the outcomes of planned adaptation strategies. For the best and most realistic evaluation of climate problems, adaptation and impacts should be considered together. This joint approach improves the assessment of the significance and dangers of the current and future climate, as well as the determination of solutions (e.g., how to prepare for a changing climate) and their priorities. Challenges of adaptive management are discussed in terms of a framework with linkages to adaptation science and options. Adaptation research and applications work continue to build on the foundation of science and management frameworks to address the risks and uncertainties in the decision-making process and to identify adaptation options.  相似文献

Climate change potentially brings continuous and unpredictable changes in weather patterns. Consequently, it calls for institutions that promote the adaptive capacity of society and allow society to modify its institutions at a rate commensurate with the rate of environmental change. Institutions, traditionally conservative and reactive, will now have to support social actors to proactively respond through planned processes and deliberate steps, but also through cherishing and encouraging spontaneous and autonomous change, as well as allowing for institutional redesign. This paper addresses the question: How can the inherent characteristics of institutions to stimulate the capacity of society to adapt to climate change from local through to national level be assessed? On the basis of a literature review and several brainstorm sessions, this paper presents six dimensions: Variety, learning capacity, room for autonomous change, leadership, availability of resources and fair governance. These dimensions and their 22 criteria form the Adaptive Capacity Wheel. This wheel can help academics and social actors to assess if institutions stimulate the adaptive capacity of society to respond to climate change; and to focus on whether and how institutions need to be redesigned. This paper also briefly demonstrates the application of this Adaptive Capacity Wheel to different institutions.  相似文献

N和P对东海中北部浮游植物的影响研究   总被引:4,自引:0,他引:4  
调查海域浮游植物种类丰富,海水富营养化趋势明显.采用通径方法分析2001~2003年春夏季数据,在众多环境因子中,N、P含量及其组成与浮游植物关系最为密切,是影响浮游植物的数量和种类组成变化的首要因子.硅藻和甲藻对各种N的利用能力不同,是硅藻在调查海域占据绝对优势的重要原因;在同一季节中,硅藻和甲藻利用不同层次的氮盐,减少了两者间的竞争压力.高NO3-N/TIP对某些种类具有抑制作用,对甲藻而言,这种抑制作用更为明显.NO3-N/TIP在10~20、NH4-N/TIP或NO2-N/TIP小于1时,浮游植物的多样性最为丰富.NO2-N/TIP对硅藻的种类数变化几乎没有影响,而与甲藻的种类数成正相关.  相似文献

There have been many calls in policy and academia for more inclusiveness in science-policy interfaces, but there is as yet insufficient clarity as to what such inclusiveness means and how to achieve it in the context of international organisations. This paper analyses how inclusive the IPCC is across geographies and stakeholders. Building on the distinction between access and active participation, it examines the involvement of developing countries and NGOs in the Panel’s assessment process.The analysis shows that more inclusive institutional set-ups in international science-policy organisations do not automatically lead to greater credibility, salience and legitimacy of knowledge production processes (Mitchell et al., 2006). For instance, inclusive access does not per se guarantee active participation as the latter depends on a variety of factors including resources and the capacity of actors to engage. Furthermore, in institutional contexts the idea of inclusiveness is necessarily subject to operational interpretations. How these interpretations relate to the representativeness of those who participate in the process affects the relevance of knowledge to its users’ needs. Finally, there are political elements to inclusiveness as more powerful actors may be unwilling to renegotiate the balance of power to expand access to stakeholders.The paper concludes that these nuances should be taken into account in the IPCC and other international science-policy institutions. It also urges the Panel to address the developing country participation gap and explore institutional avenues for expanding access to non-state stakeholders in order to increase the credibility, salience and legitimacy of its processes and shift to solutions-oriented assessments.  相似文献

Climate change is expected to adversely affect agricultural production in Africa. Because agricultural production remains the main source of income for most rural communities in the region, adaptation of the agricultural sector is imperative to protect the livelihoods of the poor and to ensure food security. A better understanding of farmers’ perceptions of climate change, ongoing adaptation measures, and the decision-making process is important to inform policies aimed at promoting successful adaptation strategies for the agricultural sector. Using data from a survey of 1800 farm households in South Africa and Ethiopia, this study presents the adaptation strategies used by farmers in both countries and analyzes the factors influencing the decision to adapt. We find that the most common adaptation strategies include: use of different crops or crop varieties, planting trees, soil conservation, changing planting dates, and irrigation. However, despite having perceived changes in temperature and rainfall, a large percentage of farmers did not make any adjustments to their farming practices. The main barriers to adaptation cited by farmers were lack of access to credit in South Africa and lack of access to land, information, and credit in Ethiopia. A probit model is used to examine the factors influencing farmers’ decision to adapt to perceived climate changes. Factors influencing farmers’ decision to adapt include wealth, and access to extension, credit, and climate information in Ethiopia; and wealth, government farm support, and access to fertile land and credit in South Africa. Using a pooled dataset, an analysis of the factors affecting the decision to adapt to perceived climate change across both countries reveals that farmers were more likely to adapt if they had access to extension, credit, and land. Food aid, extension services, and information on climate change were found to facilitate adaptation among the poorest farmers. We conclude that policy-makers must create an enabling environment to support adaptation by increasing access to information, credit and markets, and make a particular effort to reach small-scale subsistence farmers, with limited resources to confront climate change.  相似文献

How conservation messages are framed will impact the success of our efforts to engage people in conservation action. This is highly relevant in the private land conservation (PLC) sector given the low participation rates of landholders. Using a case study of PLC schemes targeted at Australian landholders, we present the first systematic analysis of communication strategies used by organisations and government departments delivering those schemes to engage the public. We develop a novel approach for analysing the framing of conservation messages that codes the stated benefits of schemes according to value orientation. We categorised the benefits as flowing to either the landholder, to society, or to the environment, corresponding to the egoistic, altruistic and biospheric value orientations that have been shown to influence human behaviour. We find that messages are biased towards environmental benefits. Surprisingly, this is the case even for market-based schemes that have the explicit objective of appealing to production-focussed landholders and those who are not already involved in conservation. The risk is that PLC schemes framed in this way will fail to engage more egoistically oriented landholders and are only likely to appeal to those likely to already be conservation-minded. By understanding the frame in which PLC benefits are communicated, we can begin to understand the types of people who may be engaged by these messages, and who may not be. Results suggest that the framing of the communications for many schemes could be broadened to appeal to a more diverse group (and thus ultimately to a larger group) of landholders.  相似文献
