两型社会的综合评价研究   总被引:1,自引:0,他引:1  
在熵模糊物元分析的基础上,结合模糊集合理论和欧式贴近度的概念,建立了资源节约型、环境友好型社会建设进程的综合评价模型,并以青岛市的资源节约型、环境友好型社会的建设进程监测为例进行了实证分析.该模型将资源节约型、环境友好型社会建设进程中各待评年度的资源节约和环境友好能力作为物元,在计算欧式贴近度时,采用熵值法确定权重系数.计算结果表明,该模型方法能够有效实现对青岛市2004 - 2009年度资源节约型、环境友好型社会建设进程及能力状况的识别与排序,评价结果与实际情况吻合较好,表明熵模糊物元分析方法合理、可行.  相似文献

海河流域社会经济发展对河流水质的影响   总被引:5,自引:2,他引:3

海河流域社会经济快速发展,主要河流水质恶化.本文基于海河流域人口规模、经济产值和土地利用变化过程,结合河流社会经济发展指标和水质变化统计分析,从流域废污水排放和水资源利用等角度分析社会经济对水环境影响机制.研究表明,流域人口规模大幅增长、工业生产强度大幅提高,工业聚集区由北京-天津地区扩展到北京-天津-唐山、石家庄、聊城-德州等地区,导致海河流域工业废水和生活污水排放规模迅速上升,成为河流水质恶化直接驱动力.城市扩张是流域土地利用变化最显著特征,近30年来城市用地面积增加85%,北京-天津-唐山城市群规模扩大,造成流域水资源开发利强度加剧,降低河流自净缓冲能力.因子分析表明,流域影响河流水质因素分解为农村、城市和自然等3个方面,其中城市化过程和农村社会经济发展对河流水体污染物浓度水平影响非常显著.  相似文献

This paper focuses on impediments to environmentally sound management practices and how these might be overcome, with an emphasis on the role of environmental management systems, supply chains and civil society. It argues that: Farmers are under increased pressure to cut costs and improve production but with little opportunity to increase prices. Commonly short-term economic interest has damaging environmental implications. Current government policy, in Australia and in many other jurisdictions, relies heavily on voluntary arrangements, education and information, as the main policy instruments through which to persuade farmers to adopt better environmental farm management - e.g. the recent push to encourage the use of voluntary environmental management systems. However, there is good evidence to suggest that these can only make a valuable contribution when combined with a range of other policy instruments, including positive and negative incentives, intervention by third parties and in some cases, an underpinning of regulation. Arguably, what is needed is a strategy that builds on the strengths of voluntary environmental management arrangements while compensating for their weaknesses by combining them with other, complementary policy instruments. If so, we must engage with a range of questions that have not so far figured substantially in the policy debate. Although the principal focus has been on the role of government in bringing about on-farm change in management practices, supply chain pressure (at least in respect of agricultural chemicals and practices which threaten food safety) and civil society action are also potentially powerful mechanisms for bringing about change. Government can and should play a role in harnessing such forces in the interests of improved environmental on-farm practices.  相似文献

风险社会中突发事件的特征与处置理念探析   总被引:3,自引:0,他引:3  
突发性事件由于其本身所具有突发性、紧急性、危重性、复杂性、关联性、广泛性、政治性和不确定性等特征,所以其负面性影响很大,往往可能成为激发社会矛盾、进而爆发政治、经济和社会危机的直接原因。而经济转轨、社会转型、利益群体多元化等许多不稳定的因素,对局部地区乃至全国的经济发展和社会稳定构成了潜在威胁。在这样一个具有诸多风险因素的社会,由此而引发的突发事件又有形式多元化、规模扩大化、形态群体化、影响辐射化、目标国际化等特点。所以,在现阶段,处置突发事件的理念必须适应这种风险社会的公共危机特点,做到危机缓和,未病先防;以人为本,取信于民;利益调和,治病求本。  相似文献

The social and economic implications of atmospheric change on biodiversity need to be seen in a global context of major shifts in the conceptualization and management of our relationship with nature. Traditionally, we have conceptualized the atmosphere and the other creatures of the biosphere as separate from the human, but their quasi-autonomy is now becoming subject to more and more human management. This raises not only economic issues, but social, political, and ethical concerns that will have substantial influence on public policy. Among these are the commodification of genetic material; the privatization of traditional knowledge; and the management of information. In this broader context, the paper examines an array of current and proposed strategies of response to changes in biodiversity as a result of climatic and other stresses.  相似文献

Monitoring Sustainable Forest Management in Different Jurisdictions   总被引:1,自引:0,他引:1  
The concept of sustainable forest management (SFM) requires forest resource managers to monitor and collect information pertaining to their environmental, economic and social impact. There are increasing expectations from a variety of publics (government, customers, and other stakeholders) that forests be demonstrably well-managed, creating incentives for forest managers to design credible systems for assessing their management performance. It is against this background that local, national and international approaches to regulating forest practices have been evolving. This article reviews the different dimensions of governance as they relate to monitoring and information reporting in the forest sector. Specifically, it discusses the changing role of sovereignty, the effects of globalization and the emergence of civil society stakeholders in forestry-related decision-making. Concepts such as sovereignty and globalization have important implications for monitoring forest practices and for defining SFM. Whether SFM standard creation and enforcement involves a sovereign, shared-sovereignty or civil society approach will affect the level and nature of SFM monitoring. As a result, we need to better consider the concept of monitoring appropriate to the scale and intensity of operations, how monitoring and information reporting standards differ between jurisdictions, and what this means for independently verifying SFM at an inter-jurisdictional level.  相似文献
