我国页岩气开发环境保护面临的形势及对策 总被引:5,自引:5,他引:0
页岩气作为一种重要的非常规新能源,已成为我国油气"十三五"规划的重点目标之一。文章借鉴美国、加拿大和欧洲多国的页岩气开发经验和教训,指出页岩气开发过程存在的生态破坏、水污染、甲烷泄漏、噪声污染、固体污染等潜在环境风险。压裂取水对区域生态环境和水资源的影响、压裂返排液对地下水环境的潜在影响、危险废物废弃油基泥浆和油基钻屑的环境风险等对我国页岩气可持续发展提出严峻考验。为此,我国相关部门正在加快相关环保技术研究、环保法律法规和标准规范的制定、实施战略环境影响评价等工作,逐步加强对页岩气开发过程的环境监管,完善全过程监管体制。 相似文献

随着社会和国民经济的发展,我国对能源的需求量不断增加。美国"页岩气革命"使页岩气作为一种新型清洁高效的非常规能源出现并受到了广泛关注。页岩气的开发有助于改善和保障我国能源结构和安全,因此我国也相继投入到页岩气的勘探开发热潮中。据探明,四川盆地页岩气储量丰富,宜宾市恰好处于有利开发区,已被国家列为先导试验区,拟为页岩气的滚动开发积累经验。但目前对这一新兴行业尚缺乏科学、系统的行政管理和环境监管等法规体系,先行开发过程中难免面临一系列的生态破坏和环境影响等问题。针对当前全国试验区开发的形势,在宜宾市页岩气开发的现实基础上,系统分析了这些问题并提出了对策与建议,旨在为后续页岩气的可持续开发和环境管理与保护工作提供一些参考。 相似文献

ABSTRACTThe exploration and potential extraction of shale gas – better known as fracking – has emerged as one of the most contentious dimensions to local environmental politics in the UK. Local residents and environmental activists have raised concerns about health, noise, ground water contamination, seismicity, environmental amenity, and other impacts of the industry on communities. Despite the complexities of shale gas extraction, an emphasis on the local has shaped key dimensions of the debate around the appropriate location for well pads to the relative exclusion of other issues. This paper draws on fieldwork in Lancashire, UK, to reflect on the political construction of scale in order to explore how an emphasis on “the local” can restrict political debate over shale gas to narrow concerns with land-use planning thereby obviating a fuller engagement with wider questions concerning risk, energy policy, and climate change. It is concluded that a more nuanced conception of scale is necessary for understanding how concerns with shale gas are diminished rather than strengthened through the current planning policy and regulatory regime operating in the UK. 相似文献

The use of best management practices to respond to externalities from developing shale gas resources
Terence J. Centner Nicholas S. Eberhart 《Journal of Environmental Planning and Management》2016,59(4):746-768
The public is concerned that activities accompanying hydraulic fracturing in the development of shale gas resources are unnecessarily adversely affecting them and the environment and is petitioning elected representatives to take actions to reduce risks. The health risks associated with fracturing chemicals and air pollutants are relatively unknown and constitute the impetus for public concern. An evaluation of state legal and regulatory provisions regarding best management practices discloses that states are not adopting timely regulations to protect people and the environment from activities accompanying hydraulic fracturing. Simultaneously, regulatory policy concerning negative externalities suggests that governments underinvest in the protection of human health and environmental quality. Governments have choices in protecting people from dangers that accompany shale gas development. Due to the risks of injuries and unpaid damages from shale gas development, governmental policies need to evolve to accord people greater health protection. 相似文献

The exploitation of shale gas resources is a significant issue of environmental justice. Uneven distributions of risks and social impacts to local site communities must be balanced against the economic benefits to gas users and developers; and unequal decision-making powers must be negotiated between local and central governments, communities and fracking site developers. These distributive and procedural elements are addressed in relation to UK policy, planning, regulatory and industry development. I adopt an explicitly normative framework of policy evaluation, addressing a research gap on the ethics of shale gas by operationalising Shrader-Frechette’s Principle of Prima Facie Political Equality. I conclude that UK fracking policy reveals inherent contradictions of environmental justice in relation to the Conservative Government’s localist and planning reform agendas. Early fracking policy protected communities from harm in the wake of seismic risk events, but these were quickly replaced with pro-industry economic stimulation and planning legislation that curtailed community empowerment in fracking decision-making, increased environmental risks to communities, transferred powers from local to central government and created the conditions of distributive injustices in the management of community benefit provisions. I argue that only by “re-localising” the scale of fracking governance can political equality be ensured and the distributive and procedural environmental injustices be ameliorated. 相似文献

Despite enthusiasm about new gas reserves, shale gas has not come to Poland without controversies. This study examines how shale gas has been framed as a public issue by political and business elites, experts, local communities and civil society organizations. Through a frame analysis, we found three main frames about shale gas: shale gas as a novel economic resource, as a strategic resource for energy security and as a threat. However, only the first two frames, proposed by political and business elites, have shaped the policy process. The third frame, constructed by local actors and civil society groups, has had minimal impact. We explain this exclusion drawing on the deficit model of risk communication. This approach reveals that Polish experts, and business and political actors, during their interactions with local groups, have framed proponents of the threat frame as ‘incompetent actors’ effectively excluding the threat frame from policy processes. 相似文献

Based on semi-structured interviews with 31 Ohioans, this article argues that individuals who are concerned about shale energy development draw from a discursive framework that diverges dramatically from the position promoted by industrial proponents. While the oil and gas industry and its supporters largely embrace a neoliberal outlook that most closely correlates well-being with economic growth, citizens troubled by such development are guided by a more holistic perspective that links well-being to numerous interrelated non-economic elements including human health, community continuity, political empowerment, and environmental sustainability. This work contributes to an emerging understanding of how environmental change and socionatural well-being converge in the novel context of shale energy development and aims to give voice to those who cope with the direct consequences of twenty-first-century fossil fuel extraction. Approaching discourse – defined here as shared communication patterns that simultaneously reproduce and generate distinctive understandings of the world – as a dynamic arena of sociopolitical struggle, I further suggest that shale energy opponents use holistic sustainability discourse to actively or implicitly challenge neoliberal strategies for guiding thought and governing action. 相似文献

We propose a framework to facilitate the evaluation of the impacts of shale gas infrastructures (well pads, roads, and pipelines) on land cover features, especially with regards to forest fragmentation. We used a geographic information system and realistic development scenarios largely inspired by the PA (United States) experience, but adapted to a region of QC (Canada) with an already fragmented forest cover and a high gas potential. The scenario with the greatest impact results from development limited by regulatory constraints only, with no access to private roads for connecting well pads to the public road network. The scenario with the lowest impact additionally integrates ecological constraints (deer yards, maple woodlots, and wetlands). Overall the differences between these two scenarios are relatively minor, with <1 % of the forest cover lost in each case. However, large areas of core forests would be lost in both scenarios and the number of forest patches would increase by 13–21 % due to fragmentation. The pipeline network would have a much greater footprint on the land cover than access roads. Using data acquired since the beginning of the shale gas industry, we show that it is possible, within a reasonable time frame, to produce a robust assessment of the impacts of shale gas extraction. The framework we propose could easily be applied to other contexts or jurisdictions. 相似文献
