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

美国的“页岩气革命”对世界能源走势产生了重大影响,作为清洁、高效的非常规油气资源,其成为低碳经济背景下能源消费大国趋之若鹜的目标。对此局势的战略性跟进,中国需保持清醒与冷静。根据循环经济和资源综合开发的要求,目前宜优先发展煤层气(瓦斯)。对于页岩气产业,应补贴勘探和技术研发,先做好页岩气资源的战略性储备工作。 相似文献

页岩气勘探开发场地的潜在污染风险不同于普通场地,而针对页岩气开发全过程的场地土壤地下水污染风险评价研究较为薄弱。文章综述了污染场地风险评价的理论与方法,介绍了岩溶介质地下水及溶 质运移模拟的研究进展,指出由于页岩气开发场地的复杂性,基于污染物在土壤地下水系统迁移的过程模拟法(考虑岩溶通道)较适用于页岩气开发全过程污染风险评价,强调应加强页岩气开发不同生产阶段土壤、地下水 污染监测,拓展风险评价指标筛选的理论与方法。同时,应强化岩溶通道及裂隙相关参数的获取,并开展土壤-地下水耦合评价及页岩气开发全过程(勘探—钻井—压裂返排—生产)风险评价,为页岩气绿色开发提供理论指导。 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

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 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
