油气生产与生态环境协调发展的对策建议

生态环境的可持续发展是制约我国经济社会可持续发展的一大"瓶颈"。我国石油工业的发展不可避免地对生态环境产生了一定的负面影响和破坏,在未来的发展过程中,应不断以创新的理念引领社会责任,加大环保力度,大力实施节能减排、清洁生产、安全生产和节约生产,扎实推进资源节约型、环境友好型企业建设,促进人与自然的和谐发展。

Biofuel policies and the environment: Do climate benefits warrant increased production from biofuel feedstocks?

We examine whether climate benefits warrant policies promoting biofuel production from agricultural crops when other environmental impacts are accounted for. We develop a general economic-ecological modelling framework for integrated analysis of biofuel policies. An economic model of farmers' decision making is combined with a biophysical model predicting the effects of farming practices on crop yields and relevant environmental impacts. They include GHG emissions over the life cycle, nitrogen and phosphorus runoff, and the quality of wildlife habitats. We apply our model to crop production in Finland. We find that under current biofuel production technology the case for promotion of biofuels is not as evident as has been generally thought. Only reed canary grass for biodiesel is unambiguously desirable, whereas biodiesel from rape seed and ethanol production from wheat and barley cause in most cases negative net impacts on the environment. Suggested policies in the US and the EU tend to improve slightly the environmental performance of biofuel production.     

The economic impact of shale gas extraction: A review of existing studies

Recent advances in drilling technology have allowed for the profitable extraction of natural gas from deep underground shale rock formations. Several reports sponsored by the gas industry have estimated the economic effects of the shale gas extraction on incomes, employment, and tax revenues. None of these reports has been published in an economics journal and therefore have not been subjected to the peer review process. Yet these reports may be influential to the formation of public policy. This commentary provides written reviews of several studies purporting to estimate the economic impact of gas extraction from shale beds. Due to questionable assumptions, the economic impacts estimated in these reports are very likely overstated.     

徐州离低碳城市有多远

城市是低碳经济、低碳产业的重要场所,也是低碳生活、低碳社会的重要载体,城市低碳是各国低碳转型、实现可持续发展的重要方面。根据低碳概念的历史沿革、低碳城市评估体系,从经济发展、能源消耗、生态环境、科技水平、二氧化碳排放等方面论述了徐州离低碳城市有多远。并在分析徐州的产业结构和能耗特征的基础上,提出徐州低碳城市建设的具体思路。     

基于低碳经济的我国产业体系构建研究

通过分析我国产业结构和能源结构变化趋势,计算第二产业、第三产业的二氧化碳排放量和二氧化碳排放强度,运用选取产业结构弹性指标对我国的第二产业、第三产业的比重与总体碳排放强度相关性进行估算,结果表明增加第三产业的比重同时减少第二产业比重具有减碳效应。     

250吨转炉静电除尘器稳定运行探讨

静电除尘器是一种高效的除尘器,已被越来越多的炼钢厂转炉所采用.为了保持静电除尘器长期、高效、稳定地运行,应该对影响静电除尘器除尘效率的因素进行分析,并加强对静电除尘器运行、维护和检修的管理.     

中国碳排放、经济增长与福利关系研究

对中国大陆1990—2007年人均碳排放、人均GDP以及人类发展水平进行单位根检验、协整检验以及格兰杰因果关系检验,结果表明:经济增长是碳排放与福利的单向格兰杰原因;碳排放和福利之间为双向因果关系;中国经济增长在突破生态门槛之后,又开始逼近福利门槛。     

基于“北斗一代”的Zigbee无线网关设计

为了解决野外多点数据采集无供电、布线复杂和通信困难的问题,提出了一种基于“北 斗一代”的Zigbee无线网关设计方案。采用MSP430F6438、CC2341微处理器和一体化的RDSS “北斗”射频芯片完成低功耗、小成本的硬件设计。通过增加SIM卡的数量,将网关转发“ 北斗”数据的频率降至最低的5 s,提高了网关的通信速率。通过软件设计实现了Zigbee无 线传感网络和“北斗一代”系统之间数据的透明交换。该方法已成功应用于野外油气井远程 监控系统中。
