加快发展内河航运是国家交通重要发展战略,也是发展综合交通运输体系的必然要求。长期以来,我国内河运输船队装备落后、单耗高、污染重,不适应交通运输行业节能减排要求。重庆长江轮船公司作为中外运长航集团下属,专门从事长江干线集装箱运输的骨干企业,为转变发展方式,打造绿色航运,在集团总部的支持下,经过反复试验和科技攻关,研制成功了一批标准集装箱船,改善了公司船队结构、降低了集装箱运输燃油单耗、取得了显著的经济效益和节能减排效益。 相似文献

正当前,节能减排已成为我国一项基本国策,已成为我国调整经济结构、转变发展方式的突破口和重要抓手。做好节能减排工作不仅是企业履行社会责任的需要,同时是企业实现可持续发展、提高核心竞争力的需要。节能减排与企业发展并不矛盾,通过"节能"可以降低消耗成本、提高生产效率,通过"减排"可以调整优化产业结构、发展新生经济。但由于节能减排工作是一个系统性、综合性很强的工作,开发和应用节能减排技术和装备仅仅是节能减排工作的一个方面。通过建立、运行和改进 相似文献

This paper studies to what extent the Logsum-measure of user benefits relates to travelers’ perceptions of choice set-desirability and choice-satisfaction. Knowing these relations is important since researchers have recently started to analyze and interpret user benefits in general – and Logsums in specific – in terms of these more behaviorally oriented notions, rather than in terms of expected utility. Participants to a stated route choice experiment were asked to indicate, after each choice made, to what extent they considered the choice set to be desirable, or to what extent they were satisfied with the chosen alternative. These measurements were correlated with Logsums that were computed for each choice situation. In addition, the paper derives a regret-based Logsum (which gives the expected regret of a choice situation) and presents a comparison with its utilitarian counterpart. Also for this regret-based Logsum, correlations with desirability- and satisfaction-ratings are computed. As a general finding, it appears that all computed correlations are rather weak. This suggests that, at least in the context of our data, the utility-based Logsum and its regret-based counterpart appear to have only a fairly weak connection with the behavioral notions of choice set-desirability and choice-satisfaction. 相似文献

通过研究汽车与船舶的油耗特点,结合燃油种类与CO_2排放量的关系,建立了计算公路运输与水路运输单位耗油量与单位CO_2排放量的数学模型。通过敏感性分析,研究车速或航速与载货率对车辆或船舶单位CO_2排放量的影响。以从厦门港到盐田港的干散货运输为例,做了节能减排计算分析,并将结果与用其他方法获得的结果对比。在此基础上,对公路运输与水路运输节能减排做了敏感性分析研究,可以计算出能够体现水路运输节能减排优势的临界货运量。结果表明本文中介绍的方法能够为核算、比较公路运输与水路运输的节能减排效果提供更科学的量化参考。 相似文献

Recent years have shown a rising popularity of the concept of resilience—both theoretically and empirically—in complex systems analysis. There is also a rising literature on resilience in the transport and spatial-economic field. The pluriform interpretation of resilience (e.g., engineering vs. ecological resilience) is related to methodological differences (e.g., stability in dynamics vs. evolutionary adaptivity). But in all cases the fundamental question is whether a complex system that is subjected to an external shock is able to recover, and if so, to which extent. The present paper [Based on presentation from cluster 6 (Accessibility) of the Nectar 2015 conference in Ann Arbour, USA.] aims to add a new dimension to resilience analysis in spatial systems, by addressing in particular the relationship between spatial accessibility at a municipality level and the resilience outcomes of the spatial system concerned. It does so by investigating to which extent accessibility of Swedish and Dutch municipalities has mitigated the local shock absorption from the recent economic recession. In our study the shock absorption capacity of municipal accessibility is estimated by analysing the relevant resilience indicators for the period concerned. In this context, conventional resilience indicators based on either multivariate complex data (in particular, the Foster Resilience Capacity Index) or employment data (in particular, the Martin Resilience-Employment Index) are confronted with spatial connectivity data based on local accessibility measures, so that geographical mobility may be regarded as one of the shock-mitigating factors. The empirical analysis is carried out for two countries which have both proven to be rather shock-resistant during the recent economic crisis, viz. Sweden and The Netherlands. Clearly, the geographical structure of these countries forms a sharp mutual contrast, viz. a spatially dispersed economy with a few distinct urban concentrations versus a spatially dense economy with one major metropolitan centre (the Randstad), respectively. Our experiments are carried out for the 290 municipalities in Sweden and 40 COROPs in The Netherlands. Our research findings show relevant and new insights into differences in the local recovery potential in Sweden and The Netherlands. 相似文献
