实物型水资源资产负债表表式结构设计

论文在阐述资产负债表基本概念和原理的基础上,遵循会计恒等式、复式记账规则和权责发生制的记账基础,结合我国水资源管理的实际,提出了基于会计学的水权益实体水资源资产负债表表式结构和基于统计学、经济学的国家（地区）水资源资产负债表表式结构,从而实现能够反映水权益实体之间和经济体与环境之间关于水资源资产的债务债权关系的水资源资产核算,实现国家和行政区层面的水资源资产负债核算,为生态文明体系建设、自然资源资产核算、领导干部离任审计考核等提供必要的基础信息,也为进一步完善水资源资产负债表账户体系奠定基础。     

基于水足迹理论的区域水资源利用评价

水资源是一个地区经济发展、社会稳定的基础。水资源利用评价研究对分析区域水资源问题、制定合理的水资源战略具有重要意义。论文引入水足迹理论,构建区域水足迹结构、效益、生态安全以及可持续性指标体系,对区域水资源的利用现状和可持续性进行评价分析,并以大连市为案例对其水资源利用情况进行评价,结果表明该评价方法简便直观、合理可行。     

能源安全综合评价方法探讨

能源安全是指一个国家或地区可以获取稳定、足量、经济、清洁的能源供给,以满足需求,保障经济社会稳健运行和持续、协调发展的能力和状态。它可用加权综合模型计算得来的"能源安全度"指数进行描述,取值范围最高为1,最低为0,分值越高越安全。研究表明,现实情景下,我国能源安全度平均为0.712 5,处于"基本安全"状态。未来发展规划得当,措施得力,到2020年、2030年能源安全度可提高到0.841 1、0.847 7,进入"安全"区间。若遇针对我国的能源封锁,则能源安全度可能会降至0.552 0的"不安全"区间。解决我国能源安全问题的关键,主要是增加战略储备、实行供应多元化、加强地质勘查、发展替代能源、提高能源效益,而且能源外交也要摆在显著位置。     

中国各区域秸秆资源可能源化利用的潜力分析

在我国能源需求迅速增长并日益依赖国际市场的背景下,能源化利用秸秆资源是我国缓解能源短缺的重要选择之一。论文在综合相关研究成果的基础上,对我国不同区域农作物秸秆可能源化利用的潜力及资源密度进行了分析。研究表明,2009年中国农作物秸秆理论资源量为7.48×10⁸ t,可获得资源量为6.34×10⁸ t,可能源化利用量为1.52×10⁸ t。中国可能源化利用秸秆资源区域分布极不均匀。长江中下游、东北、华北等区域可能源化利用秸秆潜力较大,分别为0.42×10⁸、 0.37×10⁸和0.35×10⁸ t,青藏高原、黄土高原和西南可能源化利用秸秆资源潜力较低。根据各区域可能源化利用秸秆资源密度,论文对不同省份建造较大规模秸秆发电企业或燃料乙醇企业的适宜性进行了分析。     

白洋淀流域水资源管理中的公众参与分析及评价

有效的公众参与是提高流域水资源管理效率和流域综合管理成功的关键因素. 选取白洋淀流域的典型城市模块(保定市)、乡村模块(涞水县)及水敏感区(安新县)进行研究,综合采用问卷调查、利益群体访谈和专家咨询等方法,对政府管理人员、流域居民的环境意识及水资源管理参与现状进行了分析评价,比较与评估了政府及相关利益群体的环境知识、环境满意度、信息流通渠道、参与意愿、实际参与度、政府行为及其公众认知度和接受度. 结果表明:公众参与水资源管理的现状是水敏感区的参与效果好于城镇模块,且城镇模块好于乡村模块;公众获取环境知识与环境信息的途径主要以亲身感受与媒体宣传的被动接受形式为主;参与途径不畅通,实际参与度低于有参与意愿的比例,参与意愿不确定性高;公众对于政府行为的认知度为41.3%,接受度仅为19%;管理者对于公众参与在水资源管理中作用的认识仍有待提高,参与活动以宣传教育为主,缺乏整体考虑及上下游沟通与设计,缺乏全过程参与,居民尚未形成共同认可的流域价值观. 建议加强全过程参与、环保民间团体的作用以及学校环境教育.      

Emergy analysis applied to the estimation of the recovery of costs for water services under the European Water Framework Directive

In this paper, the European Union's Water Framework Directive 2000/60/EC (WFD) that is intended to foster protection of water resources is examined, focusing on the improvement of ecological and chemical quality of surface and groundwater. The WFD includes the concept of full cost recovery (FCR) in accordance with the Polluter-Pays Principle, as one of the tools of an adequate and sustainable water resource management system. The WFD defines three different costs associated with water: resource costs (RC), financial costs (FC), and environmental costs (ECs).The FCR of water is examined from a biophysical perspective using emergy evaluation to: (1) establish resource values of water from different sources, (2) establish the full economic costs associated with supplying water, and (3) the societal costs of water that is used incorrectly; from which the resource costs, financial costs, and environmental costs, respectively, can be computed. Financial costs are the costs associated with providing water including energy, materials, labor and infrastructure. The emergy based monetary values vary between 0.15 and 1.73 €/m³ depending on technology. The emergy based, global average resource value (from which resource costs can be computed) is derived from two aspects of water: its chemical potential and its geopotential. The chemical potential monetary value of different sources such as rain, groundwater, and surface water derived from global averages of emergy inputs varies from 0.03 to 0.18 €/m³, depending on source, and the geopotential values vary from 0.03 to 2.40 €/m³, depending on location in the watershed. The environmental costs of water were averaged for the county of Spain and were 1.42 €/m³.Time of year and spatial location within the watershed ultimately influence the resource costs (computed from emergy value of chemical potential and geopotential energy) of water. To demonstrate this spatial and temporal variability, a case study is presented using the Foix watershed in northeastern Spain. Throughout the year, the resource value of water varies from 0.21 to 3.17 €/m³, depending on location within the watershed. It is concluded that FCR would benefit from the evaluation of resource costs using spatially and temporally explicit emergy accounting.

Occupational Health and Social Resources

There is a relationship between the changes in work-related diseases and the following factors: the transformation of the organization of work, organizational development, as well as human and social changes in the work environment. These factors also influence the maintenance of industrial health and safety standards at work. Safety technology will continue to be important, but will be reduced in significance compared to the so-called soft factors, that is, all dimensions and parameters affecting people’s health and social environment at the work place.

It seems that in the future the relationship between the social resource development and work protection will become more relevant. Social resource development influences the quality of work performance and motivation, the quality of work and work protection, the likelihood of accidents and breakdowns, and the level of self-control and capacity of change.

The consequences of work protection research will be discussed in this article with a focus on the contribution of social sciences.     

海上突发灾难事件应急物资调度优化方法研究

为满足海上突发灾难事件救援对应急物资的需求,最大限度降低其带来的损失,根据海上突发灾难事件的特点,提出救助目标在受复杂气象、海况等因素影响发生漂移/扩散时的海上突发灾难事件应急物资调度方法。综合考虑海洋环境影响,引入救助资源包的概念。构建考虑时间、运力、物资需求等约束条件,以最大限度地满足物资供应可靠性为目标的海上突发灾难事件多级应急物资调度优化模型。通过算例对模型的应用进行验证。研究结果表明,事件形态的演变会影响应急物资集结点的选择,需要在预测事件形态时空变化的基础上合理确定海上应急物资调度方案。
