Past and future sustainability of water policies in Europe

The article contributes to a discussion on two global issues on water: water resources management, and water supply and sanitation. Focusing on Europe, it traces the legal roots of current systems in history: as a resource, water is considered as a common property, rather than a market good; while as a public service it is usually a commodity. Public water supply and sanitation technologies and engineering have developed under three main paradigms: quantitative and civil engineering; qualitative and chemical/sanitary engineering (both on the supply side); and the most recent one, environmental engineering and integrated management (on the demand side). The cost of public drinking water is due to rise sharply in view of the two‐fold financial challenge of replacing an ageing infrastructure and keeping up with ever‐rising environmental and sanitary quality standards. Who will pay? Government subsidies, or water users? The author suggests that apparent successes with privatisation may have relied heavily on hidden government subsidies and/or the healthy state of previously installed water infrastructure: past government subsidies are still felt for as long as the lifetime of the infrastructure. The article stresses the importance of public participation and decentralized local management of water and sanitation services. Informing and involving users in water management decisions is seen as an integral part of the ‘ethics’ side of the crucial three E's (economics, environment, ethics). The article strongly argues for municipal provision of water services, and hopes that lessons learnt and solutions found in the European experience may serve water services management efforts in other regions of the world.

The community vs. the market and the state: Forest use inUttarakhand in the Indian Himalayas

Most writers on resource management presume that local populations, if they act in their self-interest, seldom conserve or protect natural resources without external intervention or privatization. Using the example of forest management by villagers in the Indian Himalayas, this paper argues that rural populations can often use resources sustainably and successfully, even under assumptions of self-interested rationality. Under a set of specified social and environmental conditions, conditions that prevail in large areas of the Himalayas and may also exist in other mountain regions, community institutions are more efficient in managing resources than either private individuals or the central government. In advancing this argument, the paper undermines the often dogmatic belief in the universal superiority of private forms of ownership and management.     

二氧化硫排放总量控制若干问题的思考

根据国家《“十一五”规划纲要》对削减二氧化硫排放总量的要求，在对电力行业脱硫现状及前景的具体阐述中指出实现这个目标的可能性，并从多方面对二氧化硫总量控制的关键问题进行了详尽的论述与分析。     

基于BDD考虑共因失效的接触网系统可靠性分析

为分析共因失效对高速铁路接触网系统的影响，将二元决策图(Binary Decision Diagram，BDD)与共因失效理论引入到接触网系统可靠性分析中。利用逻辑相邻优先组合法(Logic Neighbor Priority Connect，LNPC)将高速铁路接触网系统的故障树模型转化为BDD模型并求取其可靠度表达式，利用隐式方法对考虑了共因失效的接触网系统可靠度进行计算，利用MATLAB绘制考虑共因失效和不考虑共因失效情况下接触网系统可靠度变化曲线。研究结果表明:提出的分析方法适用于接触网系统的可靠性分析，为接触网系统的可靠性分析提供了一定的理论依据。     

论环境自卫权

环境自卫权是环境权的组成部分,环境自卫权及随着环境权的确立而提出来的,环境权作为环境法的核心问题,近年来在国内外的理论界和立法上都有不同程度的反映,使得环境自卫权的实现也就不可避免的带有复杂性,除了必须具备的条件外,环境自卫权的实现还应当注意实施的手段及其相应性的标准,本文就环境自卫权的生成原因、界定、构成及其实现作了初步研究。     

基于改进RPS的共因失效模型及在安全仪表系统中的应用研究

基于安全仪表系统共因失效机理的定性分析,在单一冲击下的RPS模型基础上,以泊松分布作为冲击的先验分布,建立了多冲击下考虑共因失效的安全仪表系统可靠性模型;采用基于专家经验和估计的方法,对模型参数进行估计;并通过定量分析确定出影响系统共因失效的最大冲击因子,为降低系统共因失效对可靠性的影响提供辅助决策支持。将改进的多冲击RPS模型的可靠性分析结果与β模型和PDS模型进行比较,验证了该模型的工程准确性。     

基于耦合协同理论的泥石流危险性评价研究

泥石流地质灾害是降雨、松散物源和自然地理条件共同作用的结果,在泥石流暴发形成过程中,降雨条件、物源条件和自然地理条件三者之间存在着复杂的耦合关系,各要素之间相互作用、协同演化。因此,根据系统耦合协同理论和熵值赋权理论,本文建立泥石流暴发系统的耦合协调评价模型,并对重庆市北碚区典型泥石流单沟进行了耦合协调程度和危险性评价,评价结果与泥石流暴发的实际情况相吻合,能够为泥石流灾害的预防提供理论支撑。     

中美地热能资源管理比较探析

地热资源作为一种清洁能源在欧美国家已经普遍获得立法肯定,并建立起了较为成熟的法律规则。美国在地热资源的界定、地热财税制度、国有资源的保护等方面进行的立法探索,为中国当前的地热资源开发提供了良好的制度借鉴。在欧美国家的实践基础上,中国资源立法可以籍此完善国有资源的产权结构,构建起科学的地热资源用益机制。
