张北6.2级地震邯郸地区前兆异常特征研究

1998年1月10日张北发生MS6.2级地震。在震前一、二年,远在400km外的邯郸地区的多种前兆手段准同步地出现了中期异常变化,这些异常的变化幅度显著,在时间上与张北地震有较好的对应关系,信度较高。分析邯郸地区的前兆异常与张北地震的关系,有利于该区强震监测预报水平的提高,也可为地震前兆特征和机理的深入研究提供实际依据。     

鲁西平原微咸水资源的开发意义

鲁西平原处于黄泛平原的尾闾地段,常受旱涝盐咸多种危害。本文分析了浅层微咸水的形成、水质及动态特征,对水质、水量进行了评价,探讨了开发利用微咸水的可能性及灌溉效益。农业上开采浅层微咸水,无疑对扩大地下水资源及促进鲁西平原水、土环境的良性循环有重大意义。     

On the influence of sand-wind on atmospheric environment

The authors seek, through tests on simulated sand samples in a wind tunnel and analysis of minerals combination and trace elements, to discover the environmental implications of flying-up, falling-down and concentration variation as a function of natural wind speed and direction, distance of movement, range and extent of influence on the atmospheric environment, of micro-granular components on the ground surface in the Keerqin desert area in northwest Liaoning Province of China.     

天津污灌区苯并(a)芘的分布和迁移通量模型

建立了估算苯并 (a)芘在天津污灌区气、水、土壤及沉积物相间的迁移通量和浓度分布的逸度模型框架 ,利用通量资料作为模型输入 ,利用实测浓度数据验证了模型的可靠性 .结果表明 ,模型对大气、地表水、土壤和沉积物中浓度的估算大体吻合 ,沉积物和土壤是苯并 (a)芘的主要环境归宿 ,而大气中的平衡浓度相对较低 ,水体及土壤中的苯并 (a)芘可能通过作物和鱼体富集而进入生态系统 .     

风向变化对城市大气污染的影响及试验分析

针对城市大气污染的复杂多变状况，在理论分析的基础上，通过风洞实验对城市大气污染扩散模型进行了模拟试验研究，建立了适合一定条件下城市大气污染物扩散的数学和物理模型，并对城市大气污染状况的影响因素进行了分析，在得到特定条件下城市大气污染扩散普遍规律的同时，重点讨论了风向变化对城市大气污染的影响，该方法同时还可以应用于城市大气污染物扩散浓度的估算。     

污染环境的刑事责任问题探讨

根据一些发达国家的法律实践和我国环境保护工作的实际需要,探讨了对环境造成严重恶果的行为,应设立“污染环境罪”来调整人们行为的最后法律手段的必要性,并就污染环境罪的基本特征及与其它法律责任的区别作了分析和阐述,提出在我国刑法中应专条补充设立“污染环境罪”规定的建议。     

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.
