俄罗斯的天然气输送与环境保护

俄罗斯年产天然气５０００×１０８ｍ３，年输天然气２４００×１０８ｍ３，输气干线多采用多管线并列埋设方式。大量的长输管道、加压站和地下储气库的设计和施工都必须解决相应的环境保护问题。在河床处多采用埋管的办法；在沙漠地带要尽可能避开流沙地区；在永冻地区应注意输气管道的加热效应；过铁路的交叉口应设计自动监测系统；在确定管道线路时，必须注意生态保护；用植树绿化等方法尽量减轻加压站内燃气轮机发出的噪音危害；地下储气库的环境保护重点是回注水的处理。最后阐述了管道等输气工程的工作程序及所使用的法规和标准等。     

石油测井用中子源辐射屏蔽研究

放射源测井技术是当今石油勘探和开发中必不可少的手段，开展对测井人员的屏蔽防护研究十分必要。将聚乙（丙）烯与碳化硼和氧化铝等以不同比例混合后制成的板材和织物具有良好的热中子、中能中子和快中子屏蔽效果，加工成屏蔽装置后，可使镅－铍源中子的屏蔽率达到６２．０６％，γ射线屏蔽率达到３２．４３％，结合中子辐射防护服和防护围裙等的使用，可较好地解决测井人员的辐射防护问题。     

合理规划实现污染集中控制

污染集中控制是在一个特定范围内，为保护环境建立的集中治理设施和采取相应的管理措施，是强化环境管理的一种重要手段［１］。当前，各工业化国家的有害废物处理和处理设施正向大型化、集中化方向发展，污染集中控制是环境治理的发展趋势。污染集中控制在环境管理上具有战略意义，为污染防治战略和投资方向带来重大转变。实行污染集中控制，必须以规划为先导。本文从环境规划的角度出发，就大庆油田宏伟化工区在“九五”规划中有关的环境规划进行分析探讨，介绍了目前化工区污染物的排放情况，阐述了“污染集中控制”制度在化工区规划中的应用及将取得的经济、环境效益，同时介绍了该制度在大庆油田其他方面的应用。     

天然放射性物质及环境问题

天然放射性物质（ｎａｔｕｒａｌｌｙｏｃｃｕｒｒｉｎｇｒａｄｉｏａｃｔｉｖｅｍａｔｅｒｉａｌｓ，简称ＮＯＲＭ）广泛存在于地层中，当石油或天然气从地下开采出来时，痕量的天然放射性核素如镭、氧等也随之采出，并分别集中于管道及设备的垢层或天然气加工装置的内壁薄膜上。文章在对外文资料调研的基础上，将ＮＯＲＭ的有关知识、存在场所、对人体潜在的危害途径及有关辐射防护方法进行了介绍。     

THE VALUE OF STREAMFLOW FORECASTING IN RESERVOIR OPERATION1

ABSTRACT: The value of streamflow forecasts in reservoir operation depends on a number of factors and may vary considerably. Assessment of forecast benefits is presented here for three specific systems. Statistical streamflow models of increasing forecasting ability are coupled with a recently developed stochastic control method in extensive simulation experiments. The performance of the system is statisticafly evaluated with regard to energy generation and flood and drought prevention. The results indicate that forecast benefits are system specific and may range from quite substantial to fairly minimal.     

Culture and the environment in Britain

The British pride themselves on their long tradition of landscape management rooted in the aristocratic and landowning classes of the 18th and 19th centuries. The British also emphasize that the rise of modern pollution control began in the Victorian industrial era with the emergence of the national Inspectorates and the local Commissioners of Sewers. All these traditions are rooted in British social history, which was heavily influenced by class, power, and the changing shape of industrial and agricultural development. In modern Britain, affected by industrial recession, where concern over jobs and growth appears to dominate public and political attention, as well as public spending cuts that sap the morale and effectiveness of the major regulatory agencies, attitudes toward, and the execution of, environmental protection are undergoing a subtle but profound revolution. It is slowly but agonizingly being recognized that economic growth and social well-being cannot be disconnected from environmental processes and the limits these impose on management and technological intervention. A 21st century Britain will have to integrate conservation with development in order to survive.
