浅析国际环境公约对石油工业的影响

随着人类环境意识、资源意识的不断深化,越来越多的国家签署了国际环境公约。中国石油企业若要进一步参与国际化竞争,在环境保护方面就势必面临更大的挑战与压力。对气候变化框架公约、巴塞尔公约、湿地公约、海洋环境保护公约以及酸雨问题等与石油工业相关的国际环境公约进行了分析及探讨,以期为石油工业适应环境保护工作发展的需要及提高国际竞争力制定相应对策提供参考。     

Evolution of the Stewardship Idea in American Country Life

Theological and secular concepts ofstewardship evolved markedly in the 20thcentury. During this period of evolution, theAmerican Country Life Association through itschurch, academic, farm organization, andgovernmental affiliations, served as a bridgingand bonding agent in developing the stewardshipidea. As in any evolutionary process, thestewardship concept was subjected to a broadarray of influences and characterized bynotable highlights such as the Lynn Smithcritique of the Judaeo-Christian ethic, theman-in-nature statement of Douglas John Hall,and the environmental concerns of ecologistsand philosophers of the post-Rachel Carson era.Some gains have been made in understanding theplace of humans in nature, but the stewardshipidea continues as work in process.     

Significant developments in sustainable development law and governance: A proposal

This article develops a practical proposal for progress on sustainable development law. It examines the prospects for an international sustainable development law to provide a framework for more effective, coherent governance. Sustainable development law is briefly defined and an analytical framework is provided. Different degrees of integration between economic, social and environmental law are described. Certain principles of international law related to sustainable development are also highlighted. It is argued that these principles may serve to guide law‐makers and jurists where social, economic and environmental law and policy conflict or overlap. Continuing, underlying questions of sustainable development governance are addressed and its global frameworks analysed. The article also focuses on the 2002 World Summit on Sustainable Development, held in Johannesburg in August‐September 2002, and its specific mandate for the United Nations Commission on Sustainable Development (UNCSD) to take related legal developments into account. The article advances a proposal: that governments, economic, social and environmental intergovernmental organizations and other actors establish a ‘network of inquiry’ with members from relevant groups, including legal and academic organizations, and other expert groups, in order to follow, research, analyse and debate legal developments in a balanced way.     

TEMPORAL CHANGES IN THE YADKIN RIVER FLOW VERSUS SUSPENDED SEDIMENT CONCENTRATION RELATIONSHIP1

ABSTRACT: Dynamic linear models (DLM) and seasonal trend decomposition (STL) using local regression, or LOESS, were used to analyze the 50‐year time series of suspended sediment concentrations for the Yadkin River, measured at the U.S. Geological Survey station at Yadkin College, North Carolina. A DLM with constant trend, seasonality, and a log₁₀ streamflow regressor provided the best model to predict monthly mean log₁₀ suspended sediment concentrations, based on the forecast log likelihood. Using DLM, there was evidence (odds approximately 69:1) that the log₁₀ streamflow versus log₁₀ suspended sediment concentration relationship has changed, with an approximate 20 percent increase in the log₁₀ streamflow coefficient over the period 1981 to 1996. However, sediment concentrations in the Yadkin River have decreased during the decade of the 1990s, which has been accompanied by a concomitant increase in streamflow variability. Although STL has been shown to be a versatile trend analysis technique, DLM is shown to be more suitable for discovery and inference of structural changes (trends) in the model coefficient describing the relationship between flow and sediment concentration.

基于GIS的长江中下游地区洪灾风险分区及评价

国内外近几年的发展表明,在所有可能避免和减轻自然灾害的措施中,最简单有效的方法就是通过在科学研究基础上进行风险区划,将自然灾害管理提高到风险管理的水平.在长江流域数字化地图的基础上,选取不同重复期(20,50,100年),及包括1870年历史洪水和1931,1935,1954,1991,1995,1996,1998,1999和2002年共10次洪水,借助Arcview地理信息系统的空间分析和叠加功能,对长江中下游地区的洪水灾害危险性进行了初步评价.首先参考洪水灾害淹没图和相关历史文献记录资料,构建10次洪水受灾县(市)分布图;其次对这10次洪水受灾县(市)分布图进行叠加,得到长江中下游地区洪涝灾害风险性评价图.分析表明:长江中下游地区洪水风险的分布是有规律的,而且具有明显的地理意义.有4个明显的高危风险区,分别是洞庭湖、鄱阳湖两湖平原的湖滨地区和公安以下的长江中游河段的沿江一带,尤其是荆江河段以及两江相夹地势低洼的江汉平原;沿高危风险区外侧为高风险地区,重点在汉江下游、资、沅、澧水、清江流域、皖沿江地区以及太湖流域的部分地区;沿长江于高危风险和高风险地区两侧分别为风险较小地区;其他地区对于洪水灾害而言则为安全地区.评价结果与长江中下游的实际情况基本吻合.     

新疆融雪措施对环境的影响及其防治对策

随着国民经济的飞速发展，促进和带动了城市化发展，在我国北方寒冷地区城市中，积雪对城市发展和交通安全运营的制约因素越来越受到各界人士的关注。有关部门引进并使用融雪剂去除冰雪，融雪剂在提高清除积雪效率的同时，也给城市的基础设施和生态环境带来潜在危害。为了正确合理的使用融雪剂，了解融雪剂的特性和它的融雪机理是十分必要的，在此基础上提出减轻危害的对策，为今后正确使用融雪剂提供参考依据。
