基于整体开发管理的国际河流决策支持系统

基于国际河流开发管理的现状，分析国际河流整体开发管理理论的演进。得出整体开发管理决策实施的原则及思路：流域开发管理要以流域边界为界，将整个水系自然联系的区域作为不可分割的整体，进行统一权衡，突出共同利益，流域内开发与流域外开发相结合。以建立多层次的国际合作机构。对国际河流决策支持系统进行设计，即以国际河流流域为体系，各国国内流域测点为单元。国际流域综合协调委员会为决策支持中心、各国流域机构委员会为决策支持分中心。并研究系统的公用信息平台建设，信息开发、管理与维护。河流水资源、水环境实时监控等技术支持系统。实证分析澜沧江-湄公河流域决策支持系统的建设。并指出国际河流水资源的开发与管理，水权等问题有待进一步深入研究。     

INTERNATIONAL MANAGEMENT OF THE GREAT LAKES-ST. LAWRENCE BASIN1

Neither Canada nor the United States attach much importance to the International Joint Commission (IJC) judging by the size of staffs and annual budgets. The Commission has been restricted to a relatively minor number of functions in the Great Lakes-St. Lawrence. It has investigated: the degree and causes of water and air quality deterioration; the effects of hydroelectric and navigation projects on water levels; the impacts of water-level fluctuations; and the feasibility of a deep waterway from the St. Lawrence to the Hudson River. Projects approved by the Commission have produced less than might be expected through no fault of the Commission. The Great Lakes Fishery Commission has promoted little international management. Budgetary limitations restrict its lamprey control program; institutional limitations restrict its ability to deal effectively with fishery problems. Commission responsibilities are limited to coordination and advisory functions. Since Canada and the United States have not chosen to refer most aspects of river basin management to international bodies, an institutional void exists in the Great Lakes Basin to consider these questions on a continuous basis. There is a need for expanded international cooperation.     

全球可持续发展与国际合作

本文认为环境生态是全球可持续发展的重要组成部分,必须在全球范围内,通过有效的国际合作和国际协调来加以解决。作者认为:国际合作应在国际性河流流域管理方面发挥重要作用。对全球温室效应问题,国际组织应重视科学研究,协调各国政府在能源税收、补贴和开发再生能源方面取得进展。此外,在保护地球生物多样性方面,国际组织可调试债务与自然环境互换机制。     

中国生态环境保护管理体制改革思路与方向:国际社会的观察和建议

本文对2000年以来国际组织和研究机构针对中国生态环境保护管理体制改革的研究进行了梳理和分析,总结了这些研究中提出的现行生态环境保护管理体制存在的主要问题,以及对于中国生态环境保护管理体制改革思路和方向的政策建议。本文对已实现的建议进行了分析,提出了未来生态环境保护管理体制改革亟待解决的问题。     

新型污染物风险防范国际实践及其对中国的启示

随着重化工业的快速发展和各类化学品的大量使用，一些新型污染物对中国居民和生态环境的危害正逐步显现并日趋严重。如何进一步完善中国新型污染物的风险防范体系，是中国生态环境治理面临的重要问题。发达国家新型污染物的风险防范工作启动较早，对中国完善新型污染物风险防范体系具有重要的借鉴意义。本文从制度建设、体制机制、评估监测、科学研究等方面比较国内外新型污染物风险防范实践的异同，立足我国国情，发现国内实践还需加强之处。在此基础上，提出国际新型污染物风险防范实践对中国的启示。

Modeling Flow,Nutrient, and Sediment Delivery from a Large International Watershed Using a Field‐Scale SWAT Model

A large international watershed, the St. Clair‐Detroit River System, containing both extensive urban and agricultural areas, was modeled using the Soil and Water Assessment Tool (SWAT) model. The watershed, located in southeastern Michigan, United States, and southwestern Ontario, Canada, encompasses the St. Clair, Clinton, Detroit (DT), Sydenham (SY), Upper, and Lower Thames subwatersheds. The SWAT input data and model resolution (i.e., hydrologic response units, HRUs), were established to mimic farm boundaries, the first time this has been done for a watershed of this size. The model was calibrated (2007–2015) and validated (2001–2006) with a mix of manual and automatic methods at six locations for flow and water quality at various time scales. The model was evaluated using Nash–Sutcliffe efficiency and percent bias and was used to explore major water quality issues. We showed the importance of allowing key parameters to vary among subwatersheds to improve goodness of fit, and the resulting parameters were consistent with subwatershed characteristics. Agricultural sources in the Thames and SY subwatersheds and point sources from DT subwatershed were major contributors of phosphorus. Spatial distribution of phosphorus yields at HRU and subbasin levels identified locations for potential management targeting for both point and nonpoint sources and revealed that in some subwatersheds nonpoint sources are dominated by urban sources.     

Understanding the synchronisms and anachronisms of the Columbia River Treaty in relation to the principles of international water law

Based on the theory of the politics of international law and the hermeneutic theory for international relations, this paper aims to demonstrate how the history and contextual changes within the Columbia River Basin have affected the underlying principles of the Columbia River Treaty with those of international water law.     

Two Major Relative Comparative Advantages of China in International Trade

Sustainable development requires enriching and developing the traditional international trade theory, especially integrating the environmental elements into the current analysis framework of relative comparative advantages. These relationships among labor, capital, and environmental resources are analyzed in this study, using the relative comparative advantages method. As indicated in the analysis, the ever-increasing international trading volume in China relies not only on the relative comparative advantage of labor but also on the environmental one; these are the two major advantages in China. However, the two advantages will experience serious challenge in the future along with a rising cost on labor and environmental pollution.     

国际铁矿石定价机制改变与我国铁矿石进口量变化的实证分析

随着我国对外贸易和国内钢铁企业的发展,我国铁矿石进口量大幅上升,已成为全球最大的铁矿石消费国。与此同时,国际铁矿石巨头摒弃长期协议定价机制,单方面推行季度、 指数等定价模式。为了认识国际铁矿石定价机制改变对我国铁矿石进口的影响,论文基于铁矿石进口量、 铁矿石价格、 国内原矿产量等统计指标的月度数据,通过定性分析与Granger因果检验,综合判断国际铁矿石定价机制改变与铁矿石进口量变化之间的关系。结果表明:近两年我国铁矿石进口量的短期波动频繁;国际铁矿石定价机制改变引起的铁矿石价格震荡是导致我国铁矿石进口量波动的主要动因;结合国内外形势判断,未来一段时期内我国铁矿石进口量的短期波动还会持续。
