水与能源安全是全球可持续发展最为核心的问题,其在国际河流区尤为复杂和敏感。中国作为亚洲乃至全球最为重要的上游国,国际河流水资源变化、水电开发影响及跨境水安全维护等,虽受关注,但研究基础较为薄弱。判识出1937-2010年全球国际河流水电合作开发的32个案例,综合分析其开发方式,揭示其投资—效益分配模式与特征。结果表明:1水电合作开发以河段和双边合作开发为主,缺乏流域层面的合作,形成了投资—效益等比分配、平均分配和差异分配三种模式。2跨境型河流水电合作的投资—效益分配以等比分配为主,上游国通过向下游国提供发电用水分享其发电效益,下游国则通过补偿上游国的方式推动合作;界河(含界河段)的水电合作开发以平均分配为主。3不同发展时期的分配模式差异较明显:1950年代前以平均分配和等比分配为主;1950-1980年代以平均分配为主;1990年代以后,因案例太少,主要分配模式难以确定。4经济发展水平相当的合作国家间主要采用平均分配模式;经济发展水平存在差异的国家间则兼顾采用等比分配和差异分配模式,并实施了更多的补偿措施。  相似文献

澜沧江水资源系统变化与大湄公河次区域合作的关联分析   总被引:3,自引:0,他引:3  
针对澜沧江-湄公河水资源系统变化的跨境影响这一受到国际社会,特别是下游国关注的问题,结合流域各国水需求及区域性协定之规定,对比分析澜沧江大坝建设后对径流的影响,发现:(1)年出境水量呈小幅增长趋势,总体上有利于下游水资源利用;(2)个别年份枯季出境水量明显减少的主要原因是降水少和个别电站运行失误所致,电站本质上不会对下游用水和生态产生实质性危害;(3)出境水量变化主要对下游中上段产生明显影响,越往下游影响力越小;(4)出境水质稳定。建议:尽早制定流域综合规划和国际水分配方案;合理调整水库运行方案,避免出境水量或水位的大幅变化,减少跨境负面影响,维护区域合作。  相似文献

国际河流水资源的“权利”问题研究对于维护国家安全和地区安全、人民生计乃至全球水资源的可持续发展迫在眉睫。现代国际水权是扣除了流域生态需水和流域人口最低需水的水量,每个国家的国际水权水量份额就是水量总量乘以各自流域国家产水贡献率。水资源合作是澜湄合作的旗舰领域。如何推动澜湄水资源合作走深、走实、走远,妥善应对各种风险挑战,为区域可持续发展与共同繁荣提供有力的水安全保障,是澜湄六国面临的共同课题。倡导国际水权确权可以突出澜湄水资源合作的专业色彩、体现水合作对当地水人权的关怀、并能有效反驳“中国水威胁”论调。  相似文献

Transboundary rivers have important geopolitical and geo-economic connotations, but riparian states of transboundary rivers are often driven by their own rapid population growth and economic development to be-come involved in regional conflicts about the development and use of water resources. Therefore, finding a balance between the need for fair and reasonable development of water resources and the effective protection of environment from an ecological perspective has become a major problem faced by the international community. This paper begins with consideration of international water laws related to transboundary rivers and then reviews advances in the research on benefit-sharing, ecological compensation mechanisms, and adaptive management systems. We believe that existing international water laws form a complete legal system and that more attention needs to be paid to transboundary cooperation and sustainable water resource use. With respect to how transboundary water conflicts are resolved, there is a trend to move away from single water resource allocation (a zero-sum game) to benefit-sharing in order to achieve a win-win situation for riparian states, but there are still some difficulties in transboundary ecological compensation. In China, the central government has paid attention to horizontal ecological compensation between upstream and downstream, offering guidance to promote establishment of inter-province ecological compensation. Based on existing practice, horizontal ecological compensations are still in their infancy, small in scale, supported by a weak legal system, lacking market mechanisms to encourage their use and relying on fiscal transfers as the method of payment. In the future, China will need to intensify its research on legal system development, international cooperation, and benefit-sharing as these impact transboundary water resources. Because government can be seen as a management department with multiple identities (enabler, regulator and buyer), to improve adaptive transboundary ecological compensation mechanisms, government must develop as soon as possible data sharing platforms, standards of water consumption behaviors and intergovernmental policies (or ordinances).  相似文献

With the regional population growth, socioeconomic development, more and more attention has been paid to issues on the shared water allocation and the transboundary eco-security conservation during the development of water resources in the international rivers. In this paper, the existing major problems on transboundary waters in different sub-regions of Asia, such as water shortage, transboundary waters pollution, fragile eco-environment are discussed. Then, the key scientific issues to be concerned in the next study progress on the basis of the analyses of the new research directions and focus fields are raised: (1) unpredicted changes of the hydrologic and water system, and their impacts on the allocation of the sharing waters by global changes; (2) models of the international cooperation on the international rivers on the studies of international and national water laws or regulations, policies, the relative experiences and the case studies; (3) quantificational assessment on environmental flow, available water, and the comprehensive functions and values of the international watercourse system; (4) studies on transboundary aquatic bio-diversity maintenance, transboundary pollution supervision and treatment under the rules and principles accepted by the riparian states; (5) issues on transboundary compensation at the rules of “payments for using”, “payments for harm” and “compensation for benefit”; (6) using advanced 3S techniques to promote the integrated watershed development and management; and so on.  相似文献

基于前期研究中获得的8个河流健康主要评价指标、3个主要跨境水分配指标的结果以及指标之间的相关性,确定了河流健康和跨境水分配的关键指标:多年平均水量、最大取用水量和最小维持水量。跟踪查询《国际淡水条约数据库》内1864-2002年应用3个关键指标的38个国际条约及其所涉及28条国际河流的主要水文信息,通过对条约中水分配指标的标准化计算和分析,得到各指标阈值及其区域性特征:① 最小维持水量指标得到普遍应用,其次是多年平均水量指标,而最大取用水量指标应用率明显低于前两个指标。② 应用多年平均水量指标,在界河上基本确定了平均分配方案,阈值为50%;“内河”属性支流的阈值为100%;跨境河流上产生了较多的差额分配方案和较多的上游国用水多于下游国的方案。③ 最小维持水量指标,其应用有从发达地区向发展中地区扩展、从保证用水向维持生态用水发展的特点;当该指标在跨境和界河的河流尺度上用于保证供水时,该指标阈值平均分别为41.7%和50%,且流域国家实力对其影响极为明显,而在跨境河流河段尺度上阈值平均为36.1%;用于维持河道生态水量时,阈值平均为14.7%,并有逐步增长的趋势。  相似文献

Tensions over freshwater resources may become more frequent as pressures on water resources grow due to increased demand and variability of rainfall. Conflicts may take place between or within countries or between competing sectoral users. This paper focuses on institutional approaches for enhancing cooperation between countries for sustainable development of transboundary freshwater bodies and contributing basins. It is assumed that instead of being zones of conflict, shared water resources can provide a basis for cooperation and benefit–sharing provided that threats to the international waters are recognized and collaborative structures are created. The paper draws upon experiences gained within the international waters focal area of the Global Environment Facility, the main funding mechanism for countries to support the environmental management of transboundary water resources. Lessons for promoting peaceful cooperation for environmental management, benefit–sharing and sustainable use of transboundary freshwater resources are highlighted through examples from Africa, Central Asia and Latin America. Experience shows the importance of processes that bring together all sectors and actors whose actions affect the transboundary waterbody at regional, national and local levels. The development of a science–based diagnostic analysis is essential to identify the threats to the transboundary ecosystem and to break down the issues into manageable parts with the aim of developing a strategic action programme. Ensuring political commitment that can result in institutional, policy and legal reforms in the countries concerned is the key to sustainable development of the transboundary resource.  相似文献

Competitive use of transboundary freshwater resources is becoming one of the key factors influencing regional peace and political relationship among states. In China, 18 major international river basins are concentrated in three regions, of which the total annual outflow at the border is 7320×108 m3, occupying 26.8% of the total annual runoff of China, and the inflow at the border is only 172×108 m3. In this paper, we analyzed the major drivers affecting shared water vulnerability in China, namely: (1) changes in physical conditions affecting the availability of water; (2) competing objectives between economic development and ecological conservation; (3) lack of emergency response mechanisms; (4) unsound administrative institutions; and (5) shortcomings in the development of regional cooperation based on transboundary waters. We concluded by identifying four pathways for reducing vulnerability: (1) encouraging scientific research cooperation; (2) constructing information-sharing channels; (3) establishing early-warning mechanisms; and (4) promoting further coordination and negotiation.  相似文献

China possesses over 110 international rivers and lakes, among which 41 are major ones and 15 are of great importance. With the highest concentration of international rivers, the northeast, northwest and southwest regions of China enjoy abundant transboundary resources and pose complicated ecological security issues. Following the 1950s, relevant studies on international rivers fall into three periods: 1) the planned economy period of the 1950s–1980s when border development and basic research were scant; 2) the reform and opening-up period from 1980 to the end of 20th century. Along with the drive of economic globalization and regional cooperation, development of international rivers was thriving, which filled blanks in the research and narrowed gaps with international standards. Relevant studies also provided national and local governments with important scientific grounds for making decisions; 3) since the start of the 21st century, China has integrated its international river studies across sectors and across international borders. Now both government and scientific institutions pay great attention to transboundary environmental issues.  相似文献
