河流健康的概念既强调了保护河流生态系统的重要性,也承认人们适度开发水资源的合理性。把维护河流健康作为流域管理的战略目标是管理理念的重大突破。维护河流健康不仅需要工程技术的支持,也需要进行立法和机制体制改革,实行流域一体化管理。 相似文献

中国主要河湖水生态综合评价 总被引:9,自引:1,他引:8
河湖水生态综合评价是水资源保护规划工作的重要内容之一。本文从水文水资源、水环境、河湖生境形态、生物及栖息地状况等方面,构建了包含生态基流满足程度、水功能区水质达标率、湖库富营养化指数、纵向连通性、重要湿地保留率及鱼类生境等6个指标构成的河湖水生态综合评价体系。在此基础上,对全国673条河流、97座水库和100个湖泊湿地共计1006个规划河段和湖库的水生态状况进行了评价和分类,分析了我国各大流域河湖面临的水生态问题。研究成果对我国主要河湖水生态保护和修复工作的实践具有重要的指导意义。 相似文献

Lake management is typically approached from a biophysical perspective. Lake managers ask how lakes can be managed to sustain their ecological functions. The social value of lakes is usually given less attention. The present paper begins the analysis at the other end of the lake and society connection by posing the question: what social needs must be met to sustain society? The primary social needs of sustainable societies are outlined and then the contribution of lakes to each need is discussed. Lakes can only provide optimal social benefits if management decisions recognize the full set of potential contributions lakes can make to society and those management decisions are integrated to provided balanced attention to all values that lakes provide. The present paper expands the domain of values beyond the traditional environmental and recreational contributions of lake management to also include aesthetics, education, economic opportunity, emotional security, cultural opportunity, individual freedom and spirituality. Citizen involvement is essential in broadening the conceptualization of the lake values and in implementing integrated management plans. 相似文献

The water level in Lake Vegoritida, Greece, has undergone great changes over the past decades attributable to severe water abstraction directly from the lake and its catchment, which affected not only the conditions of the natural environment, but also social and economic conditions. The water level of the lake is currently rising, with discussion of an agreeable decision about the desired maximum lake water level becoming a source of conflict among the lake stakeholders. The present study provides a framework for a participatory management plan, with the perspective of engaging all levels of lake stakeholders in the process of deciding and establishing the maximum lake water level. Kolb's learning cycle is used as a methodological vehicle in the proposed process of participatory decision‐making. Its contribution to decision‐making includes (a) identification of lake stakeholders and the issues arising from a potential establishment of a maximum lake water level; and (b) three suggested water level scenarios to facilitate a future constructive discussion directed to establishing a maximum water level in Lake Vegoritida. 相似文献

在界定幸福河湖概念及内涵的基础上,构建了包括安全河湖、健康河湖、富民河湖、文化河湖4个方面共17项指标的幸福河湖综合评价指标体系。运用最优最劣法(BWM法)确定指标主观权重,运用CRITIC法确定指标客观权重,并通过最小鉴别信息原理得到组合权重。基于TOPSIS法建立幸福河湖综合评价模型,并通过评价浙江省某市2015—2019年幸福河湖建设水平对模型进行了验证。结果表明:BWM-CRITIC-TOPSIS模型可有效评价幸福河湖建设水平,评价结果与实际情况相符;湿地占地比例、水资源开发利用率等指标限制了该市幸福河湖等级的提升。提出了促进人水和谐、合理利用水资源、提高水资源利用效率等建议。 相似文献

Flood defences are in practice often multi-used, multi-managed and multi-financed. Flood defence asset management contains technical, organizational and spatial complex issues involving multiple organizations. In the literature, little attention has been given to the conditions for successful cooperation between organizations in flood defence asset management. This paper elaborates on this aspect of mature asset management from a practical point of view. Although the importance of a fit-for-purpose cooperation seems trivial, practice shows that the shape of cooperation is often the coincidental result of implicit or ad-hoc choices and is not deliberately designed. This paper reports on empirical data gathered in a case consisting of five different situations related to collaboration in flood defence management. The management context consists of three main tasks: performance assessment, reinforcement and daily management, and three decision levels: strategic, tactical and operational, resulting in nine different management environments and related interfaces. For effectively achieving desired outcomes, the shape of cooperation has to be explicitly chosen dependent on the complexity of content and organizational context, and relevant external circumstances: situational cooperation. 相似文献

A three-step interdisciplinary method to assess approaches to water shortage, water quality and flood risks is presented. This method, based on water system analysis, economics, law and public administration, seeks to create common understanding based on newly developed concepts and definitions. First, generating content knowledge about the water system and about values, principles and policy discourses. Second, providing an organizational process with sufficient stakeholder involvement, insight into the trade-off between social objectives, and attribution of responsibilities in addition to regulations and agreements. Finally, implementing the agreed service level through adequate infrastructure, enforcement and conflict resolution. 相似文献

Salinization is a global threat to freshwater habitats that has been intensified by climate change. Monitoring, assessment and management of salinity is therefore essential. The first step is to set criteria that are sufficiently stringent to protect ecosystem health. However, many countries have not yet defined criteria, and there are substantial differences between criteria. This has been noted in the EU, where salinity is a required “supporting element” for ecological status in inland waters but also for implementation of UN Sustainable Development Goal (SDG) indicator 6.3.2. for “good ambient water quality” where different approaches and widely different threshold values were reported for salinity criteria. Much of this information has not been published and is difficult to access, hindering further efforts to address the problem. We first discuss the implications of salinization for freshwater ecological health. We go on to discuss the principles and guidelines on how salinity criteria to protect ecology should be established. Next, we review salinity criteria submitted as part of implementation of SDG indicator 6.3.2 and the EU Water Framework Directive. Finally, we discuss setting salinity thresholds in an already-warming world and the challenges facing anyone trying to develop salinity criteria to protect freshwater ecosystems. 相似文献
