水资源承载能力评价方法研究及应用 总被引：3，自引：0，他引：3
为全面客观评价水资源承载状况,进而为经济社会发展合理布局提供理论支撑,本文在对水资源承载能力评价研究现状进行综述的基础上,考虑水量、水质、水生态3个要素,讨论分析了水资源承载能力内涵,从水资源承载负荷和承载能力2个方面出发,构建了水资源承载能力评价指标体系,采用实物量指标对水资源承载能力各因素分别评价,采用“短板法”全面考虑各要素评价结果,进而得到水资源承载能力综合评价结果。并以河北省为案例进行水资源承载能力评价,最后结合资源承载状况和超载成因,提出了河北省水资源调控措施建议,以验证评价方法的合理性与可行性。 相似文献

China has made great progress in the study of socio-economic water cycle. She has completed national water resources appraisement and medium to long-term water supply planning. She has been engaging in study on water-deficient regions in North China and Northwest China for about half a century. For solving water shortage problem in northern China, she has put forward the famous South-to-North Water Transferring Projects, which has been set as one of the four biggest national projects in the Tenth Five-Year-Plan period although there are still debates. For promoting water use efficiency, China has been reforming her water management system, including water right system and water price system. There has already been a case of water right purchase. China has also done a lot of research on the interaction between human activity, water and ecosystem. For meeting the need of sustainability and coordinating water resources development and environmental protection, the study of ecological water requirement became very hot in recent years. There are three focuses of socio-economic water cycle study now in China: water transfer projects from the south to the north, water resources management and ecological water requirement. 相似文献

论水权的性质及构成 总被引：1，自引：1，他引：1
水权的客体、性质和权能结构可从其自然属性、经济属性、法律属性三方面进行分析。水权是自然资源产权，水权的客体是水资源而非水产品，即生态用水之外的部分水资源。水权是具有公权色彩的私权，是符合物权属性基本前提下的准物权。我国水资源为国家所有，在水权权系构成中，水资源所有权是第一位的权利。水资源所有权的派生权利如占有权、使用权、部分收益权、部分处分权等可与所有权相分离并进行流转，从而形成水权市场和水权交易制度。在我国，水资源使用权即是取水权，根据取水方式的差异，包括汲水权、引水权、蓄水权等；根据水资源使用方式的差异，则包括灌溉权、经营权、饮用权等。本文认为，水域(水面)使用权、排水权、水资源分配权等不属于水权的范畴。 相似文献

社会经济系统水循环研究进展 总被引：23，自引：1，他引：22
水循环包括自然水循环和社会经济水循环两个方面。社会经济系统水循环指社会经济系统对水资源的开发利用及各种人类活动对水循环的影响。对目前国际国内关于社会经济水循环关注的主要问题 (水资源安全、水资源社会经济研究、人类活动对水循环的影响、水环境、水资源可持续管理和综合管理) 及其进展进行了评述。水资源安全的主要对策已由增加供给转变为水资源需求管理。增加社会参与和明晰水权是水资源管理体制改革的方向。水价在水资源管理中的重要作用得到越来越多的重视。水资源可持续管理和综合管理正逐步落实。水资源需求管理机制、水权水价等水资源管理制度设计、作为可持续水资源管理基础的生态需水问题和环境变化对水资源的影响,将是未来社会经济系统水循环研究的焦点。 相似文献

Water footprint of production can be used to identify pressure on national or regional water resources generated by production activities. Water stress is defined as the ratio of water use (the difference between a regional water footprint of production and a green water footprint) to renewable water resources available in a country or region. Water stress can be used to identify pressure on national or regional water resources generated by production activities. This paper estimates the water footprint of production and the water stress in China during the years 1985-2009. The result shows that China’s water footprint of production increased from 781.58 × 109 m3 in 1985 to 1109.76 × 109 m3 in 2009. Mega-cities and regions with less agriculture production due to local climatic conditions (Tibet and Qinghai) had lower water footprint of production, while the provinces (Henan, Shandong) with higher agriculture production had higher footprint. Provinces with severe water stress increased from 6 in 1985 to 9 in 2009. High to severe water stress exists mainly in mega-cities and agricultural areas located in the downstream areas of the Yellow River and the Yangtze River in North and Central China. The outlook for water resources pressure in China is not optimistic, with areas of stress expanding from northern to southern of China. 相似文献

The Third Plenary Session of the 18th Central Committee of the Communist Party of China has proposed an important national strategic decision:to explore and establish the balance sheet of natural resources,to implement leaders' of-office auditing system about natural resources assets.Water is one of the most essential nature resources of human beings;water resources accounting,as an important water resources management tool,is an essential part of compiling the natural resources balance sheet.In this paper,we provide a summary of the historic evolution of water resources accounting and analyze its application in some typical countries.Although water resources accounting and water resources balance sheet reflect different implications and focus,both require water resources accounts as the basis in system establishment. 相似文献

水资源管理模式评述与展望 总被引：6，自引：5，他引：1
导致我国水资源利用效率低下和水危机产生的根本原因,并不完全在于水资源的短缺及缺少节水技术和污水处理循环利用技术,而在很大程度上归因于缺乏一种能够有效地促进水资源高效配置和节约用水的水资源管理模式。因此,建立一种科学合理和高效的水资源管理模式是我国水资源管理制度改革与创新的关键所在,也是我国建设水资源节约型社会的一项重要任务和战略目标。本文重点对国内外常见的几种主要的水资源管理模式的内涵及其管理手段和功能特征等进行了比较分析和研究,在此基础上,探讨了我国水资源管理模式的创新与发展思路,初步提出：建立以流域为单元的水资源生态系统综合管理模式是我国未来水资源管理制度改革的重要发展方向。 相似文献

Most countries along the route of the “Belt and Road” initiative are faced with a shortage of water resources. However, successful implementation of the initiative depends on water availability to support economic and social development. We designed a water resources carrying capacity evaluation index system, assigned grades and weights to each evaluation index and calculated a water resources carrying index for the 65 countries along the route. We used virtual water theory to analyze China’s net virtual water import from key bulk agricultural products through international trade. For more than half of the countries along the route, their water resources will be unable to support the economic development that will be necessary for fulfilling the goals of the Initiative. As a country with insufficient water resources carrying capacity, China is a net virtual water importer in the virtual water trade. This virtual water trade can improve China’s water resources support capacity, and ensure China’s water and food security for the future. 相似文献

黑河流域2004-2010年水足迹和水资源承载力动态特征分析 总被引：6，自引：0，他引：6
中国是水资源短缺国家,水资源时空分布不均,水资源已成为制约中国社会经济可持续发展的重要因素。利用生态足迹法构建了黑河流域农业用水、工业用水、城镇公共用水、生活用水和生态环境用水5个二级水资源账户,并利用水资源负载指数,研究了黑河流域2004—2010年水资源承载力、水足迹和水资源负载动态特征。结果表明,黑河流域水资源承载力从2004年的16.36 hm2增加至2010年的24.40 hm2;总水资源生态足迹从2004年的571.81 hm2减少至2010年的486.73 hm2;而水资源生态赤字从2004年的555.45 hm2下降至2010年的462.33 hm2;黑河流域水资源负载指数高,水资源开发潜力很小;黑河流域水资源承载力增加与降水量有密切关系。 相似文献

研究区域水资源不平衡背后的“俱乐部趋同”现象,对于水资源调节以及水资源均衡配置具有重要的理论和实践意义。基于2004-2015年我国31个省（市、区）的人均水资源数据,利用扩展的马尔科夫链模型检测了不同时长下我国省际水资源量分布的俱乐部趋同现象,并分析了其时间特征。结果表明：即使在5 a的时间积累下,我国人均水资源量仍存在着明显的俱乐部趋同现象,高水平和低水平地区水资源量分布高度固化,且俱乐部趋同程度在2008年开始向恶化的趋势发展,可见当前我国区域水资源调节力度有待进一步加强。最后论文根据各地区人均水资源在考察期各年所属俱乐部类型、类型转移频率等因素对各地区进行了分类,以对区域水资源调节提供支持和参考。 相似文献
