雨水收集设施等水工程日益得到应用,需要解决雨水收集设施等水工程设施收集的水资源的所有权。因大气降水是一种自由资源,不属于《宪法》中的"水流"或《水法》中的"水资源"的范畴,雨水收集设施等水工程设施收集的水资源所有权不能适用《宪法》、《水法》的规定,而是取决于雨水收集设施等水工程设施的所有权。雨水收集设施等水工程设施不是土地的组成部分,所有权包括国家所有、集体所有、其他组织和个人所有等形式,因此,雨水收集设施等水工程设施收集的水资源所有权自然包括国家所有、集体所有、其他组织和个人所有。但水工程设施不是公益性、大中型的水利设施,允许其他投资主体投资,其所有权应以集体、个人所有为主要形式 相似文献

地下水资源为储存和流动在含水系统中、对人类有利用价值的地下水,包括淡水资源和矿水资源两部分。饮用和生活用水、工业用水和农业用水,常以地下淡水资源作为供水源。因此,人们在讨论地下水资源时,往往容易理解为地下水资源就是淡水资源.忽视了地下矿水资源。实质上地下矿水资源是地下水资源的重要组成部分,在国民经济中具有非常重要的理论意义和实际意义。 相似文献

本文所讨论的水资源是指在现阶段技术经济条件下可以被人类利用的淡水资源,特别是指地表水和浅层地下水.它具有可重复利用和时空分布不均衡的特性,是一种人类必需的而不可替代的环境因子.我国宪法规定:“水资源是属于国家所有即全民所有的自然资源,国家保障它的合理利用,禁止任何组织或个人用任何手段侵占或者破坏它”.《中华人民共和国水法》第34条中明确规定“对城市中直接从地下取水的单位,征收水资源费;其他直接从地下或江河、湖泊取水的可以由省、自治区、直辖市人民政府决定征收水资源费”.党中央、国务院在《关于出席联合国环境与发展大会的情况及有关对策的报告》中也指出:“各级政府应更好地运用经济手段来达到保护环境的 相似文献

Abstract: Assessment of long‐term impacts of projected changes in climate, population, and land use and land cover on regional water resource is critical to the sustainable development of the southeastern United States. The objective of this study was to fully budget annual water availability for water supply (precipitation ? evapotranspiration + groundwater supply + return flow) and demand from commercial, domestic, industrial, irrigation, livestock, mining, and thermoelectric uses. The Water Supply Stress Index and Water Supply Stress Index Ratio were developed to evaluate water stress conditions over time and across the 666 eight‐digit Hydrologic Unit Code basins in the 13 southeastern states. Predictions from two Global Circulation Models (CGC1 and HadCM2Sul), one land use change model, and one human population model, were integrated to project future water supply stress in 2020. We found that population increase greatly stressed water supply in metropolitan areas located in the Piedmont region and Florida. Predicted land use and land cover changes will have little effect on water quantity and water supply‐water demand relationship. In contrast, climate changes had the most pronounced effects on regional water supply and demand, especially in western Texas where water stress was historically highest in the study region. The simulation system developed by this study is useful for water resource planners to address water shortage problems such as those experienced during 2007 in the study region. Future studies should focus on refining the water supply term to include flow exchanges between watersheds and constraints of water quality and environmental flows to water availability for human use. 相似文献

Abstract: A decision support system for sustainable water resources management in a water conflict resolution framework is developed to identify and evaluate a range of acceptable alternatives for the Geum River Basin in Korea and to facilitate strategies that will result in sustainable water resource management. Working with stakeholders in a “shared vision modeling” framework, sustainable management strategies are created to illustrate system tradeoffs as well as long‐term system planning. A multi‐criterion decision‐making (MCDM) approach using subjective scales is utilized to evaluate the complex water resource allocation and management tradeoffs between stakeholders and system objectives. The procedures used in this study include the development of a “shared vision model,” a simulated decision‐making support system (as a tool for sustainable water management strategies associated with water conflicts, management options, and planning criteria), and the application of MCDM techniques for evaluating alternatives provided by the model. The research results demonstrate the utility of the sustainable water resource management model in aid of MCDM techniques in facilitating flexibility during initial stages of alternative identification and evaluation in a basin suffering from severe water conflicts. 相似文献

Abstract: Managing drought in agriculture has taken on growing importance as population growth and environmental concerns place increasing pressures on agricultural water use. One alternative for agricultural water resource management in areas of recurrent drought is allocation through market mechanisms. While past research has aimed to explain why farmers are reluctant to participate in already established water markets, this research seeks to identify the appropriate market mechanism given farmers’ preexisting attitudes toward water markets. Statistical analysis of survey data from 166 farmer interviews in the Rio Grande Basin indicate that farmers are significantly more likely to participate in short‐term water mechanisms, such as spot water markets and water banks than in permanent transfer mechanisms, particularly those that fully separate water rights from land. In sharp contrast to expectations, the choice of market mechanism did not differ significantly between farmers based on their a priori intention to buy, sell or both buy and sell in these markets. Choice of market mechanism also did not differ among farmer types although small, lifestyle or hobby farmers clearly preferred spot water markets to other types of short‐term mechanisms. Evaluating these attitudes a priori may help to design more suitable water market mechanisms for the basin. 相似文献

本文讨论了区域水资源的评价问题.无论是地表水、地下水,还是土壤水都是来源于大气降水,降水资源才是区域总水资源;同时讨论了区域水资源的平衡原理.降水资源转化了截留水、地表水、土壤水和地下水4项水资源.该文对这2种不同的水体进行了深入讨论,着重论述了土壤水资源的概念及其特征.并对潜水蒸发和水资源的价值问题提出了看法. 相似文献

Severe drinking water shortage affects all resident of the Kabul river basin. Two and a half decades of civil war in Afghanistan
(it began in late 1978) have resulted in widespread environmental degradation and water resource development throughout the
country. The war has already finished and, therefore, water resource management for supplying water is one of the most important
tasks for Afghanistan’s government. The Kabul river basin which is the most populated area in the country is located in the
eastern part of Afghanistan. This article deals with the water resource properties of the Kabul river basin and also water
demand in the important cities of the basin, such as Kabul, the capital and the largest city in the country. Also a few suggestions
for providing water for domestic and agriculture purposes in short term, medium time and long term have been discussed. 相似文献

Abstract: Building water mass balances were performed for one 150‐story conventional building scenario for comparison with three scenarios of the 2020 Tower, a hypothetical 150‐story high‐rise building with on‐site wastewater treatment and reuse. To ensure that the assumptions for the hypothetical building are appropriate, a one‐year water balance was also conducted of the existing 27‐story Solaire building that partly closes the water/wastewater loop, meters major water flows and implements low‐flow/water conserving fixtures and appliances. For comparison, a conventional 27‐story building scenario with the same low‐flow/water conserving fixtures as the Solaire but no water reuse was also assessed. The mean daily indoor water use in the Solaire was 246 l/(d cap) which exceeds mean daily water use found in the literature. The water mass balances showed that an urban high‐rise building needs another source of water even when potable reuse water is produced because of losses during water end use and treatment (i.e., evaporation, water in treatment residues). Therefore, water conservation (i.e., modification of human behavior) and water efficiency improvements (i.e., equipment, appliances and fixtures) are important major factors in reducing the municipal water needed in all scenarios. 相似文献
