我国水污染事件频发,河湖功能退化等问题相继出现。为提高河湖治理效率,我国政府创新提出河长制以落实地方党政领导河湖管理保护主体责任。河长制的推行对促进河湖系统保护、改善整体水环境及保障河湖功能永续利用具有常重要意义。行政河长制自推行以来便伴随着关于其"人治化"的质疑,同时传统的行政河长制下河长所肩负的多任务委托代理关系对其治理能力提出了更高要求,民间河长制的并行可减轻行政河长原有治理负担,同时借助其天然的亲民性,民间河长制的推行可有效促进河湖治理效果的提升。因此提倡,在全面推行行政河长制的同时,应配以由社会力量组成的民间河长制,并实现民间河长制的垂直化以与行政河长制双轨并行,二者相互补充,可实现河湖治理"1+12"的效果。通过论证推行双轨河长制的必要性与可行性、明确界定行政河长与民间河长的责任分工、建立区域内部及跨区域的双重协商平台与内外部监督途径相结合的有效监督机制,构建双轨河长制以实现河湖有效治理目标。  相似文献

After the independence of Central Asian countries, many international projects have been launched to promote water users’ inclusion into the water management at different levels. The aim of such projects is to achieve sustainable water management through inclusion of interests of different groups on day-to-day water management. Although IWRM in Central Asia has been already promoted for a decade, there are only a few examples of the implementation in real life situations.The Integrated Water Resources Management in Ferghana Valley (IWRM FV) is a pilot project on implementing integrated water resources management elements at the main canal levels and below. The experience gained from IWRM FV project and lessons learnt could be useful for the national and international organizations for their future work on IWRM implementation at the different regions of Central Asia.IWRM FV project has been active since 2001 in the Ferghana Valley, one of the largest irrigated areas of Central Asia. The project has promoted and implemented participatory irrigation management for three pilot canals. This paper presents the process of implementation and some preliminary outcomes of the IWRM VF project.  相似文献

水利工程供的水,不但用于农业,而且逐步转向供工业和城镇人民生活用水。工程投资也是多渠道、多方面集资。水利工程的供水效益,不但计算它的社会效益,而且要进行财务评价,对于水管单位来说,这项工作更为重要。水利工程供工业和城镇生活用水,它的财务评价应如何进行,目前还没有一个完整的计算方法。本文根据《建设项目经济评价方法与参数》中的原则及水利工程特点,结合具体工程实例,提出了水利供水工程财务评价的方法和步骤。  相似文献

The present paper presents the SAFIR project (www.safir4eu.org), which addresses two fundamental problems that over the past decade increasingly have become concerns of the general public: the one problem being the jeopardizing of safety and quality of our food products, while the other being the increasing competition for clean freshwater. The SAFIR project has a multi-disciplinary approach, which integrates the European as well as the global dimension of the EU-policy on food quality and safety. The main driving force behind the project idea is new research results that demonstrated that scheduled uneven irrigation patterns can increase the water use efficiency as well as the quality of vegetable crops. Furthermore, recent innovations in the water treatment and irrigation industry have shown potential for the use of low quality water resources, such as reclaimed water or surface water in peri-urban agriculture, for irrigation of vegetable crops without threaten food safety and quality. The results of SAFIR were achieved from field experiments in Europe and China and modeling activities both at field and farm scale. The present article describes the structure of the project and highlights the main findings and recommendations of the project described in detail in already published papers and in accompanying papers in this special issue.  相似文献

This study analyzes the effects of irrigation modernization on water conservation, using the Riegos del Alto Aragón (RAA) irrigation project (NE Spain, 123354 ha) as a case study. A conceptual approach, based on water accounting and water productivity, has been used. Traditional surface irrigation systems and modern sprinkler systems currently occupy 73% and 27% of the irrigated area, respectively. Virtually all the irrigated area is devoted to field crops. Nowadays, farmers are investing on irrigation modernization by switching from surface to sprinkler irrigation because of the lack of labour and the reduction of net incomes as a consequence of reduction in European subsidies, among other factors. At the RAA project, modern sprinkler systems present higher crop yields and more intense cropping patterns than traditional surface irrigation systems. Crop evapotranspiration and non-beneficial evapotranspiration (mainly wind drift and evaporation loses, WDEL) per unit area are higher in sprinkler irrigated than in surface irrigated areas. Our results indicate that irrigation modernization will increase water depletion and water use. Farmers will achieve higher productivity and better working conditions. Likewise, the expected decreases in RAA irrigation return flows will lead to improvements in the quality of the receiving water bodies. However, water productivity computed over water depletion will not vary with irrigation modernization due to the typical linear relationship between yield and evapotranspiration and to the effect of WDEL on the regional water balance. Future variations in crop and energy prices might change the conclusions on economic productivity.  相似文献

The purpose of this work is to contribute to the development of a combined approach to evaluate irrigated areas based on: (1) irrigation performance analysis intended to assess the productive impacts of irrigation practices and infrastructures, and (2) water accounting focused on the hydrological impacts of water use. Ador-Simulation, a combined model that simulates irrigation, water delivery, and crop growth and production was applied in a surface irrigated area (1213 ha) located in the Bear River Irrigation Project, Utah, U.S.A.. A soil survey, a campaign of on-farm irrigation evaluations and an analysis of the database from the Bear River Canal Company and other resources were performed in order to obtain the data required to simulate the water flows of the study area in 2008. Net land productivity (581 US$ ha−1) was 20% lower than the potential value, whereas on-farm irrigation efficiency (IE) averaged only 60%. According to the water accounting, water use amounted to 14.24 Mm3, 86% of which was consumed through evapotranspiration or otherwise non-recoverable. Gross water productivity over depleted water reached 0.132 US$ m−3. In addition, two strategies for increasing farm productivity were analyzed. These strategies intended to improve water management and infrastructures raised on-farm IE to 90% reducing the gap between current and potential productivities by about 50%. Water diverted to the project was reduced by 2.64 Mm3. An analysis based on IE could lead to think that this volume would be saved. However, the water accounting showed that actually only 0.91 Mm3 would be available for alternative uses. These results provide insights to support the decision-making processes of farmers, water user associations, river basin authorities and policy makers. Water accounting overcomes the limitations and hydrological misunderstandings of traditional analysis based on irrigation efficiency to assess irrigated areas in the context of water scarcity and competitive agricultural markets.  相似文献
