万家寨引黄工程太原供水区地下水资源保护   总被引:2,自引:1,他引:1       下载免费PDF全文
在分析万家寨引黄工程太原供水区地下水开发利用现状的基础上,指出地下水超采引起的环境水文地质问题有:泉水断流;区域地下水水位下降并形成大面积降落漏斗,含水层疏干或产水量减少;由于地下水水位下降,导致地下水水质污染加重及地面沉降。提出应对供水区地下水资源加强保护,防止污染;压缩超采,划定禁采区和限采区;建立监测与管理信息系统,利用经济杠杆,全面节流,优化调配,逐步实现引黄水和本地水资源的联合运用。  相似文献

加强地下水管理的思路与对策   总被引:4,自引:2,他引:2  
孙雪涛 《中国水利》2007,(15):17-18,33
地下水是水资源不可分割的组成部分,是生态和环境的主要控制因素。作为我国北方地区的主要供水水源,地下水开发规模不断增加,超采以及因超采引发的生态与环境问题日趋突出,南方部分地区特别是沿海和重要城市区,地下水开发带来的问题也越发严重。今后一个时期,要全面推进地下水资源管理,对水资源进行统一调查评价,统一规划和统一调配,加强超采区的治理,遏制地下水超采,加强地下水水质保护,防止地下水污染,逐步实现地下水采补平衡,改善生态与环境,实现地下水资源的可持续利用。  相似文献

本文以鄯善县为研究区域,以2010年水平年的数据为依据,对研究区进行了水资源利用情况分析和水均衡计算,评价不同程度退耕方案下规划水平年2020年地下水可开采量,计算出不同区域不同方案下的地下水超采量。结果表明:尽管大幅度地采取退耕还水措施(高方案),鄯善县的水资源也不能满足其社会经济发展的用水需要,南盆地地下水仍有超采。为尽快治理南盆地地下水超采现状,最重要的是要实行鄯善县产业发展模式转型,或跨流域调水,以实现鄯善县地下水水资源的可持续利用。  相似文献

地下水功能区划分浅谈   总被引:10,自引:2,他引:8  
简要介绍了我国地下水面临的主要问题:资源枯竭、生态功能退化、环境地质灾害加剧。根据地下水系统具有的资源供给、生态环境保护、地质安全保障这三大功能,分析了地下水功能与当前地下水面临的诸多问题的关系,提出将地下水分布区划分成四类一级功能区,即开发利用区、生态环境保护区、地质灾害防治区和保留区,分析了地下水功能区和地下水超采区的关系,建议将地下水功能区和地表水功能区联合起来,构成水资源统一管理的技术平台。指出地下水保护的程序是:进行地下水功能区划,建立地下水功能区评价指标体系,研究地下水保护的标准体系,制定和实施地下水系统保护方案,加强地下水监测和管理。  相似文献

This study aims at developing Groundwater Quality Indices (GQIs) that constitute a reliable tool in defining aquifer vulnerability. For this purpose, water quality sampling campaigns were conducted on 60 groundwater wells during most vulnerable periods of early and late summer to ensure the representativeness of the targeted GQI under worst case conditions. The samples were tested for various water quality indicators, which were then used to develop the GQIs through GIS-based mapping with spatial geostatistical analysis. The results contribute in filling a gap in GQI definition and form a basis for planning effective water quality management towards sustainable exploitation of groundwater resources particularly during summer periods when recharge is limited.  相似文献

南水北调东、中线一期工程对受水区生态环境影响分析   总被引:1,自引:1,他引:0  
为了定量回答南水北调工程对受水区生态环境的影响,对2000年以来东、中线一期工程受水区生态环境状况和所辖72座设市城市用水状况进行了统计分析,得出受水区生态环境和地下水循环更新能力正在退化;进而采用水量平衡分析方法,从一期工程对缓解受水区干旱程度、减少地下水超采、置换城市挤占农业用水量、调水可增加农业和环境用水量等方面定量分析了一期工程对受水区生态环境的改善作用。结果表明,一期工程对受水区城市供水和农业生态环境改善具有较显著的作用,但不能从根本上解决地下水超采问题;充分发挥一期工程效益需节水、调水、治污三项措施同步实施。  相似文献

This paper gives an overview of the geophysico-chemical groundwater conditions in Sri Lanka and the associated contemporary management challenges. Groundwater is extensively used in Sri Lanka today, for agriculture, domestic use and industry/tourism. Groundwater access, availability and vulnerability are governed by six major types of aquifer systems of which the most prevalent is the regolith aquifers in the central hard rock areas of the island. Uncontrolled groundwater use and contamination or natural poor quality are leading to access limitations and health concerns. The tsunami severely affected groundwater in the coastal areas and functioned as a wake-up call to further emphasize the importance of groundwater for life-supporting functions. Despite an emerging awareness, groundwater management is in its infancy, with the attitude of groundwater development still not converted into an approach of active management. The role of groundwater in achieving sustainable development and in the development of appropriate water management institutions needs to be highlighted and specifically addressed in policy discussions.  相似文献

In this paper, a modeling framework by combining system dynamic (SD) model and optimal allocation model was developed to study water resources vulnerability and optimal water use structure, and the framework was applied in the middle reaches of Heihe River basin, northwest of China. The SD model could describe the dynamical change of water resources vulnerability by integrating water resources with socio-economic effect. The sensitivity analysis of SD model was then conducted to design appropriate scenarios for finding out the optimal development pattern, and based on which, an integrated water-saving scenario with lower water resources vulnerability was identified for optimization modeling. Then, an inexact fuzzy-parameter two-stage programming (IFTSP) model was developed and applied to optimize water use structure among industries under uncertainties. This study addresses the water resources vulnerability analysis in considering both water resources system and socio-economic system. Water resources vulnerability analysis was combined with optimization model to make adaptive water resources management plans. And the optimal allocation schemes under lower water resources vulnerability are more advantageous for regional sustainable development.  相似文献

The political boundaries between the Palestinian and Israelismake the water issues critical and sensitive. Groundwater is theprimary source for the Palestinian in the West Bank. Although, there are many studies on the shared surface resources (Jordan River Basin), there are few studies on the groundwater shared resources between the Palestinians and Israelis.There are three primary groundwater basins underlying the West Bank (Eastern, Northeastern and Western Basins) as shown in Figure 1. Both the Northeastern and Western basins are shared between Israelis and Palestinians. The Palestinians have a limited access to the Northeastern Basin and strictly limited access to the Western Basin. In addition to the quantity of available water resources, thequality of water is emerging as a critical issue. Threats to ground water quality include disposal of untreated wastewater, increasing salinity due to agricultural activities and intrusion of native groundwater of poor quality. Widespread use of herbicides and pesticides also represent a threat to drinking water supplies.The Declaration of Principles, signed in Washington D.C in 1993,was a major step toward resolution of the political conflict between the Israelis and Palestinians. However, the water issue is part of the final status negotiations, which still unresolved.As resolution to political conflict is pursued, it is clear that water resources management issues remain at the forefront becauseof the transboundary nature of the hydrologic regime. Cooperative management on the technical level appears to be the only alternative to further conflict and degradation of the region's scare water resources. This article will study the impact of the transboundary resources on both sides and explore some of the most significant groundwater management issues facing both the Palestinians and Israelis.  相似文献

A modeling system was developed to evaluate the sustainability of water resources management strategies in the two major basins of Thessaly Region in Greece, namely the Pinios River and the Lake Karla basins. The intense and extensive agriculture of water demanding crops, such as cotton, and the absence of reasonable water resources management have lead to a remarkable water demand increase, which is usually fulfilled by the over-exploitation of groundwater resources. This unsustainable practice has deteriorated the already disturbed water balance and accelerated water resources degradation. The modeling system consists of a hydrological model, a reservoir operation model and methods for the estimation of water demands. The study area was sub-divided into sub-basins and water balance analyses were performed for each sub-basin and each control node of the system for a number of water resources management strategies. Four strategies of hydro-technical project development were coupled with two strategies of groundwater withdrawal and three water demand strategies. In total, more than 24 water management strategies were evaluated. The results showed that, under the existing water resources management, the water deficit of the Pinios River and Lake Karla basins is very large. However, the development of proposed hydro-technical projects in the Pinios River basin coupled with water demand management measures, like improvement of existing water distribution systems, change of irrigation methods, and changes of crop cultivation could alleviate the problem and lead to sustainable and ecological use of water resources in the study area.  相似文献

对国外河流健康问题的初步认识   总被引:28,自引:1,他引:27  
刘恒  涂敏 《中国水利》2005,(4):19-22
人类在开发利用流域水资源的过程中,由于保护不够或滥加利用,一些河流出现污染、断流等现象,影响了河流的自然和社会功能,失去了河流的自身价值,危及河流的健康生命.河流健康生命问题本质上是由于经济快速发展的需要,过度开发和轻视保护水资源所造成的,因此一些发达国家较早地关注河流健康的问题.澳大利亚的新南威尔士州成立了"健康河流委员会".针对国外在河流健康方面所涉及的基本概念、衡量标准、评价方法、保护措施等进行了综合归纳,并搜集了一些维护河流健康的个例.  相似文献
