用科学发展观指导地下水监测工作 总被引:1,自引:0,他引:1
陶庆法 《水文地质工程地质》2007,34(1):I0001-I0001
目前,国土资源部门建设的地下水监测网点已基本覆盖了全国主要地下水开采区和主要地下水类型及含水层系统,初步形成了国家、省、地(市)三级地下水监测网络,建立了专门从事地下水监测与研究的专业机构,培养造就了一支素质优良的专业队伍。但是,我国地下水监测工作与经济社会发展的需求还不相适应,难以满足现代化建设的需要,存在地下水监测点数量少、控制精度低、监测设施简陋、监测技术方法和手段落后等需要迫切解决的问题。[第一段] 相似文献

阿克苏地区位于新疆西部,天山南麓,塔里木盆地北缘,地下水动态监测系统不够完善,通过实施地下水监测站网建设项目,地下水监测站网布设日趋合理。监测站在阿克苏河、台兰河、渭干河、库车河等冲洪积平原区、乌什县河谷、拜成盆地、柯坪盆地和阿恰平原这几块地质单元上都有分布,可比较全面的反映阿克苏地区境内主要地下水开发利用区的埋深、水位变化特征。通过对阿克苏地区地下水监测工作进行探讨,重点对地下水监测站网建设和日常监测工作开展情况进行了分析。结合近几年该地区地下水位年度监测成果,对区域地下水位状况和年内地下水动态变化特征分析,大致可以看出区域内地下水总体呈下降趋势,冬季灌溉期结束后地下水潜水水位最高,3-4月份春灌开始后,地下水位总体下降,6、7月份受地表来水、灌溉等补给的影响,地下水又有一次集中上升的现象。研究结果为该区域地下水中长期开发利用与管理保护工作提供了理论依据。 相似文献

为落实国家地下水监测工程与地下水质监测任务,实现对河南省地下水动态的有效监测,以及对河南省平原、盆地及岩溶山区地下水动态的区域性监控。国家地下水监测工程和河南省地下水监测工程在河南省监测区共布设国家级地下水监测站点485个,省级地下水自动监测站点387个。监测区控制面积10.86万平方千米,主要监测层位浅层潜水(微承压水)、承压第Ⅰ含水层组地下水(中深层地下水)、承压第Ⅱ含水层组地下水(深层地下水)、承压第Ⅲ含水层组地下水(超深层地下水)、岩溶水、裂隙水,项目工程的建设完成,基本上完善了河南省地下水监测专业站点,提升了对全省区域地下水、国家重大工程沿线及地下水污染高风险区的监控能力,确保了及时、准确、全面的获取地下水动态信息,从而满足科学研究和社会公众对地下水信息的基本需求。根据监测成果将河南省浅层地下水划分为6个埋深分区,埋深区间在1.41~52.68m,平均埋深11.93m。划出降落漏斗两处,划分浅层地下水化学类型11种,主要为HCO3·Cl-Ca型;水质分析综合评价结果显示以Ⅳ类和Ⅴ类水为主。 相似文献

Groundwater status and associated issues in the Mekong-Lancang River Basin: International collaborations to achieve sustainable groundwater resources 下载免费PDF全文

Groundwater is an important and readily available source of fresh water in the Mekong-Lancang River Basin. With a rapid population growth and increasing human activities, an increasing number of countries in the Mekong-Lancang River Basin are experiencing depleted and degraded groundwater supplies. In transboundary river basins, such as the Mekong-Lancang River, prioritizing the use of the shared aquifer by one riparian government may affect the opportunities of other riparian governments and lead to potential water conflicts between neighboring countries. To promote the sharing of strategies and information for the sustainable and equitable use of water resources of the shared basin, international collaborative workshops on groundwater resources have been organized for all Mekong-Lancang River countries. These workshops provide an opportunity to communicate and discuss nationally sensitive issues on groundwater by the associated countries, with topics covering multiple aspects of groundwater, such as the groundwater status in the basin, quality issues, water use conflicts, hydrological information gaps, management policies and capacity building for successful water resource management. Consensus has been reached by all countries on the importance of catchment-based groundwater management and the need for close communication among the countries. Strategies for managing transboundary aquifer issues must foster international collaboration based on the regional network, influence national networks and enhance the capacity to building maps and monitoring systems based on associated databases. The sustainability of water resources cannot be achieved without the integrated involvement and contributions by multiple countries and various stakeholders. Therefore, collaborative workshops provide a great opportunity to further our understanding of the hydrologic processes of the Mekong River Basin, share the benefits of the aquifer and provide a strategy and vision for sustainable water resource management in the Mekong-Lancang River countries. 相似文献

Groundwater, as a precious resource hidden underground, is an important component of the global water system. Transboundary
aquifers containing substantial amount of groundwater often carry crucial ecological and social implications. Yet, it is unfortunate
that transboundary aquifers have hardly been in the forefront of political and scientific discussions, and have not received
due attention by policymakers. This article attempts to summarize the investigation on the eight transboundary aquifers that
China shares with the neighboring countries. An overview on the groundwater resources in China, including its distribution,
exploitation and challenges is also provided. Hydrogeological condition of the Heilongjiang-Amur River Basin aquifer, which
is one of the eight major aquifers, is further elaborated. Cooperative activities carried out by China and Russia on monitoring
and management of this aquifer are also presented. 相似文献

Monitoring of regional groundwater levels provides important information for quantifying groundwater depletion and assessing impacts on the environment Historically,groundwater level monitoring wells in Beijing Plain,China,were installed for assessing groundwater resources and for monitoring the cone of depression.Monitoring wells are clustered around well fields and urban areas.There is urgent need to upgrade the existing monitoring wells to a regional groundwater level monitoring network to acquire information for integrated water resources management.A new method was proposed for designing a regional groundwater level monitoring network.The method is based on groundwater regime zone mapping.Groundwater regime zone map delineates distinct areas of possible different groundwater level variations and is useful for locating groundwater monitoring wells.This method was applied to Beijing Plain to upgrade a regional groundwater level monitoring network. 相似文献

Sanjiang Plain-Amur River Basin aquifer is the aquifer shared by China and Russia, which is of great significance to water sources management for both countries, acting as a focused area by China and Russia. In this paper, the hydrogeological characteristics of the Sanjiang Plain-Amur River Basin is studied, aiming at understanding the differences as well as similarities of aquifer classification, chemical characteristics of groundwater, quantity of groundwater and groundwater evaluation methods of two countries, which will lay a solid foundation to further holistic study of the trans-boundary aquifer in the Sanjiang Plain-Amur River Basin. 相似文献
