采煤对海流兔流域大气降水-地表水-地下水-矿井水转化关系的影响北大核心CSCD

煤矿开采使流域水文地质条件发生改变,研究采煤影响下流域降水-地表水-地下水-矿井水转化关系对揭示区域水循环过程意义重大。以海流兔流域为研究区,利用数理统计法、Piper三线图和氢氧同位素关系图等方法,分析采煤影响下降水-地表水-地下水-矿井水的转化关系。结果表明:在煤矿开采影响下采矿区地表水中SO_(4)^(2-)、Na^(+)、Mg^(2+)等含量增幅较大;流域降水、地表水与地下水转化关系以地表水下渗补给地下水为主,平均贡献率为56.7%;矿区及以下流域海流兔与纳林河不同水体间的转化关系仍以地表水补给地下水为主,与上游天然流域相比平均贡献率分别增至69.3%和59.4%;矿井水主要来源为上覆萨拉乌苏组地下水,补给比率为72.4%,煤矿开采使上覆含水层地下水向采空区汇流速度增大。

The evolution and enlightenment of water resources accounting from accounts to balance sheet

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.

Research progress of socio-economic water cycle in China

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.

Water demand management and the quest for sustainability

This paper problematises positivist framings of water demand management (WDM) that define the average‐water‐user. Through a situated, case‐study account undertaken in suburban Auckland, we highlight variable social and cultural underpinnings of domestic water use. Activities that are commonly the focus of WDM are shown to be embedded elements of life around which relationships, affects and futures are woven. As a consequence, myopically focusing on the technical–managerial mediation of what are socionatural relations reduces prospects to achieve intended policy outcomes. Reframing WDM as a hydrosocial process provides a basis for water providers to develop more culturally appropriate water management.     

论水权的性质及构成

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。     

水量统一调度以来黄河内蒙古河段耗水量分析

黄河水量统一调度始于1999年3月,本次对1999-2011年黄河内蒙古河段引水和退水的年内、年际变化以及引排比关系进行了分析;利用遥感图片,核查了黄河干流石嘴山—头道拐河段的引退水口门;分别采用引退水法和水量平衡法计算了黄河内蒙古河段的引黄耗水量。结果表明:该研究时段内蒙古河套灌区退水量与引水量的比值平均为0.16,呈现逐年增大的趋势,引退水关系比较好,存在"大引大排"现象;引退水法年平均耗水量为75.44亿m3,年际变化相对比较平缓;水量平衡法年平均耗水量为56.72亿m3,年际变化非常明显;两种方法耗水量差别明显的原因之一是颁证引退水口门与实际引退水口门数量不相同。
