Archipelagos and networks: urbanization and water privatization in the South

This paper examines the interrelationship between urbanization and water supply privatization in cities in the global South. The purpose of the paper is not to evaluate the impacts of privatization; rather, the paper analyses the differences in pathways and modes of water supply privatization, focusing on urban and contrasting with rural areas. A distinction is drawn between privatization (organizational change) and commercialization (institutional change) of water supply. Emphasis is placed upon the interrelationship between regulatory change (a shift from public to private management of water supply systems), human use of and access to water, and urban waterscapes. In contrast to metaphors of 'networks' so often applied in analyses of water management, the 'archipelago' is posited as a metaphor which better captures the complex overlapping strategies of water supply provision in urban areas in the South. Building on this metaphor, and in response to the 'public–private' dualism often invoked in studies of privatization, the paper outlines an alternative typology of water management in urban areas in the South. This typology foregrounds the concepts of the territorialization of corporate power as a means of understanding the articulation between privatization and urbanization processes in the South.     

汾河口傍河水源地激发补给量研究

Eco-environment range in the source regions of the Yangtze and Yellow rivers

Based on geographical and hydrological extents delimited, four principles are identified, as the bases for delineating the ranges of the source regions of the Yangtze and Yellow rivers in the paper. According to the comprehensive analysis of topographical characteristics, climate conditions, vegetation distribution and hydrological features, the source region ranges for eco-environmental study are defined. The eastern boundary point is Dari hydrological station in the upper reach of the Yellow River. The watershed above Dari hydrological station is the source region of the Yellow River which drains an area of 4.49×104 km2. Natural environment is characterized by the major topographical types of plateau lakes and marshland, gentle landforms, alpine cold semi-arid climate, and steppe and meadow vegetation in the source region of the Yellow River. The eastern boundary point is the convergent site of the Nieqiaqu and the Tongtian River in the upstream of the Yangtze River. The watershed above the convergent site is the source region of the Yangtze River, with a watershed area of 12.24×104 km2. Hills and alpine plain topography, gentle terrain, alpine cold arid and semi-arid climate, and alpine cold grassland and meadow are natural conditions in the source region of the Yangtze River.     

夏塞地区银、锡多金属矿成矿规律新认识

夏塞地区是西南三江(金沙江、澜仓江、怒江)地区东缘的一个重要成矿带，带内银、锡矿产责源十分丰富。本文认为其成矿物质来源于花岗岩体和地层，构造和岩体是区内的主要控矿因素，地壳演化与成矿作用关系十分密切，矿床类型为分布于岩体内接触带的矽卡岩型矿床和分布于岩体外接触带的热液型矿床。     

公婆泉盆地局部排泄源氧化还原属性与铀矿化关系探讨

在系统分析公婆泉盆地地质背景、水文地质条件的基础上，对该区局部排泄源氧化还原属性与铀矿化的关系进行了探讨。研究结果表明，局部排泄源的存在对铀矿化具有重要作用，当局部排泄源属于还原性质时，铀矿体常常分布于该排泄源上游；若属氧化性质，排泄源铀矿体通常位于其下游或附近。公婆泉盆地存在相对氧化和相对还原的二种局部排泄源，北骆驼泉区的沙泉沟与平沙地、麻黄沟、北骆驼泉沟排泄源之间应为有利的铀矿化地段。     

伊犁盆地石炭系—二叠系含油气性特征

伊犁盆地是在前震旦系基础上发展形成的双层结构盆地，即内裂谷盆地—山间陆相盆地。经多次造陆运动后，盆地内普遍缺失震旦系、下古生界、泥盆系、下三叠统和白垩系。盆地内的生油层主要为海相石炭系阿克沙克组、也列莫顿组，陆相二叠系院山萨依组、塔姆其萨依组。生油中心主要位于伊什基里克山—脱勒斯拜克山以北的湖盆区内。储层主要以二叠系、三叠系和保罗系的碎屑岩为主。伊犁盆地虽然经历了多期构造运动的影响，地质结构更加复杂，沉积中心的不断西移，但仍然在中新生代地层的地表及井下发现大量油气显示，表明该盆地具备生储油能力。该盆地有利与不利因素并存，对盆地的进一步勘探应加强基础研究工作，以避免盲目投入。
