全国矿产资源规划信息数据库及管理系统的构建

随着矿产规划管理信息的逐渐增多和矿政管理部门的需求不断提高,本文根据规划管理的业务需求以及第二轮的矿产资源规划标准,建立了全国矿产资源规划信息数据库管理系统。通过Oracle 10g建立矿产资源规划信息数据库,并通过ArcGIS Engine构建管理系统,实现了全国矿产资源规划信息的整合与共享,为矿产规划管理的科学化、精细化提供了依据。

BUILDING A COLONIAL RESOURCE MONOPOLY: THE EXPANSION OF SULPHUR MINING IN NEW SPAIN, 1600–1820*

The discovery, extraction, and monopolistic control of key natural resources was a priority of New Spain's colonial administration. Managing the region's abundant resources, however, often proved difficult for the Spanish Crown. Human and environmental challenges impeded protoindustrial growth and development, and monopolistic control of resources often met resistance. In this article I examine these processes in the context of New Spain's little‐known monopoly on sulphur—a yellow, powdery mineral the Crown jealously guarded as its own. Sulphur was critical for gunpowder and explosives production, yet the Crown often failed to produce enough of it to meet the growing demand by its military and the silver blast‐mining industry. Colonial documents reveal administrators’ attempts to improve sulphur production through reform measures, which included advising sulphur miners on how to discover sulphur deposits and, eventually, how to develop their mines. Efforts to improve sulphur production were moderately successful, although the process was messy and inefficient.     

Geography,the Integrating Discipline: Explaining China's Population-Driven Geopolitics to Students

Abstract

This article demonstrates geography's role as an integrative discipline and its utility in connecting students to the world around them. A case study links China's demography and its geopolitics to the lives of U.S. students. The relationship of China's population pressures to its resulting economic growth, need for economic resources, and geopolitical efforts are examined using the concepts and holistic capabilities that are the academic strength of geography.     

洛阳市旅游资源的空间结构及其演化模式

通过对洛阳市旅游景点体系的集聚度、通达度和分异度指标分析,认为洛阳市旅游资源空间分布呈现整体均匀、中部集聚态势,景点网络的通达度有待提高。基于洛阳市旅游资源的密度和品位度空间分布等高线图,将洛阳市旅游资源化为3个核心-边缘单元:即洛阳——文化旅游资源体系、栾(川)嵩(县)——山岳旅游资源体系和新安——山水旅游资源体系。根据区域发展的离散阶段、成长阶段和成熟阶段,讨论了3个资源体系目前所处的阶段和边缘地区可能的发展趋势。     

罗布泊地区凝结水对潜卤水资源量评价的影响分析

新疆罗布泊地区属于极端干旱气候地区,大气降水对地下水的补给极其有限,长期以来,众多学者认为凝结水量是罗布泊干盐湖潜卤水的重要补给来源之一。本次通过在罗北凹地地区开展的凝结水试验,较准确地计算了其补给资源量,指出尽管研究区凝结水总生成量较大,但真正能入渗补给到潜卤水饱水带的量却极少,绝大多数凝结水都以难以开发利用的土壤水形式短暂保存,被蒸发散失到大气中,对潜卤水资源量评价影响较小。     

重庆市巴南区地热资源开发利用现状及前景分析

巴南区地热资源丰富,热储总存量为3.105×1015KJ,热流体储存总量为6.855×108m3。经30多年的开发利用,已初步形成了以东温泉、南温泉、桥口坝温泉为核心的温泉旅游开发格局,主要用于温泉房地产开发、风景区、温泉旅游、康乐疗养休闲、商务会展等。为提升开发利用水平,巴南区地热水资源开发要以市场为导向,以效益为目标,突出重点、打造精品、强化特色、完善配套,建设特色温泉产业。     

杭州苕溪滩涂湿地水质净化技术

苕溪位于杭州市余杭区,是区域内的一、二类饮用水源重要保护地,余杭区及杭州部分城区数百万居民的饮用水以及西溪湿地的水源都来自苕溪。阐明了苕溪水质污染原因,分析了利用湿地滩涂净化苕溪水质的可行性及方法。     

水源林区人工湿地污水处理技术的应用示范

针对水源林区的污水处理和循环利用等问题,设计了水平潜流人工湿地+垂直流人工湿地污水处理工艺,该工艺依靠重力作为动力,无需能耗,管理简单,污水处理效果较好,抗冲力负荷能力较强。运行结果表明,工艺出水主要指标达到了《地表水环境质量标准》(GB3838-2002)规定的I类水质标准。
