地质环境特征及工程适应性与选择性分析——青岛市城市地质环境研究

根据地形地貌、地质构造、水文地质条件将青岛市划分为６个工程地质亚区，论述了各亚区地质环境特征，结合不同城市建筑工程特点，进行了工程场地适应性和选择性分析评价，为充分合理利用城市地质环境提供良好依据     

Early holocene high magnitude debris flow events and environmental change as illustrated by the Moxi Platform, Hengduan Mountains, SW China

Introduction Landscape evolution in glaciated high mountains environment in southwestern China is undergoing the coupled processes of monsoon- induced denudation and active tectonic. The debris fan development, in particular sediment transfer, is most int…

陕蒙交界地区碎屑岩风化成因浅析

陕蒙交界地区基岩均具强风化,由此造成当地环境恶化、下游地区生态破坏和灾害积累。其形成机理应与岩石本身的物质组成、自然地理环境、地质构造状况、水文地质条件及其物理化学条件有关。而南部地区,由于上述诸因素的差别,基岩风化微弱。     

Measuring Urban Streetscapes for Livability: A Review of Approaches

Increasing interest in urban livability demands that geographers and planners more precisely define what constitutes a livable streetscape, a fundamental building block of urban places. Widespread examination of streetscape livability will require precise and efficient measurements of (1) physical characteristics at the spatial scale of individual streetscapes and (2) indicators of experiential quality based on revealed behavior or stated preference. This article reviews approaches to collecting both types of measurements, showing that innovative methods using geographic information systems (GIS), Internet-enabled surveys, and even social media could be useful complements to traditional qualitative methods for collecting streetscape measurements.     

"数字地球"与资源环境的可持续发展

介绍了“数字地球”的概念及应用范畴,论述了资源环境可持续发展的战略意义,分析了数字地球信息在资源调查、环境条件等可持续发展核心问题中的应用。提出“数字地球”与资源环境可持续发展二者相互促进、共同发展,“数字地球”是实现资源环境可持纽发展的重要手段,而社会经济的发展又为构筑“数字地球”提供必要保障。     

浅谈海绵城市建设与城市水文地质勘查工作

海绵城市是构建"尊重自然、顺序自然、保护自然"建设生态城市的新型理念。目的是实现低影响开发雨水控制与利用,雨水资源化管理,减轻城市内涝,达到水生态与城市发展平衡的可持续发展建设模式。本文主要提出了城市水文地质勘查在城市海绵建设中的必要性,及城市水文地质勘查如何开展和服务于海绵城市建设。     

关于火山岩型铀矿床成矿规律中一些问题的讨论

火山岩型铀矿常位于大的地质构造单元界线附近,特别是稳定区与活动区之间的过渡带上。矿区的基底不仅需有较高的成熟度而且是在火山岩形成前或长期处于隆起状态者。负向火山构造,上叠式或拗凸型上叠式火盆是铀矿田的有利构造形式。红盆对成矿的作用不是古气候方面的而是构造方面的。火山岩型铀矿成矿深度可以较大,而且在垂向上不只一个富集高峰。铀及其主要伴生组份不是来源于赋矿围岩,而是来自基底或更深处。     

九龙江河口区现代沉积环境及其物质输运趋势

对九龙江河口区58个表层沉积物样品进行了激光粒度分析,并分别应用系统聚类分析和GSTA模型分析,探讨了研究区的沉积特征、沉积环境和表层沉积物输运趋势。结果表明,九龙江河口区表层沉积物由10种沉积物类型组成,与20世纪80年代相比,该海区底质沉积物在类型分布和粒径粗细上发生了一定的变化;将研究区划分为3种与沉积动力特征相对应的主要沉积环境区;表层沉积物输运趋势因受该区特殊的地形和复杂的水动力条件影响而表现为北进南出,海门岛西北海域形成逆时针方向输运趋势,而海门岛以东海域形成三向汇聚的输运趋势。     

Media Institute on Geographic Concepts

Abstract

A new political geography has emerged that stresses the political conflict behind the production of space. This orientation in the subdiscipline constitutes a turn away from traditional political geography, where the emphasis had previously been on the spatial distribution of political phenomena. The “new” political geographic theory has been applied to the study of environmental issues, turning the attention of scholars to the political struggle behind the construction of nature as well as space. This article reviews how the new political geography of the environment (NPGE) perspective has impacted the study of such environmental phenomena as hazards, siting issues, human-land relationships, resources, development, and international environmental governance. It concludes by suggesting how the NPGE perspective can inform pedagogy in environmental education.
