ISO 9000质量管理体系在地理国情普查工作中的应用

开展地理国情普查,是党中央、国务院对测绘地理信息工作服务国家宏观管理、规划决策提出的新的更高的要求,也是新时期测绘与地理信息部门服务经济社会科学发展新的实践和重大任务,做好这项工作具有重大的现实意义和历史意义。 ISO 9000质量管理体系吸收国际上先进的质量管理理念,对于产品和服务的供需双方具有很强的实践性和指导性,因此将ISO 9000质量管理体系应用于地理国情普查工作中,可以使生产单位更高效、快速、准确地完成工作,提供普查成果。     

网络计划管理技术在长江某穿越隧道工程中的应用

网络计划技术是一种科学的计划管理技术，它对工程组织过程和项目实施步骤进行全面的规划、编排，并在工程项目实施初期对多种方案进入深入的研究与比较，更科学地进行目标进度的安排。本文以长江某穿越隧道工程为例，详细探讨了用网络计划技术进行工程管理的过程。     

省级气象云资源管理平台设计与应用

基于OpenStack架构建立省级云资源管理平台,通过整合省级各类硬件资源,将计算、存储、网络等硬件资源纳入统一资源池管理,在此基础上将省级原有的多套虚拟化系统软硬件资源纳入平台统一管理。平台投入使用后资源有效利用率大幅提升,实现硬件资源动态、弹性、可回收利用,能够更好地为各业务部门提供硬件资源服务。通过接管省级VMware、OS等虚拟化系统,平台可以根据业务需求快速部署交付业务系统,大幅提高对气象业务的服务和支撑能力,提高了系统运维的水平和效率。该平台的建成和应用对省级云计算发展和应用具有示范、服务、探索等多重作用,特别是对带动省级信息化建设进入新阶段,探寻省级新的信息化建设模式具有现实意义。     

Landslide susceptibility and hazard mapping in Australia for land-use planning — with reference to challenges in metropolitan suburbia

This paper provides an overview of the history and current status of landslide susceptibility and hazard mapping for land-use zoning in Australia. It also describes a case study of landslide hazard mapping in a medium density, coastal, suburban residential area of metropolitan Sydney, New South Wales, Australia, with relatively steep terrain. Issues covered include identification and mapping of existing and potential landslides, and susceptibility and hazard zoning for regulatory management and land-use planning. The method involves application of the principles contained within the AGS (2000) guideline, and as updated by the AGS (2007 a,b,c,d,e) suite of guidelines.     

Improving marine environmental health through marine citizenship: A call for debate

This paper presents an evaluation of the role of marine citizenship in improving marine environmental health and marine governance. Marine citizenship describes the rights and responsibilities of an individual towards the marine environment, which support the achievement of marine policy objectives at the national level. It is argued that marine citizenship requires an enhanced awareness of marine environmental issues, an understanding of the role of personal behaviour in creating and resolving marine environmental issues, and a shift in values to promote marine pro-environmental behavioural choices. It is concluded that the value shift is likely to be produced by the development of an altered relationship between the state and the individual, in which the expectations placed on citizens by the state are extended to include marine pro-environmental behaviour. The paper is intended to stimulate debate and the authors invite and encourage replies to the ideas contained within the paper.     

Large scale failure of the external waste dump at the “South Field” lignite mine, Northern Greece

This paper presents the failure process of the external waste dump of the South Field Mine, the major open pit mine in Greece. The waste materials of the mine were deposited in three phases, forming an average inclination slope 10% and a total height of 110 m from the ground surface. The failure occurred when the third phase of the deposit was initiated. The high moisture content of the waste materials and their deposition over a spring, choking its flow, had as a result the development of high pore water pressure in clayey and marly materials in the base of the deposit. As a consequence, a large scale slope failure incident occurred. The landslide involved the mobilization of waste material in the order of 40 Mm³, while the material that moved outside the boundaries of the waste dump was in the order of 2.5 Mm³. The stability of the waste dump was investigated using the limit equilibrium analysis and different types of models.Limit equilibrium analyses were performed using different methods and considering the clay layer of small shear resistance that exists in the base of the deposit. They do not indicate activation of failure mechanism, only that there is a combination of high pore water pressure that developed in the deposit because the covering of the spring with the clayey materials of the dump.     

肥城市采煤塌陷区治理模式探索研究

肥城煤田作为国家重要能源基地,开发历史悠久,为我国高速发展的国民经济做出了巨大贡献。但长期开采导致塌陷范围广、深度大、积水严重,生态环境遭受严重破坏,给矿区群众的生产生活带来严重影响。该文总结了目前普及化程度较高的采煤塌陷区治理模式,以此为基础,对肥城市采煤塌陷区按照因地制宜的原则,通过分析研究、归纳得出适应于肥城市采煤塌陷区四种不同的治理模式,分别为:土地复垦治理模式、“渔业+农业”治理模式、生态修复治理模式、综合治理模式,并对四种治理模式进行了阐述分析,对今后肥城市采煤塌陷区治理起到借鉴和指导作用。     

大数据架构的遥感资源存储管理方法

随着遥感数据获取能力的日益增强,一方面导致遥感数据的多元化和海量化,使“存不起”的问题日益突出,另一方面由于缺少有效和高效的存储管理方法,难以及时发现终端应用所需的数据,使结果“存而无用”。本文围绕巨量、高吞吐、空间结构化的遥感影像数据及其基础土地信息产品的存储与管理问题,提出采用大数据架构的遥感资源存储管理方法,并基于MongoDB数据库实现了原型系统;通过使用PB量级数据进行试验,证明了该方法满足大数据时代对遥感矢栅数据的存储管理需求。
