一种面向网络发布的海洋数据库引擎

To meet the requirements of efficient management and web publishing for marine remote sensing data, a spatial database engine, named MRSSDE, is designed independently. The logical model, physical model, and optimization method of MRSSDE are discussed in detail. Compared to the ArcSDE, which is the leading product of Spatial Database Engine, the MRSSDE proved to be more effective.     

国内地质灾害机理与防治技术研究现状

根据2013年4月10～12日在北京召开的第六届全国地质灾害与防治学术会议的特邀报告、主题报告以及论文集所报道的目前国内地质灾害机理与防治技术现状,分别从地质灾害成灾机理与减灾对策、地质灾害监测预警、地质灾害防治技术与应急处置、区域地质灾害风险管理与评价等4个方面进行简要介绍和分析。这些方面的研究成果代表了目前国内地质灾害机理与防治技术研究的现状和发展方向,对促进我国今后的地质灾害机理与防治技术研究有一定的积极作用。     

基于ArcGIS Server的GIS Web服务自动发布关键技术研究

Web GIS技术主要采用GIS Web服务方式对外提供资源访问和空间分析能力。GIS Web服务提高系统资源利用率,扩大信息使用范围,但GIS Web服务主要依赖于服务器端GIS平台提供的可视化工具进行后台发布,前台用户无法根据自己业务需要自动发布GIS Web服务。文中基于ArcGIS Server平台研究一种GIS Web服务自动发布方案,以双丰林业局林政资源服务系统的在线采编模块为例,阐述该案例的应用。     

Support for,and Impacts of Publishing in the Annals of the AAG: The Authors and and Editor Speak

A survey of 176 authors who published in the Annals between 1988 and 1993 provides insights into why authors submitted their research to the journal, what support they received, and the impacts of the publication on their careers. Most decided themselves to submit their work, and one-third received support from research grants; cartographic assistance and graduate assistants were less important. The major benefits of publishing in the Annals were visibility in one's department, contact with other geographers, and requests for reprints. Most authors presented their ideas at professional meetings prior to submission. Promotion and salary Inc.reases were benefits for women, assistant professors, associate professors, and physical geographers. Authors considered their articles as original examinations that yielded new results, contributed to theory, stimulated debate, and helped bridge gaps inside and outside of geography. These results are useful in helping individual authors and for administrators in identifying the kinds of research support needed by authors publishing in the Annals.

高校多媒体教程建设的思考——兼谈《地球科学》电子教材制作

结合高校电子教程的发展现状讨论了建设多媒体电子教程的必要性和可能性,并针对高等教育的特点提出了建设电子教程的目的及其应当具备的特点,最后以《地球科学》研制为例,介绍了教程研制过程中应当注意的几个关键环节和制作目标,强调了知识的整体感和表现形式的多样性。     

试论资源科学的发展与任务

归纳了资源的三类定义,回顾了资源概念中的时间尺度和价值理论问题,并对我国资源研究工作进行了总结,最后认为资源科学在２１世纪将会得到长足发展,为此需要开展１０个方面的研究工作,并应尽快使资源科学进入国家学科体系。     

Sharing academic space

This paper is a personal reflection on my participation in the panel “The Spaces of Critical Geography” at the ICGC in 2002, where my position as an European Americanist working in Asia was helpful in disrupting any tendency towards conflation of location, nationality, identity, and academic practice. These reflections focus on three topics: my interactions with various hegemonies and hierarchies; my relationship with the English language; and the contribution I believe critical geography can make to contemporary academic practice across the disciplines.     

GIS数据的出版可视化技术研究与实践

GIS空间数据的出版可视化技术研究与实践，不仅能够满足GIS空间数据的出版要求，同时对于最大限度地利用GIS数据资源、避免基础数据的重复投入和提高地图生产效率有着重要的现实意义。文章论述了地理空间数据的类型、关系、矢量数据结构及其在电子出版系统中共享的制约因素，讨论了GIS空间数据在电子出版系统中可视化技术实现的基本方法，在实践的基础上提出了两种企业级解决方案。
