云南玉溪抗旱找水定井典型实例分析

西南大旱百年不遇,山东找水专家组紧急驰援云南抗旱。通过对云南抗旱找水成功定井实例的分析,总结了高原岩溶水和"红层"基岩裂隙水的找水勘察工作,并联系云南、四川、山东等贫水区找水定井实践,阐述了贫水区找水定井思路与方法。     

Geospatial preparedness: Empirical study of the joint effort to provide geospatial support to disaster response

In a disaster aftermath in places lacking geospatial preparedness, the United Nations Office for the Coordination of Humanitarian Affairs creates a framework for cooperation with the Coordinated Data Scramble initiative, where Information Management Officers (IMOs) from different organizations work together in supporting the coordination of humanitarian aid. The perspective of these IMOs has been considered to identify the factors influencing the use of GIS in this context. The results show the requirement for a geodata management strategy, including geodata gathering, maintenance, and decision‐making processes based on those geodata. Geodata should be reliable and up‐to‐date. It requires consistent and useful metadata and the possibility of contacting the geodata source. Security and political issues limit information sharing. In this context, OpenStreetMap is often used as a source of information. Therefore, improving OpenStreetMap improves geospatial preparedness. Nevertheless, the use of this open platform highlights issues related to information privacy.     

基于Skyline和IDL平台的地质数据三维可视化研究

地上地下信息三维可视化在地质勘探中具有重要作用。首先研究了地质数据建模的主要方法;在分析和比较当前主要三维可视化平台的基础上,基于Skyline和IDL开发平台进行了详细的系统设计;最后,开发和实现了集地上地形地貌信息和地下地质数据的三维可视化分析系统。结果表明,文中的设计方案能够很好地集成地质勘探中的地上地下信息,实现三维可视化分析。

地热形成条件探索与找热方法研究

储、盖、通、源是对地热形成条件的简述。通过多年的地热勘查工作实践,笔者认为：储、盖、通、源仅仅是地热形成的必要条件,深部“承压水滞留”才是地热形成的充分条件。“储、盖、通、源、滞”是地热形成的“充要”条件。
