本文在我国大规模开展地震测深工作的基础上,提出了地震测深数据文件系统,其目的在于在测深资料解释中引进数字处理技术,增加地震记录可用的信息量,建立地震测深数据库,从而促进我国深部研究工作中资料的相互交流. 在IBM-PC/XT微型计算机上,与本文的数据文件系统相应的数据采集、文件组织、绘制地震记录截面图以及对数字记录进行预处理等方面软件设计已经完成,从而建立了较完善的地震测深数据处理软件包.这个软件包在野外的使用表明,它具有效率高、使用方便的优点. 相似文献

Embedding a Geographic Information System in a Decision Support System for Landslide Hazard Monitoring 总被引：2，自引：0，他引：2
In this paper we present an application that exploitsa geographic information system as a front-end of acomplex information system supporting the managementof landslide hazard in Valtellina, an alpine valley inNorthern Italy.A decision support system (EYDENET, operational sinceOctober 1996), incorporating a geographic informationsystem and a data interpreter based on artificialintelligence techniques, processes the readings of the250 most significant instruments of a monitoring netof about 1000 sensors installed on differentlandslides in several alpine valleys.Data gathered by extensometers, clinometers andpluviometers, to check both movements of rocks andclimatic conditions which could affect them, areprocessed by EYDENET, that provides on-lineinterpretation of data, helps the users analyse them,and generates natural language explanations and alarmmessages for the people responsible for theenvironmental management and the civil protection. 相似文献

Mine contamination is one of the main obstacles to economic recovery and other types of progress in mine‐affected countries. Therefore, the primary goal of humanitarian demining operations is to clear all suspected minefields and restore them so as to make them available for their previous use. The customary financial shortfall results in the need for priority setting in the mine removal process. This paper describes and investigates a new approach to priority setting within mine action, with the introduction of a hierarchic GIS‐based decision support system (DSS). The proposed DSS is aimed at determining the objective priorities required to reduce the risks stemming from mine contamination. DSS is based on a combination of GIS analysis and a multicriteria method in order to enable efficacious mine action management, namely setting humanitarian demining priorities in order to optimally reduce the risk caused by mines. GIS is outlined as a powerful tool for the generation of aggregated information used in multicriteria analysis, as is the link between hierarchic decision levels in the proposed DSS. The results of a demonstration of the proposed GIS‐based DSS on mine‐affected water resources in Croatia are supplied. 相似文献

残余壳根与"三明治"结构——燕山造山带中段地壳结构的主要特征 总被引：2，自引：0，他引：2
摘要昌黎一承德一达莱诺尔宽角反射／折射地震剖面完成于1985年,呈NW向横过燕山造山带中段,部分测段与2002年实施的120km深反射地震剖面重合。为获得区域深部构造背景并在与反射地震剖面交互解释基础上,对该剖面的4炮原始资料进行了处理、解释,获得了一个厚35-38km,局部残余壳根,夹有低速层的“三明治”式的地壳结构模型。该结构样式明显不同于板缘俯冲／碰撞造山带常见的楔入（挤入）样式,也区别于澳大利亚Alice Spring造山带的厚皮变形样式,在世界陆内造山带中独具特色。燕山造山带的地壳结构模型暗示该区保持着中生代区域收缩变形形成的地壳结构基本格架,下地壳和Moho的特征显示了后期区域性伸展作用的影响。 相似文献

针对榆林地区水资源相对贫乏,煤炭资源不合理的开采对地下水资源造成巨大破坏,严重威胁着该地区的可持续发展的问题,应用系统工程方法,将水资源放在社会、经济、资源、生态、环境所组成的复合系统中进行整体研究,构建地下地下水资源-生态环境-社会经济系统模型,可以为水资源的优化配置、开发利用规划、管理决策、落实最严格的水资源管理制度提供技术支撑。分析结果表明榆林地区在水资源、环境和经济目前处于不协调阶段,经济发展较快,但水资源相对贫乏,经济的发展对环境造成很大有破环并且对于环境的治理和保护投入的资金较少,采矿区水资源污染较为严重。 相似文献
