基于GIS的陕西省地质灾害信息系统设计

Design of Geologic Hazard Information Systemin Shaanxi Based on GIS

GIS技术在灾害研究中的应用日益广泛,GIS强大的空间分析功能和海量数据管理优势为地质灾害数据的管理分析、动态监测、机理模拟、预测预报、辅助决策提供了强有力的支持。本文从陕西地质灾害分析入手,设计了基于GIS的地质灾害信息系统,并对系统目标、系统总体设计、系统功能进行了分析。该系统可为陕西省地质灾害的管理和防治提供科学依据,减少经济损失。

<Abstrcat>The Geographic Information System (GIS) technology has been widely applied in the study of hazard. GIS has a powerful advantage in spatial data analysis and management, which can provide powerful support in the geological hazard dynamic monitoring, mechanism simulating, forecast and management decision-making. Starting with the analysis of basic situation of the geological hazard in Shaanxi, the geologic hazard information system, based on GIS, is designed, and the objectives, overall design and functions of the system are analyzed. The system can provide scientific basis for geological disaster control and management and for economic loss reduction in Shaanxi province.
