摘要
位于东南极Grove山地区的天然地质和独特地貌有助于解决许多重大的科学问题。为了保护该地区特殊的科学价值、美学价值和荒野价值,中国提出了建立南极Grove山自然保护区的设想,如何有效管理该地区的信息资源,为保护区的设立和管理提供决策支持成了一个急需解决的问题。本文介绍了南极自然保护区的研究现状,分析了南极Grove山自然保护信息系统数据特点,以及功能和性能需求,设计了双重模式(C/S模式和B/S模式)三层体系框架(数据层、应用层和表现层)的南极Grove山自然保护区信息系统,在此基础上,采用组件式GIS和Web GIS技术实现了原型系统,从而为Grove山空间数据和专题数据的有效管理,以及自然保护区的决策支持管理,提供了保护区信息交流与共享的平台。
In recent years, the Antarctic scientific expedition and research has become the focus of the world. Grove Mountains which locate in South Antarctic could help to resolve many important scientific problems because of their natural and unique geological landforms. Therefore, in order to protect particular scientific, aesthetic and wildness value in this area, our country has proposed to establish Antarctic Grove Mountains Nature Reserve. How to manage the information resource in this area, however, has become a serious problem. First, this paper analyzes the current situation of Grove Mountains Nature Reserve, such as the physical environment, research value and management activities and goals. Then, based on this situation, requirements analysis has been done frown data, function and performance aspect, and related GIS application technologies have been discussed. Furthermore, the overall design of this system is introduced. Dual mode （ C/S mode and B/S mode） and three-tier architecture （ data tier, application tier and presentation tier） are utilized to construct the system. The functions was divided into five parts： data input, operation, edit, output and distribution. Vector data, image data and thematic data have been imported and stored in GeoDatabase using ArcGIS toolbox. The vector data consists of rock, ice, water bodies, water courses, sub-glacial lakes, mountains, glaciers, ice shelfs, coast line, contour line, station, place name, geodetic control point, and the vector data. The large scale vector data can be downloaded from UK Antarctica DigitalDatabase （ADD）. The image data includes different observation phase TM and SPOT image. The thematic data includes coastline type, ice shelf, watercourse, human, continental Antarctica and management zones. The human layer includes building, tanks, wharves, landing area, refuges, and masts. The management zones include station limits, recreational limits, no go zones, and magnetic zones. The system shows that it is an effective approach for diverse Antarctica Grove Mountain＇s spatial related data and is useful for manager decision and data information sharing.
