基于GIS的矿区大气环境信息系统

Air environment information system based on GIS in the mining area

计算机软、硬件支持下的GIS系统因具有强大的空间数据处理、分析功能而被广泛应用于环境科学领域.以ArcViewGIS为主要软件开发平台及某一矿区为例,探讨了采用面向对象的脚本编程语言Avenue建立和开发基于ArcView的该矿区大气环境信息管理系统.该系统集查询、分析及预测于一体,不但能完成空间数据和属性数据的输入、输出、修改、查询、添加、统计分析等数据管理工作,而且能根据特定的字段绘制图形,具有浓度预测计算、生成等值线和等值区域图等空间分析功能.区域大气污染信息系统的建立将为区域大气环境的规划、管理、决策提供高效及科学的信息支持,从而提高管理水平.

Supported by computer software and hardware, GIS has powerful treatment and analysis function of spatial data. So, it is widely used in environmental fields. A certain mining area is taken as an example, the paper discusses the establishment and exploitation of air environment information system in the mining area by using programming language facing objects, the Avenue base on ArcView. The system can achieve the function of query, analysis and forecasting, which it can input, output, modify, query, append and analyze spatial data and attribute data. It can protract graph according to given fields, also, the system has the spatial pollution data analysis, which including concentration forecasting, creating figures of isolines and equivalent areas. The establishment of the air environment information system can increase managing level through supply efficient and scientific information support to regional air environment planning, management and decision.
