摘要
采用EC-386微型电子计算机,以Auto CAD图形软件包,建立农业土壤污染数据信息图形化处理系统。该系统不仅有查询、计算等功能,而且还具有绘制和显示样点分布图、等级线图、污染级别频率分布条形图、制作和显示幻灯片等功能。所绘制的各种图形还可以通过绘图仪输出。从而使各污染元素在各检测点的地理位置和污染程度清晰地显示在地图上。该系统具有操作简便、灵活、通用性和实用性强等特点,符合环保数据信息图形化处理的要求。
This paper details a method of creating data base management system with graphic programming by Auto CAD software package in agricultural soil pollution on EC-386 microcomputer. The system not only can perform general search, data and statistics calculation but also can draft and display distributed graph, line graph of equivalent value and bar of frequency distribution, or make and display slides. The various graphs are output with plotter. The system is convenient for monitor in agricultural soil pollution.
