摘要
系统介绍了研制城市空气质量监测系统时所面临的主要问题及解决方法．首先讨论了基础空间数据及属性数据结构；录入了大量空间数据，并用开放数据库互连（ＯＤＢＣ）技术实现了与环保部门已有数据库的连接，从而解决了大量属性数据的录入问题；在此基础上，实现了普通的信息查询和地理信息系统所特有的图示查询及现有的各种空气质量评价功能，并进一步提出了基于ＧＩＳ的空气质量评价新方法．
This paper discusses the principle and mainpoint of air environment quality monitoring system which uses the geographic information system method. First, it discusses the structure of spacial data and attribute data of the system. Then the spacial data are inputted and the open database connectivity technique is used successfully to solve the problem in the input of a large amount of attribute data. On this basis, both the traditional query of information and graphical query are realized. Then a new method is developed to evaluate the air environment quality, which is better than the old ones.
