基于VisualDB珠三角POPs数据库构建及应用

VisualDB-Based POPs Database of Pearl River Delta Area Construction and Application

珠江三角洲是我国和世界上持久性有机污染物(Persistent Organic Pollutants,POPs)研究程度最高、数据积累最丰富的地区之一。通过数据库技术、可视化技术和网络技术,建立了珠江三角洲POPs数据库系统,并利用中科院计算机网络信息中心科学数据中心开发的可视化工具VisualDB对数据库进行了发布。利用本系统对珠江三角洲POPs进行了分析和讨论,实现了本系统的初步应用。结果表明珠江三角洲地区环境中的土壤、大气、水体和生物体等各种介质中均不同程度存在着POPs污染,并发现了部分POPs污染物的分布与演化规律,说明了本系统具有很好的应用前景。

The pearl river delta is one of the areas for the study and data accumulation of Persistent Organic Pollutants（POPs） in the world.Built a POPs database in this area by using the technologies of database,visualization and networks.The database was published in web through a visualization tool,VisualDB,developed by the computer network center of chinese academy of sciences.Finally,the characteristics of POPs in pearl river delta area was analyzed and discussed as a preliminary application of the database system.It was suggested that POPs in pearl river delta area existed more or less in the soil,air,water,organism and so on.The distributing and evolving rule of POPs in this area was discovered.It indicated that the application of this system would be extended well.
