Abstract:

Objective To explore the drawing method of a statistical map based on statistics analysis system(SAS)and its application in the surveillance of exotic medical vectors and risk analysis in entry-exit inspection and quarantine system. Methods The statistical map method based on SAS program was applied for the classification statistics and data analysis of exotic medical vectors, with real-time, dynamic and automatic marking on the world map actualized. Results A world map was automatically drawn by computer and the related data and messages were labelled real-timely, dynamically and automatically on the world map in different colours. The locations of the twenty countries covered in this study were marked as asterisk in the map based on the longitude and latitude degree values of the capitals in those countries. Blue, yellow, orange and red colours were used to represent the different numerical levels of captured medical vectors. The numbers of vectors from Panama, Brazil and Thailand were marked by a blue asterisk indicating a relatively small number, while those from Korea South and South Africa were marked by red asterisk indicating a relatively large number. Conclusion The statistical map gives an intuitive, simple and dynamic illustration of the distribution of exotic medical vectors from different countries, contributing to inspection and quarantine authorities making timely, accurate and reasonable distribution of forces and strengthening quarantine supervision of what is imported from the countries as sources of relatively large number of exotic medical vectors.

摘要：

目的 探索基于SAS的统计地图绘制方法,及其在出入境检验检疫系统卫生检疫外来媒介生物监测工作中的应用。方法 应用统计地图法并采用国际权威的统计分析标准软件SAS分析平台进行编程,实现外来媒介生物截获信息的分类统计、数据分析,以及在世界地图上的实时、动态、全自动标注。结果 计算机自动绘制世界地图,根据20个国家首都的经纬度数据在图中用星号(★)标注出相应的国家位置,并用蓝、黄、橙、红4种颜色分别代表截获的媒介生物数量等级。来自巴拿马、巴西、泰国等国家的外来媒介生物量均以蓝星标注,表明截获量相对较少;来自韩国、南非等国家的外来媒介生物量均以红星标注,提示来自这些国家的外来医学媒介生物截获量相对较多。结论 统计地图可以直观、简便、动态地呈现外来媒介生物截获量在不同国家的分布情况,有助于检验检疫部门及时、准确、合理地分配力量,重点加强媒介截获量较大的来源国卫生检疫监管工作。
