摘要
目的利用地理信息系统技术确定伤寒Vi疫苗现场研究的试验组和对照组 ,建立地理信息分析系统。方法依据医学人口普查数据、疾病监测系统信息数据、现场采集的居民居住点全球卫星定位数据 ,在Foxpro6.0和ArcGIS8.2软件支持下建立实用的地理信息系统。结果建立了地理信息分析系统 ,研究获得基础数字地图、GPS居民点分布图、疾病分布图、组群分布图。结论建立数据详细、信息量大的GIS数据库对于准确确定研究组群、信息开发利用、疾病的防治和卫生决策均可提供技术先进、分析科学、定位准确的服务。
Objective Using geographic information system(GIS)technology to define the vaccine cluster and control cluster of typhoid Vi vaccine trial,and establishing GIS analysis system.Methods Medical census data,disease surveillance data and resident global position system data were collected,and relevant GIS databases were set up by using Foxpro6.0and ArcGIS8.2softˉware.Results GIS databases were established and local digital basic map,resident GPS point map,disease spatial distribution map and cluster spatial map were obtained.Conclusion Establishing a GIS databases contained detail and large information can provide advanced technique,scientific analysis and accurate position for cluster definition,exploitation and use of information,disease prevention and control and health policy decision.
