摘要
目的以江西省余干县血吸虫病监测点螺情监测为例,评价全球定位系统和数字化地图和影像的实用性与优越性,为利用地理信息系统管理和表达全国血吸虫病监测点数据提供理论支持。方法收集江西省余干县血吸虫病监测点20个查螺洲滩的地理信息、螺情资料,通过数字化地图对此地区的卫星图片进行校正和提取,对余干县螺情的现状和趋势进行综合分析和表达,并介绍建立监测系统中涉及的设计思想和技术细节。结果通过对20个洲滩建立的数据分析表达流程图,验证了余干县监测数据库地理分析平台的有效性和实用性。结论全国血吸虫病监测数据完全可以通过全球定位系统与地理信息系统连接,能对监测数据进行正确表达和安全管理,为有效地利用监测数据提供了一个科学的平台。
Objective To use the snail survey data of Yugan, Jiangxi Province as an example to evaluate the effects and advantages of global positioning system integrated with digital maps and remote sensing data in order to manage and analyze the whole country＇s surveillance data of schistosomiasis by using geographic information system. Methods The data of geographic information and snail information of 20 marshlands in Yugan, Jiangxi Province were collected, and by the correction of remote sensing images based on the digital maps and index extraction, the snail current situation and trend were analyzed and expressed. Results A series of specific procedure images of these 20 marshlands was established and the effects of Yugan surveillance platform based on geographic information system were validated. Conclusion The whole country＇s surveillance data of schistosomiasis might be successfully integrated with geographic information system by global positioning system and be managed and expressed, which supplies a successful platform in using the surveillance data effectively.
