目的:探讨区域范围中药资源普查中3S技术的运用模式,为第四次全国中药资源普查的全面展开提供技术应用层面的参考。方法:借助GPS定位仪、单反相机等硬件设备和Google Earth、HOLUX ez Tour for Logger、XTTools等处理软件,在区域中药资源普遍调查实施中实现遥感技术、全球定位技术、地理信息技术的运用,选择适合区域资源普遍调查的3S技术应用模式。结果:通过实地调查总结出的3S技术运用模式可在区域中药资源普查过程中有效完成样地、样线调查任务,实现地理信息采集并将其与调查物种一一对应,以及后期数据的统计分析。结论:3S技术在区域中药资源普查中的运用,可提高普遍调查的效率,且能获取更为准确的资源地理信息,有利于中药资源信息的共享和动态监测。
OBJECTIVE: To explore the mode of application of 3S technology in the regional census of Chinese medicine resources and to provide a reference for the technical application of the fourth national census of Chinese medicine resources. Methods: With the help of hardware such as GPS locator, SLR camera and processing software such as Google Earth, HOLUX ez Tour for Logger and XTTools, the application of remote sensing technology, global positioning technology and geographic information technology 3S technology application mode suitable for general survey of regional resources. Results: The 3S technology utilization model summarized in the field survey can effectively complete the sample plots and sample line surveys in the process of census of traditional Chinese medicine resources in the region, and achieve the geographic information collection and its correspondence with the surveyed species, as well as the statistical analysis of the later data . Conclusion: The application of 3S technology in the survey of Chinese medicine resources in the region can improve the efficiency of universal investigation and obtain more accurate geographic information of resources, which is beneficial to the sharing and dynamic monitoring of traditional Chinese medicine resources.
