利用遥感技术对人参种植区域的人参种植面积进行调查,建立了人参资源遥感调查的技术路线弄口方法,并通过抽样调查对人参进行了产区面积测算和估产。野外验证点与图象判读结果对比分析表明,人参调查样区的人工判读精度,Landsat7ETM图像（15米）达90％,ETM与Spot融合图像（5米）达97％,Quick Brid图像（0．61米）达100％,本研究为遥感技术在中药资源调查中的应用摸索了方法。

This article describes the investigation of the cultivated areas of ginseng in the regions of its cultivation by remote -sensing technology, the establishment of technical routes and methods for the investigation of ginseng resources by remote - sensing and the calculation of the cultivated areas and the estimate of the yields of ginseng via sample survey. The compararison of the results from field verification points and image interpretation shows that in the sample areas of ginseng investigation the precision of artificial interpretation of landsat 7ETM image （15m） is 90% , that of the integrated image （5m） of ETM and spot reaches 97% and that of the Quick Brid image （0. 61m） is as high as 100%. This study has probed into the method for the application of remote - sensing technology to the investigation of the resources of Chinese medicine.
