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。
The remote sensing technology was used to investigate the ginseng planting area in the ginseng planting area, and a technical route method for the ginseng resource remote sensing survey was established. The ginseng area was measured and estimated by sample survey. Comparative analysis of field verification points and image interpretation results showed that the accuracy of manual interpretation of ginseng survey plots was 90% for Landsat 7ETM images (15 meters), 97% for ETM and Spot fusion images (5 meters), and Quick Brid images (0. 61 meters) reaches 100%. This study explores the application of remote sensing technology in the investigation of traditional Chinese medicine resources.
