3S技术在药用植物资源调查研究中的应用

3S技术在药用植物适宜性评价中应用较多,但在资源调查和储量估算方面研究较少,只集中在大面积栽培品种或野生广布种如人参、甘草、红花等少数几种药用植物,特别是在野生稀有药用植物资源调查方面的应用尚属空白。简述了中药资源普查的现状及近几年3S技术在栽培品种、野生广布种、野生稀有种、特殊生态环境药用植物资源调查及储量估算研究中的应用,并对高光谱遥感在中药资源调查及储量估算进行案例介绍。随着我国高分辨卫星的发射以及高光谱遥感技术的发展,使得利用3S技术对野生稀有种药用植物资源调查成为可能。

Application of 3S technology in resources survey of medicinal plants

The authors introduced the current situation of resources survey in Chinese materia medica (CMM) and 3S technology applied in the investigation of medicinal plant resources, summarized the applications in cultivars, wild widespread species, rare species of wild special ecological medicinal plant resources, and reserves estimation research by 3S technology in recent years. Presenting the hyperspectral remote sensing in CMM resources survey and reserves estimates for a case. More about the 3S technology was in medicinal plant suitability assessment application, but fewer were studies in terms of resource survey and estimating reserves. Most are concentrated in a large area of cultivated or wild species widely distributed species such as ginseng, licorice, saffron, and a few of several medicinal plants. Especially the application of rare species of wild medicinal plant resources investigation is still blank. With the launch of high-resolution satellite and development of hyperspectral remote sensing technology, making use of 3S technology on rare species of wild medicinal plant resources investigating is possible.
