摘要：渭源县作为党参的主要种植地区,所产的党参质优量大,是中医较为推崇的中药之一,但其耕地区域地势险峻、沟壑较多,渭源县中药材产业办公室每年都耗用大量的人力、财力、物力对其面积进行估算也不能得到较为准确地种植面积信息,为了更快速简捷的提取当地党参种植信息,尝试将已经较为成熟的遥感技术应用于党参种植面积信息提取中。该文将以甘肃省渭源县为研究区域,以国产资源三号(ZY-3)所获得的多光谱遥感影像作为数据源,通过对比找出以党参的植株形态为线索与其他地物在遥感影像中的光谱特征差异,利用目视解译法来提取计算渭源县党参的种植面积。利用卫星遥感技术对党参种植面积的估算值为75 965亩(1亩≈667 m^2),与渭源县中药材产业办公室实地调查数据基本相符,精度验证后发现利用目视解译法提取的党参种植地精准度在70%以上,能够准确反映所需信息。说明卫星遥感技术可用于党参种植信息的提取,可以快速准确提供相应中药材种植面积的相关信息。
Due to the large amount of Codonopsis pilosula planted in Weiyuan county,and the arable land area,the local medicinal materials office uses a large amount of manpower,financial resources and material resources to estimate its area every year.In order to extract the information of local Chinese medicinal materials more quickly and simply,we try to apply remote sensing technology to the extraction of Chinese medicinal materials.This paper will use Weiyuan county of Gansu province as the research area,and use the domestic ZY-3 Satellite multi-spectral remote sensing image as the data source to find out the spectral characteristics of the party’s participation in other remote sensing images.The visual interpretation method was used to extract the planting area of the C.pilosula in Weiyuan county.The estimated value of the planting area of C.pilosula using satellite remote sensing technology was 75 965 mu(1 mu≈667 m^2),which was basically consistent with the field survey data of the local medicinal materials office.After the accuracy verification,it was found that the precision of C.pilosula planted by visual interpretation was more than 70%.It is concluded that the satellite remote sensing technology can be used to extract the information of C.pilosula and it can provide the relevant information of the planting area of Chinese medicinal materials quickly and accurately.
