摘要：由于在当归种植过程中需要大量营养并且为了预防病虫害的发生,同时为了防止当归的种植面积的逐年减少和药材市场当归的供需平衡,当归种植地采用轮作模式。为了能够对当归种植面积进行有效的宏观调控,获得准确地理分布信息。该文以甘肃省渭源县为研究范围,以高分一号(GF-1)卫星数据作为数据源,应用遥感技术再结合实地调查结果,探索目视解译法对当归种植面积提取的有效方法。根据不同地物类型选取样本生成光谱图。分析得到当归与其他地物的不同特征并在遥感影像中加以区分,从而在遥感影像中对当归种植地块进行提取并且进行精度验证。结果显示,目视解译方法精度验证值为95. 85%,确定了目视解译的方法能有效地提取出研究范围内的当归种植地块,实现了当归空间分布信息的全面掌握。
Due to the large amount of nutrients required during the cultivation of Angelica sinensis and in order to prevent the occurrence of pests and diseases,and the annual reduction of the planting area of Angelica and the balance of supply and demand of A.sinensis,the A.sinensis plantation adopts the rotation mode.This paper takes Wuyuan county of Gansu province as the research scope and use GF-1 Satellite data as the data source,using remote sensing technology combined with field survey results,to explore the effective method of visual interpretation for the extraction of A.sinensis planting area.A sample was selected to generate a spectrum according to different feature types.The different characteristics of A.sinensis and other features were analyzed and distinguished in remote sensing images,so that the A.sinensis planting plots were extracted and verified in remote sensing images.The results showed that the accuracy verification value of the visual interpretation method was 95.85%.It is determined that the visual interpretation method can effectively extract the A.sinensis planting plots within the research scope and realize the comprehensive grasp of the spatial distribution information of A.sinensis.
