【摘要】：中藥多種植在自然環(huán)境條件適宜而地形復(fù)雜的山區(qū),種植地塊分布零散,傳統(tǒng)調(diào)查方法很難獲得準(zhǔn)確的種植面積。通過(guò)研究基于遙感的中藥材種植面積提取方法,為中藥資源保護(hù)和利用提供決策支持有著至關(guān)重要的意義。該文以安徽省寧國(guó)市前胡種植為例,分別以30 m分辨率的Landsat-8和16 m分辨率的國(guó)產(chǎn)"高分一號(hào)"(GF-1)多光譜遙感影像為數(shù)據(jù)源,首先利用前胡在不同時(shí)相的影像光譜特征變化來(lái)提取寧國(guó)市耕地中的前胡種植區(qū)域,其次利用與前胡套種的山核桃幼林的紋理和光譜特征來(lái)提取寧國(guó)市林地中的前胡種植區(qū)域。結(jié)果表明:利用30 m和16 m空間分辨率影像提取的前胡種植面積分別為25 635.43,24 585.43畝(1畝≈667 m2)。與統(tǒng)計(jì)數(shù)據(jù)相比,16 m分辨率影像提取的結(jié)果精度較高。
[Abstract]:The traditional Chinese medicine is planted in the mountainous area where the natural environment is suitable and the topography is complex, the planting area is scattered, and the traditional investigation method is difficult to obtain the accurate planting area. It is of great significance to provide decision support for the protection and utilization of traditional Chinese medicine resources by studying the extraction method of planting area based on remote sensing. This paper takes Qianhu planting in Ningguo City, Anhui Province as an example, taking 30m resolution Landsat-8 and 16m resolution GF-1 multi-spectral remote sensing image as data source, respectively. Firstly, the paper uses the spectral characteristics of the image of Qianhu in different phases to extract the planting area of Qianhu in cultivated land of Ningguo city, and then extracts the planting area of Qianhu in the woodland of Ningguo by using the texture and spectral features of the young walnut forest interplanted with Qianghu. The results showed that the planting area of Bupleurum was 25 635.433m 24 585.43 mu (1 mu 鈮，
