【摘要】：川西獐牙菜是一種珍稀的中藏藥材,目前對于川西獐牙菜的研究主要集中在藥用療效和藥用價值方面,而基于遙感與GIS適宜性分布研究較少。運用遙感和GIS技術(shù)來研究分析四川省川西獐牙菜適宜性分布區(qū)域,為野生資源保護開發(fā)、人工引種栽培以及調(diào)整四川省中藥產(chǎn)業(yè)布局提供了科學依據(jù)。該研究在文獻查閱和分析川西獐牙菜分布適宜性的海拔、年降水、年均溫等生態(tài)因子基礎上,基于遙感與GIS技術(shù),獲取生態(tài)因子、疊加分析、結(jié)合GPS野外驗證數(shù)據(jù),對四川省川西獐牙菜的適宜性分布區(qū)域進行了研究。(1)川西獐牙菜在四川省適宜分布面積為1 543.749 km2,主要分布在德格縣、甘孜縣、道孚縣、康定縣、馬爾康市、金川縣、小金縣、丹巴縣、稻城縣、鄉(xiāng)城縣、新龍縣、阿壩縣、木里縣等縣市,占該區(qū)縣市總面積的7.25%;(2)相關(guān)資料以及野外實地驗證調(diào)查發(fā)現(xiàn),通過GIS得到的川西獐牙菜適宜分布區(qū)域與實際分布情況基本吻合。研究表明基于遙感與GIS技術(shù)提取川西獐牙菜適宜分布區(qū)是可行的,可以應用到其他道地珍稀中藥材的適宜性分布區(qū)域研究。
[Abstract]:Swertia Swertia is a rare medicinal material in China. At present, the research on Swertia mustii is mainly focused on its medicinal efficacy and value. Based on remote sensing and GIS suitability distribution, remote sensing and GIS techniques were used to study and analyze the suitable distribution area of Swertia mussii in Sichuan Province, which was used to protect and develop wild resources. Artificial introduction and cultivation as well as adjusting the layout of traditional Chinese medicine industry in Sichuan province provide scientific basis. This study is based on remote sensing and GIS technology, based on the analysis of ecological factors, such as altitude, annual precipitation, annual mean temperature, and so on, which are suitable for the distribution of Swertia mussii in Sichuan. Ecological factors were obtained, superposition analysis and GPS field verification data were used to study the suitable distribution area of Swertia Swertia in Sichuan Province. The suitable distribution area was 1 543.749 km ~ 2 in Sichuan Province, which was mainly distributed in Dege County and Ganzi County. Daofu County, Kangding County, Malkang City, Jinchuan County, Xiaojin County, Danba County, Daocheng County, Xiangcheng County, Xinlong County, Aba County, Muli County, and other counties and cities, accounting for 7.25% of the total area of the counties and cities in this area, as well as field verification and investigation findings. The results showed that it was feasible to extract the suitable distribution area of Swertia mustioris based on remote sensing and GIS technology. It can be applied to the regional study on the suitability distribution of other rare Chinese medicinal materials.
