云南重楼作为一种常用的名贵药材,具有很高的药用价值,对其适宜分布范围进行研究,可为云南重楼的合理开发、人工种植栽培以及可持续利用研究提供依据。以四川省云南重楼为研究对象,根据相关资料文献,确定云南重楼的生态环境因子,应用遥感和GIS技术分别提取云南重楼适宜生长的海拔、坡度、坡向、年均温、年降水、植被和土壤类型等因子,将生态因子进行空间叠加、结合野外实地验证数据,提取云南重楼适宜分布区域及面积。结论:云南重楼的适宜分布区域总面积约为7 338 km2,占整个研究区域总面积的3.02%;主要集中分布在四川省的凉山州、阿坝州、甘孜州的色达县、攀枝花市、雅安市、成都市、眉山市、乐山市、宜宾市、内江市、泸州市、达州市、巴中市、南充市、广元市等市县区域;分析结果与野外实地验证数据具有较高的一致性,表明利用遥感和GIS技术提取适宜分布范围具有可行性。
As a commonly used precious medicinal material, Yunnan Zhonglou has high medicinal value, and its suitable distribution range is studied. It can provide the basis for the rational development, artificial cultivation and cultivation of Yunnan Lou and its sustainable use. Based on the relevant data and literature, the ecological environment factors of Yunnan re-arbor were determined based on the relevant data and literature. The remote sensing and GIS techniques were used to extract the suitable elevation, slope, aspect, annual average temperature and annual precipitation , Vegetation and soil types and other factors, ecological factors will be superimposed on the space, combined with field validation data to extract Yunnan re-floor suitable distribution area and area. Conclusion: The total area of suitable distribution area of Yunnan relic is about 7 338 km2, accounting for 3.02% of the total area of the study area. The distribution is mainly concentrated in Liangshan Prefecture, Aba Prefecture, Sichuan Province, Seda County, Panzhihua City, Ya’an City, Chengdu City, Meishan City, Leshan City, Yibin City, Neijiang City, Luzhou City, Dazhou City, Bazhong City, Nanchong City and Guangyuan City, etc. The analysis results are in good agreement with the field field verification data It shows that it is feasible to use remote sensing and GIS technology to extract suitable distribution range.
