基于遥感技术的甘草资源调查方法研究

目的以甘草为研究对象,以遥感技术为基础,探索野生药用植物资源调查的方法。方法通过对确定的研究区域进行遥感调查,确定调查的最佳技术方案。结果确定了基于遥感并结合野外抽样的甘草资源调查方法,包括遥感信息源的选择、图象的处理、解译、野外验证等。结论采用中等分辨率的卫星影像ETM(15 m)量测,并计算出甘草分布的面积和蕴藏量,判读精度高于90%,表明该遥感调查方法用于甘草的野生资源调查是可行的。

Resources survey of Glycyrrhiza uralensis based on remote sensing technique

ive: Objective To explore the survey methods based on remote sensing technique for the wild medicinal plant resources such as Glycyrrhiza uralensis.Methods Through the preliminary study by remote sensing technique in designated area,the optimal methods in the procedure for the survey were selected.Results In this study,a set of survey method for G.uralensis based on remote sensing technique was found,which included the remotely sensed data-source selecting,the remote sensing image processing,interpretation,and validation,etc.Conclusion By the medium space resolution remotely sensed data-source ETM(15 m),the distribution area and the natural storage of G.uralensis are obtained,and the classification accuracy is more than 90%,which shows that the method is feasible for resources survey of wild medicinal plants,such as G.uralensis.
