Abstract 【Objective 】This project aims to explore resources of medicinal plants in China based on remote sensing technology. In this paper, we took Carthamus tinctorius L as the research object to explore resources of medicinal plants in China based on remote sensing technology.【Method 】We selected a A typical region rich in safflower (Carthamus tinctorius L.) in, Jimsar County of Changji Hui Autonomous Prefecture in Xinjiang was selected, as the sample plot. On In this area,we got some features of habitat of Carthamus tinctorius L. through filed survey by remote sensing technique were obtained. For the first time, ZY - 3 satellite images had been chosenwere adopted to finish our interpretation work. Finally, we preprocessed these images and produced the classified figures by the method of maximum likelihood supervised classification based on principal component analysis and texture features.【Result】The results showed that sample accuracy rate was 68.75%,the overall classification accuracy was up to 68. 757% and the Kappa coefficient was 0. 573. The classification result was moderate consistency.【Conclusion 】Generally,we could infer that it is feasible to use ZY - 3 satellite to explore resources of medicinal plants, such as Carthamus tinctorius L. However,there are some difficulties in interpreting medicinal plants by using remote sensing techniques.
