摘　　要：目的:探讨遥感技术在野生稀有种植物资源调查的有效性和可行性。方法:综合遥感、数字高程模型、样方调查和植物生态学特性建立新疆芍药空间分布遥感解译专家知识模型辅助资源调查。结果:获得研究区新疆芍药的生长适宜地。结论:野外验证其总体解译精度可靠,满足资源调查的要求。Objective： To study the effectiveness and feasibility of remote sensing technology in the rare species of wild plant resources. Method： The mechanism and characteristics of Paeonia sinjiangensis were analyzed to find the possibility of extracting from TM imagery. An expert system has been used with Landsat Thematic Mapper data to derive P. sinjiangensis. Then logical decision rules were used with the various datasets to assign values. Result： The land for P. sinjiangensis possible growth were mapped and ac- curacy tested was approving. Conclusion： The results suggest that the remote sensing expert interpretation system using satellite imagery and ancillary data will be feasible for research of rare wild medicinal plants distribution.
