摘　　要：【目的】利用国产卫星资源三号影像,选取新疆阿勒泰阿拉哈克乡野生罗布麻自然保护区,进行药用植物宏观监测分析评估。【方法】采用遥感与地面调查相结合的方法对野生罗布麻进行遥感识别,在传统分类方法中加入PCA(第一主分量)和纹理特征作为辅助数据来提高国产卫星对野生罗布麻进行遥感识别的分类精度。【结果】利用遥感影像分类提取野生罗布麻效果较好,总体分类精度为90.23%,kappa系数为0.8658,但是罗布麻的生产者精度只有73.09%,存在漏判现象。【结论】分析漏判原因,并对国产卫星资源三号是否适用于野生药用植物宏观监测做出评价。[Objective] This project aim to investigate such resources of medicinal plants as wild apocynum,etc.[Method] Supervised classification based on Principal Component Analysis （PCA） and texture feature were used to obtain the wild apocynum acreage from image captured by ZY-3.[Result] The research result showed that the accuracy of RS image classification was 90.23% and the kappa coefficient was 0.8658,but the producers accuracy of wild apocynum was only 73.09%,which told us that a certain missing judgment might exist in the process.[Conclusion] After analyzing the reasons for the missing judgment,the author evaluated the applicability of domestic satellite ZY-3 on monitoring the resources of wild medicinal plant.
