目的：：比较不同产地石膏扫描电镜观察结果。方法：采用扫描电镜对不同产地石膏样品进行观察。结果：不同产地石膏(CaSO4·2H2O)晶体结构呈紧密纤维集合、板状或片状层叠，具光泽。其中，湖北产道地药材石膏放大表面有明显黑色斑点，其他产地石膏无此特征。结论：扫描电镜法简便易行，准确度高，可用以鉴别石膏，并用于湖北道地产区石膏与其他非道地产区石膏的识别。

Objective:To investigate gypsum fibrosum from different habitats by scanning electron microscopy ( SEM) . Methods:Gypsum fibrosum samples from different habitats were scanned by an electronic microscope. Results: The results of SEM showed that gypsum fibrosum (CaSO4·2H2O) from different habitats was with the crystal structure of fibrous,tabular or flaky aggregation. The sur-face amplification of gypsum fibrosum from Hubei showed obvious black spots,while that from the other habitats was without the feature. Conclusion:The method is simple and accurate, which can be used to investigate gypsum fibrosum from different habitats.
