本文提出了利用扩展焦深(EDF)图像测量和直接显微镜下测量两种方法对商周时期和营遗址的植物硅体进行形态类型分析，并对两种方法的结果进行了比较。对比表明，这两种方法在古环境分析和农业分析中的结果是一致的。两种方法的结果表明，根据某些特定的植硅体组合的优势，和营遗址的环境应该是温暖和潮湿的。植硅体的形态类型来源于农作物，也表明水稻种植是农业经济的支柱。相比之下，基于EDF图像的形态分析方法仅需原方法的1/10左右，直接在显微镜下测量。这样，我们就可以在相同的时间内处理更多的样品，进行更全面、更系统的植硅体形态分析。此外，构建的EDF图像还可以存档，以供将来考试和教育使用。以上实验表明，基于EDF图像的形态分析方法在植硅体分析中具有很好的应用前景。Microsc.技术资源。2011年。©2011 Wiley期刊，Inc.
In this article, we propose to make morphotypological phytolith analysis of Heying site during Shang‐Zhou Period by two methods: measuring based on extended depth of focus (EDF) image and measuring directly under microscope, and then compare their results. The comparison shows that the results by these two methods match each other for paleoenvironmental and agricultural analysis. Results of two methods show that Heying site's environment should be warm and moist based on the predominance of some specific phytolith assemblages. The phytolith morpho‐types originated from crop plants also indicates that rice planting was the mainstay agricultural economy. In comparison, the morphotypological analysis method based on EDF image took only about 1/10 the time as the original method by directly measuring under microscope. Thus, we can process more samples and make a more thorough and systematic morphotypological phytolith analysis with the same amount of time. Furthermore, the constructed EDF image can also be archived for future examination and for education. The above experiments indicate that the morphotypological analysis method based on EDF image is very promising for phytolith analysis. Microsc. Res. Tech. 2011. © 2011 Wiley Periodicals, Inc.
