New information on the response of vegetation to air-fall volcanic ash is provided by analysis of phytoliths from sediments containing major tephra beds. 含火山灰層沉積的植硅體分析為了解植被對從空中下降的火山灰的反應提供新的信息。
It shows that phytolith has its own advantage in paleo-evironmental reconstruction of peat bogs, and will be of great help in discriminating the palaeo-climatic change. 對泥炭沉積中的植硅體進行了分析，初步證實植硅體對重建泥炭地古環境變遷模式起著重要的作用，對提高古氣候變化的解析度有很大的幫助。
