摘要/Abstract

摘要： 泥炭地作为环境变化的敏感带，成为当前环境气候研究的热点之一。植硅体的抗腐蚀、耐高温、个体小、产量高的特点为第四纪环境变迁的研究提供了有效途径。相比孢粉分析而言，植硅体在提高分辨率和恢复局部区域环境方面体现了其优越性。对泥炭沉积中的植硅体进行了分析，初步证实植硅体对重建泥炭地古环境变迁模式起着重要的作用，对提高古气候变化的分辨率有很大的帮助。

Abstract: Phytolith plays an important role in the study of paleobotany and paleoenvironment because of its small, high yield, and its ability of antierosion and hightemperature resistant. As a sensitivity zone indicating environmental changing, peat bog has become one heated topic in climatic and environmental research. The significance of phytolith in peat deposit is discussed. 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.

Key words: phytolith, pollen analysis, peat deposit, environmental change
