现代冰川雪冰中的微粒是重建过去气候环境变化的一项重要替代性指标。根据前人对极地冰盖和山地冰川冰芯及雪坑样品中的微粒粒径、矿物特征和含量变化等研究成果，讨论了微粒粒径变化，微粒与火山活动、大气气溶胶的关系，以及冰芯测年、微粒来源等相关分析，认为微粒中的代表性矿物、火山玻璃、粗糙系数和粒径分布可作为确定微粒源区的指标；微粒含量的变化与大气环流、气温高低及干湿程度密切相关，微粒含量的高值对应冷干气候，反之为暖湿；大气环流加强时，微粒含量增加，反之减少。微粒研究还能获得如火山活动、人类影响等特殊事件的信息 Particles in the snow and ice of modern glaciers are an important alternative indicator for reconstructing the past climate and environment. Based on the previous research results on particle size, mineralogical characteristics and content of ice cores and snow pits in polar glaciers and mountain glaciers, the changes of particle size, the relationship between particles and volcanic activity and atmospheric aerosols are discussed, and Ice core dating and particle source analysis. It is considered that the representative minerals, volcanic glass, roughness coefficient and particle size distribution in the microparticles can be used as the indicators to determine the source region of the microparticles. The variation of the microparticle content is related to the general circulation, temperature, The degree is closely related to the high value of particle content corresponds to cold and dry climate, on the contrary, warm and humid; enhanced atmospheric circulation, the particle content increases, and vice versa decreases. Particle research also provides information on specific events such as volcanic activity, human effects, and more
