摘　　要：该文综述了高山积雪对植物个体、种群及群落等生态特征影响的研究进展。从研究结果来看,积雪的厚薄与融雪的早迟对植物的生长及繁殖物候具有较大的影响,同时会对植物的叶、株高、种子数、单株生物量及花形态结构等个体特征产生影响。雪被会使植物种群的分布格局和种间联结性发生变化,影响群落的物种多样性和生物量的分布。从地域来看,欧洲、北美及日本的研究较多,中国的研究较少;从研究领域来看,关于植物个体特征方面的研究较多,而种群及群落方面的研究较少。今后在高山雪生态学方面的研究中,应在种群及与群落等宏观方面有所加强。我国应在青藏高原东部地区开展更多的研究工作。This article reviews some progress in research work of alpine snow ecology,including individual,population and community.Snowpack thickness and snow melting time exert evident effects on plants'phenological phase of growth and reproduction,and on leaves,height,biomass,flowers and seeds of a single plant as well.Besides,snow cover changes population distributing pattern and interspecies association,and affects species diversity and biomass in a community.Regionally,more research work was carried out in Europe,north America and Japan.However,China did less work in the past decades.As far as research field was concerned,more work was carried out in individual traits,with less in population and community.In the future,more macroscopic ecological research should be considered and carried out in eastern Qinghai Tibetan plateau in China.
