摘 要:该文综述了雪被对生态系统中各组成成分的影响。雪被能够改变雪下光线强度、雪下温度、土壤水分等生态因子,从而也使得雪被对生态系统中的雪下微生物、雪生动物和雪生植物的生长和繁殖等生命活动产生影响。另外,雪被还对生态系统中的营养成分如氮、磷等产生较大影响。由此可见,雪被对生态系统中的生物成分和非生物成分都会产生深刻影响。当前积雪对生态系统中环境因子和生物成分的影响研究较为深入,但在物质循环和能量流动方面还需加强研究。Research results of effects of snow cover on components of ecosystem were summarized in this paper.Snow cover changed light intensity,temperature and soil moisture under snow cover,so that living activities such as growth and reproduction of microorganisms,animals and plants in snow ecosystem were affected.In addition,snow cover greatly influenced nutrient composition including N and P in snow ecosystem.Obviously,snow cover exerted evident effects on both biological and non-biological components in snow ecosystem.In conclusion,the research on environment factors and biological components in snow ecosystem goes deeper,while the research on material circu⁃lation and energy flow is weak and it needs to be strengthened in the future.
