中文摘要:
      冰雪灾害是一种常见的自然灾害,易对森林造成巨大破坏。在全球变化加剧的背景下,冰雪灾害发生的频率和强度呈现上升趋势。文中综述了冰雪灾害后森林土壤物理性质、土壤化学性质、土壤微生物群落和土壤酶活性的变化,以便为受损森林生态系统的修复提供参考。今后的研究热点是加强对灾后森林养分循环、土壤微生物和土壤种子库的长期研究,开展土壤微生物群落、土壤呼吸和土壤理化性质相互关系及作用机理研究,运用3S技术监测不同立地条件下土壤灾后动态变化、建立更科学精准的受灾森林生态系统评估体系,以及建立生态修复模型预测冰雪灾害后的森林恢复过程。
英文摘要:
      Ice-snow is a common natural disaster, and it often causes huge damages to forests. The frequency and intensity of ice-snow damage tend to rise under the background of global warming. To provide a basis for the restoration of damaged forest ecosystems, this paper reviewed the change in soil physical and chemical properties, soil biochemical properties, soil microbial community and soil enzyme activity after ice-snow damage. It came up with the future research direction, including the long-term research on forest nutrient cycling, soil microorganism and soil seed bank after ice-snow disasters, the research on the interaction and working mechanism between soil microbial community, soil respiration and soil physical and chemical properties, monitoring post-disaster changes in soil under different site conditions using 3S techniques, establishment of a more scientific and accurate assessment system for damaged forest ecosystems, and setting up ecological restoration models to predict forest restoration process after ice-snow damage.
