【摘要】 全球气候变化正在改变冬季积雪深度,积雪作为固体淡水资源在全球部分地区水分平衡和水分利用中有着不可忽视的作用,积雪的变化受到了越来越多的关注。积雪的变化会引起土壤温度、湿度、植被生长、土壤微生物和土壤养分动态等显著改变。本文就积雪变化对森林土壤微生物的影响综述了国内外研究进展,着重介绍了积雪变化对土壤酶活性、土壤呼吸、土壤微生物生物量以及微生物群落产生的影响。文章为进一步研究积雪变化对森林土壤微生物的影响机制以及今后的研究方向提供了参考。更多还原

【Abstract】 Global climate change is changing the depth of snow in winter. Snow as a solid freshwater resource plays an important role in water balance and water use in some parts of the world.The change of snow has received more and more attention.Changes in snow cover can cause significant changes in soil temperature, humidity, vegetation growth, soil microbial and soil nutrient dynamics. In this paper, the effects of snow cover on forest soil microbes are reviewed. The research progress at home and abroad is emphasized. The effects of snow cover on soil enzyme activity, soil respiration, soil microbial biomass and microbial community are introduced. This paper provides a reference for further research on the mechanism of snow cover changes on forest soil microbes and future research directions.更多还原
