通过实地观测国家体育场冬季冰雪节人造雪覆盖条件下的草坪生长状况，研究了冬春季人工覆雪模式的影响及其可行性。结果表明，覆雪状态下草坪草比同时期未覆雪草坪草的可溶性糖含量、细胞膜透性都显著降低，根系活力相对增高，叶绿素含量在前期趋于一致、后期较高，覆雪对草坪草的冬季生长和返青有明显促进作用。但当雪层较薄低于30 cm 以下时，保温保湿作用大幅降低，同时还会因为雪融化结冰而对草坪产生负面影响。就草坪草冬春季的稳定性而言，无雪覆盖>厚雪(60~70 cm)覆盖>薄雪覆盖(<7 cm)；对返青的促进作用而言，厚雪覆盖>无雪覆盖>薄雪覆盖。

The impact of artificial snow covering on the quality,root vigor,physiology and metabolism of football turf in winter and spring was studied in National Stadium.The results indicated that the soluble sugar content and cell membrane permeability of turfgrass were significantly reduced by snow cover,the root vigor was relatively increased,the chlorophyll content was the same at first and higher later.The snow cover could ob-viously promote the turfgrass physiology and quality.But when the snow thickness was thin (below 30 cm),the effect reduced greatly,Meanwhile,the melting of snow and icing had a negative impact.For the stability order of the turfgrass growth was,no snow > thick snow > thin snow,and it was thick snow > no snow > thin snow for promoting regreening rate,.
