摘 要：
研究了不同施氮水平下克氏针茅草原群落地上地下生物量的分配格局。结果表明,氮素的添加明显改变了克氏针茅群落的地上地下生物量分配。施氮对群落地上生物量的影响较大,同时也使群落减少了对地下生物量的分配,但是不同施氮梯度对地下生物量各层分配的总体影响不大。

摘 要：
Under the different nitrogen additions,biomass allocation for Stipa krylovii community ground and underground was investigated.The result showed that the nitrogen additions obviously can improve biomass allocation for Stipa krylovii community ground and underground,especially to ground biomass,meanwhile the community belowground biomass allocation was reduced,but different levels of underground biomass allocation were little affected by nitrogen gradients.
