摘要
草原火刺激克氏针茅和扁穗冰草提前返青，促进扁穗冰草的生长发育，使其盖度、密度、产量等提高，而对克氏针茅产生不良效果，使其密度、盖度、产量等下降。
The rusults showed that grassland fire made Stipa krylovii and Agropyron cristatum’s returing green period advanced, promoted the growth of Agropyron cristatum, and increased its coverage, density and yield. Grassland fire showed negative effect on Stipa krylovii, reduced its coverage, density and yield.
