摘要: 研究了不同放牧强度对羊草草地的影响,结果表明,过牧条件下,群落地上、地下生物量分别比轻牧阶段下降了67.96和75.00%,羊草种群根茎分蘖数和种子产量下降1.0和3.3%.极牧条件下,土壤有机质和水分含量分别下降到轻牧阶段的21.1和66.5%,而碱化度和全盐量却分别增加了1倍和8倍。
关键词: 放牧演替, 羊草草地, 松嫩草原
Abstract: Studies on the effect of different grazing intensities on A.chinense grasslands show that in comparing with light grazing, above-and underground biomass of the community is decreased respectively by 67.96 and 75.00%, and tillers number of root stocks and seed production of A.chinease are decreased by 1.0 and 33X, under overgrazing condition.Under extreme grazing condition, soil organic matter and water content are decreased by 21.1 and 66.5%, and the alkalinity and total salt are increased by one and eight times,respectively.
Key words: Grazing succession, Aneurolepidium chinense grassland, Songnen grassland
