【摘要】 对不同放牧强度下高山嵩草草甸植物群落变化的研究,结果表明,随着放牧强度的增加,高山嵩草总分蘖数、秆分蘖数减少,但均高于对照区,而侵入种的种数趋于增加,在放牧区内9月份达到最高值,不放牧区8月份达到最高值。复合分蘖数8月份达到最高值,芽分蘖数及其叶片数7月份达到最高值。单分蘖数和秆分蘖数均在5月份达到最高值,秆分蘖叶片数5月份达到最高值。更多还原

【Abstract】 The variation of Kobreisa Pygmaea plant population under different stocking intensity in Alpine meadow was studied. The results showed that the number ofthe total tillers,productive tillers which was higher than the control plot and the total invade plants decreased as the increase of grazing intensity. It reached to the maximum in September with grazingplot and nograzingplot in August. The composite tillers rose tothe maximumin August,shoot tillers and its leaves in July, single tillers, production tillers and its leaves in Mayrespectively.更多还原
