Abstract

Abstract: Measurement of the aboveground biomass of Kobresia humilis meadow indicated that the aboveground biomass reaches half value of the maximal yield of this growth season in the second ten days of June and the growth rate of community ,the leaf area increasing rate and the leaf area ratio almost reach maximum.The growth redundancy of the community is following after middle June and correspondent with the results calculated from Logistics’formula.

Key words: Kobresia humilis meadow, Growth redundancy, Compensation

摘要： 对海北站封育矮嵩草草甸地上生物量定期测定结果表明,地上生物量在6月中旬达到最大产草量的半值,此时,草甸群落生长速率、叶面积增加速率和叶面积比率接近最大值。6月中旬以后,草甸群落进入生长冗余时期。结果与逻辑斯缔方程理论推算的结果相一致。
