摘要: 本文对肇州羊草+杂类草群落主要种群、种组及群落数量特征季节动态进行了探讨。结果表明,在生长季内,羊草、蔓委陵菜群种及丛生禾草种组高度和盖度,群落的盖度及密度特征呈单峰型变化,群落最大地上生物量出现在8月5日,其值为197.3g/m2干物质,而后下降;在生长季内,符合拓广了的Logistic模型增长,其模型为:B=B=224.6038/1+e5.9289-5.5388×102·t-4.8484×104·t2+3.5365×106·t3

关键词: 羊草+杂类草群落, 数量特征, 季节动态

Abstract: This study was carried out in Zhao zhou, Hei Longjang.The quantity characterstics seasonal dynamics of the main population, population group and community of Aneurolepidium chinese+herbs community were described.The results showed that the height and coverage of Aneurolepidium chinense.Potentilla flagellaris Population and grow thickly herbs population group, and the coverage and density characteristics of the community appeared as single peak form in growth season.The maximum aboveground biomass was 197.3g/m2 dry matter (DM) occurred on August 5 and then declined.It conformed to the developed logistic model in the growing season, its developed logistic model was:B=224.6038/1+e5.9289-5.5388×102·t-4.8484×104·t2+3.5365×106·t3

Key words: Aneurolepidium chinese+herbs community, Quantity characteristics, Seasonal dynamics
