摘要
对三江平原沼泽化草甸小叶章群落生物量进行研究;结果表明,沼泽化草甸小叶章群落生物量季节动态呈抛物线型,生物量最大值出现在7月末,为326.00 g/m2;生物量累积生长量季节动态呈单峰型,最大积累量334.75 g/m2;生物量生长量、生物量绝对增长率和相对增长率季节动态都呈"Z"型,其最大值出现在7月末,分别为238.39 g/m2,7.95g/d,0.1825g/g.d。
Biomass of Calamagrostie angustifolia communities in swamped meadow of Sanjiang Plain is studied, The result shows as followed： the curve of seasonal dynamic law of the biomass is parabola, Maximum biomass occurred at the end of July, that is 326.00 g/m^2; Curve of accumulated biomass growth is singlet, of which maximum is 334.75 g/m^2. Curve of biomass accretion, absolute growth rate and relative growth rate show ＂Z＂ type, of which are 238.39 g/m^2, 7.95 g/d and 0.1825 g/g·d respectively. They all occurred at the end of July.
