摘要
本文探讨了三江平原小叶章草地地上生物量的季节动态,给出了小叶章草地两种主要类型草地地上生物量季节动态的模拟结果:小叶章沼泽草甸为B_1=115.5035-18.5653t+0.8012t^2;小叶章+修氏苔草草甸沼泽为B_2=166.5727-25.5288t+0.9531t^2.文章还探讨了这两种类型草地地上生物量的绝对和相对生长速率.
The seasonal dynamics of above-ground biomass of Deyeuxia angustifolia grasslands in Sanjiang Plain are discussed in this paper.With the help of the IBM PC/XT microcomputer,the simulation models of the seasonal dynamics have been made out. B_1 = 115. 5035-18. 5653t + 0. 80l2t^2 for Deyeuxia angustifolia swamp meadow. B_2 = 106. 5727 - 25. 5288t + 0. 9531t^2 for Deyeuxia angustifolia + Carax scbmidtii meadow swamp. In the last part of the paper,the absolute and relative growth rate of the above-ground biomass of the two types of the grasslands are delt with.
