摘要
调查了山西省滹沱河河漫滩草地苔草群落的结构和生物量,结果表明:苔草群落的总生物量为13738kg/hm2,其中地上部分(叶、茎)生物量为3388kg/hm2,地下部分(根)生物量为10350kg/hm2。建群种针状苔草、披针叶苔草的生物量为5008kg/hm2,占群落总生物量的36.46%。群落地上生物量与地下生物量的比值为0.33。此外,还讨论了种的生物量与生物学特性以及群落组成结构与生物量的关系。
The biomass and structure of Carex dispalata community distributed in Hutuo Rivers wetlands,Daixian county,Shanxi were studied by harvest method, the results indicated that the total biomass of the community is 13738kg/hm2 including the aboveground (leave and stem) 3388 kg/hm2 and the underground (root) 10350kg/hm2.The biomass of Carex lanceolata,C.duriuscula being constructive species was 5008 kg/hm2 totally, accounting for 36.46% in the total.The relationship between the biomass and biological character of species and structure of the community was discussed in the paper.
