摘要
调查了山西省滹沱河河漫滩湿地假苇拂子茅群落的结构和生物量，结果表明，假苇拂子茅群落的总生物量为７４５．４ｋｇ／ｈｍ２，其中，地上部分（叶、茎等）为４４８．１ｋｇ／ｈｍ２，地下部分（根）为２９７．３ｋｇ／ｈｍ２。建群种假苇拂子茅的生物量为５４５．４ｋｇ／ｈｍ２，占群落总生物量的７３．１７％。此外，还讨论了生物量与群落结构的关系。
The biomass and structure of Calamagrostis pseudophragmites community distributed in Hutuo River's wetlands,Daixian County,Shanxi were studied by harvest method,the results indicated that the total biomass of the community is 745 4 kg/hm 2 including the aboveground (leave and stem) 448 1 kg/hm 2 and underground (root) 297 3 kg/hm 2.The biomass of C. pseudophragmites being constructive species was 545 4 kg/hm 2,accounting for 73 17% in the total.Finally,the relationship between the biomass and structure of the community was discussed in this paper
