摘    要:研究了梁湖子湖之一满江湖的六种沉水植物种群数量和生物量在1997.3-1998.3的月动态。结果表明:满江湖沉水植物群落中,优势种为黄丝草、金鱼藻和穗状狐尾藻;六种沉水植物种群最大密度、最大单位面积生物量出现的月份各不相同,但两者变化的趋势一致。黄丝草、穗状狐尾藻种群为增长型种群,金鱼藻、苦草、黑藻种群稳定发展,菹草种群有衰退的趋势。沉水植物群落的最大生物量达到4676g/m^2(鲜重,10月),

关 键 词:沉水植物  种群数量  生物量  周年动态  梁子湖

Abstract:This paper deals with the quantitative and biomass dynamics of six submerged macrophyte populations in Manjiang region, Liangzi Lake from March 1997 to March 1998. In the submerged macrophytes community, the dominant species were Potamogeton maackianus, Ceratophyllum demersum, Myriophyllum spicatum. The maximum densities and biomass of six populations appeared in different months within the growing season. The biomass varied with the densities. After the growth season, P.maackianus population and M. spicatum population tended to increase continuously, but that of C. demersum, Vallisneria spiralis and Hydrilla verticillata could develop steadily, and P. crispus population had a tendency of decreasing. The maximum biomass of submerged macrophytes community reached 4676g/m 2 (fresh weight, in Oct.), and the maximum density was 1865 branch/m 2 (in Nov.). Annual quantitaive dynamics were modelled for six macrophytes both seperatedly and totally by using data from March 1997 to December 1997.
