中文摘要: |
花溪河地处喀斯特山区贵州省贵阳市郊,该河流水质清澈,大型水生植物丰富,水生生态保持较好。2007年9—10月,对花溪河的水生植物群落及其物种多样性进行了初步调查。结果显示:花溪河中有水生植物11科15种,其中苦草(Vallisnerias piralis)、马来眼子菜(Potamogeton malaianus)、水车前(Ottelia alismoides)、轮叶黑藻(Hydrilla verticillata)、五针金鱼藻(Ceratophyllum oryzetorum)、空心莲子草(Alternanthera philoxeroides)和石菖蒲(Acorus gramineus)为优势种群。就优势种生物量而言,苦草达到370.50g/m2、马来眼子菜达到478.00g/m2、水车前达到191.10g/m2。茂盛的大型水生植物使花溪河的水生生态保持在良好的水平。

Huaxi River locates in the suburb of Guiyang city, Guizhou province The water ecological system is well with good water quality, and abundant aquatic macrophyte in the river. Aquatic plant population and species diversity were investigated from Sept to Oct, 2007. Results showed that there were 15 species of aquatic plants belonging to 11 families in Huaxi River. Among them, Vallisneria spiralis, Potamogeton malaianus, Ottelia alismoides, Hydrilla verticillata, Ceratophyllum orzetorum, Alternanthera philoxeroides and Acorus gramineus were the predominant species. The biomass of Vallisneria spiralis, Potamogeton malaianus and Ottelia alismoides reached 370.50 g/ m2, 478.00 g/m2 and 191.10 g/m2, respectively. Flourish aquatic plants kept water ecological system of Huaxi River at a nice level. |
