大叶藻海草床的生态恢复：根茎棉线绑石移植法及其效果
Transplantation of eelgrass (Zostera marina L.) in Huiquan Bay using rhizomes bound to a small elongate stone with bio-degradable cotton thread
摘要
Abstract
The eelgrass (Zostera marina L.) was transplanted with a new simple method in Huiquan Bay, Qingdao, i.e several rooted shoots tied on a small elongate stone with cotton thread were planted in 2009 and 2010. From April 20 to November 19, 2012, the morphology, shoot density, shoot height, aboveground biomass and particle-size of sediment of the transplanted eelgrass were observed. The water temperature ranged from 7.8 to 26.1℃ during the observation. The results showed that the sexual reproduction of eelgrass occurred from April to August, and that the asexual reproduction occurred frequently in autumn. The mean shoot density ranged from 240 to 481 shoots/m2, with relative higher values of 411 shoots/m2 and 481 shoots/m2 in June and September, respectively. The highest values of shoot height and aboveground biomass occurred in June to July. The sediment was characterized by silt. The values and variations of shoot height and aboveground biomass were similar with those of natural eelgrass in Qingdao Bay, observed in 2009. We conclude that the transplanted eelgrass grew well, suggesting that the new method was effective and practical.关键词
