| 摘 要： | 研究了杭州西湖种质资源保护区的莼菜种群和群落的基本特征。结果表明,西湖莼菜保护区中间区域的物种多样性低于近岸区域,而莼菜的盖度高于近岸区域;莼菜的群落结构和无性繁殖方式可能是导致低的遗传多样性的重要原因。

| Abstract: | Population characteristics and community characteristics of the endangered aquatic Brasenia schreberi at conservation zone of West Lake in China were surveyed.The results showed that species diversity of the middle zone with high coverage in B.schreberi was lower than that of the shore zone.Community characteristics with asexual reproduction were the most important cause of low levels of genetic diversity in B.schreberi population at the conservation zone of West Lake,China. |
