摘要(Abstract):

采用样方法分析了利川莼菜种质资源原生境保护区的莼菜居群和群落的组成及结构。结果显示,利川莼菜保护区近岸区域的物种多样性比中间区域高,而莼菜的盖度则是近岸区域低于中间区域。莼菜遗传多样性较低,可能与生境片断化和无性繁殖密切相关。
Population and community structures of Brasenia schreberi at conservation zone of Lichuan in China were analysed using quadrat method. Species diversity of B. schreberi in the shore zone is higher than the middle zone. Low level of genetic diversity in B. schreberi populations at the conservation zone of Lichuan is closely related to the habitat fragmentation and asexual reproduction.
