摘要
研究利川不同类型莼菜种群和群落的基本特征。结果表明:人工群落的物种多样性低于半野生群落,而有较高的莼菜多度和盖度。人工定植管理可能是导致莼菜群落的物种多样性降低的重要原因。
Population characteristics and community characteristics of the endangered aquatic Brasenia schreberi at Lichuan in China were surveyed.The results showed that species diversity of planting community with high abundance and coverage in B.schreberi was lower than that of semi-wild community.Excessive cultivation was the most important cause of low levels of species diversity in B.schreberi community.
