摘要: 采用分层随机抽样法,调查京杭大运河杭州段沿岸绿地植物物种组成,并分析其物种多样性指数。结果表明,京杭大运河沿岸市区段,乔木层和灌木层结构层次相对复杂,在生态系统中的地位较草本层显著;而在郊区段,草本层除了种类分布不均匀外,物种丰富度和多样性指数表明草本层物种丰富,在该生态系统中有较高的地位。

Abstract: Species composition of the Beijing\|Hangzhou Grand Canal in Hangzhou was investigated by typical sampling method, and species diversity index was analyzed. The results are shown as follows: the arbor layer and the shrub show more complexity than the herb layer in the community structure in the urban district; while the community structure of the herb layer is the richest in the suburbs and owed the highest position.
