南通濠河滨水绿地植物群落多样性研究

Research on Plant Community Diversity of the Waterfront Regions of Hao River in Nantong

为改造滨水绿地植物景观,发挥其生态功能,以南通濠河滨水绿地为研究对象,采用典型抽样法,通过对各绿地植物组成以及群落丰富度、多样性、均匀度进行比较分析。结果表明,调查样地27个样方共有植物52科93属118种,三处不同类型滨水绿地植物丰富度Gleason指数、多样性Simpson指数、均匀度Pielou指数均为乔木层>灌木层>地被层>水生植物,生态型滨水绿地乔木层的三种多样性指数中均最高,灌木层的Gleason指数最高;游园型滨水绿地地被层及水生植物的3种多样性指数中均最高,灌木层在Simpson指数、Pielou指数中最高;广场型滨水绿地各层次植物多样性参数均最低。

For transforming the waterfront green space and play its ecological function ,taking Hao River water-front green space in Nantong as research object ,the species composition and diversity index of plant community in the waterfront regions of Hao River in Nantong were analyzed and compared by typical sampling method . The results showed that the plant species of the waterfront regions involved 52 families ,93 genera and 118 spe-cies .Three indexes of Gleason index ,Simpson index and Pielou index appeared as arbor layer＆gt; shrub layer＆gt;ground cover＆gt;water plants .For ecological water region ,the maximums of three index were in the arbor layer , and the maximum Gleason index was in the shrub layer .And for park water region ,the maximums of the three index appeared in the shrub layer and water plants ,the maximums index of Simpson and Pielou were in the shrub layer .For square water region ,the minimums of the three index were in all lays of plants .
