摘要: |
通过样地调查,对星湖国家湿地公园湿地植物群落物种多样性进行分析,结果表明:样地有
湿地植物 22 科 31 属 34 种,其中蕨类植物 2 种,裸子植物 1 种,被子植物 31 种;21 个样地内草本层平
均有 3.14±1.56 个物种,Shannon-Wiener 指数(H "")、Simpson 指数(D)和 Pielou 均匀度指数(J)分别
为 3.305 1、0.042 6、0.945 2;不同植被型组草本层物种丰富度(S)表现为:草丛湿地>浅水植物湿地>
针叶林湿地;H "" 表现为:浅水植物湿地>草丛湿地>针叶林湿地;D 表现为:针叶林湿地>浅水植物湿
地>草丛湿地;J 表现为:针叶林湿地>草丛湿地>浅水植物湿地。优势湿地植物群系有落羽杉 Taxodium
distichum 群 系、 李 氏 禾 Leersia hexandra 群 系、 铺 地 黍 Panicum repens 群 系、 竹 节 草 Chrysopogon
aciculatus 群系、虾钳菜 Alternanthera sessilis 群系、密刺苦草 Vallisneria denseserrulata 群系、金鱼藻
Ceratophyllum demersum 群系、莲 Nelumbo nucifera 群系。保护好现有各类型的生境和植物群落,有利于
湿地公园生态系统的稳定和可持续。 |

Abstract: |
By sample-plot survey,species diversity indexes of wetland plants communities in Zhaoqing
Xinghu national wetland park were analysed. The results showed that there were 22 families, 31 genera and 34
species of wetland plants in sample plot, including 2 species of ferns, 1 species of gymnosperms, 31 species
of angiosperms; there were 3.14±1.56 species of herb layers in 21 sample plot on average; the index number
of Shannon-Wiener (H ""), Simpson (D) and Pielou (J) were 3.305 1, 0.042 6 and 0.945 2 respectively. Species
richness level of herb layer in different vegetation type groups: grass wetland > shallow-water plant wetland >
coniferous wetland. H "" index number: shallow-water plant wetland > grass wetland > coniferous wetland; D index
number: coniferous wetland > shallow-water plant wetland > grass wetland; J index number: coniferous wetland >
grass wetland > shallow-water plant wetland. The dominant wetland plant formations are Taxodium distichum,
Leersia hexandra, Panicum repens, Chrysopogon aciculatus, Alternanthera sessilis, Vallisneria denseserrulata,
Ceratophyllum demersum, Nelumbo nucifera.The protection of the existing habitats and plant communities is
conducive to the stability and sustainability of the wetland park ecosystem. |
