柳州市东堤游园滨水绿地植物群落研究

对柳州市东堤游园滨水绿地植物群落的物种组成（Simpson指数）、物种多样性指数（Shannon-Wiener指数）、群落相似性系数（Jaccard相似性系数）等进行分析研究。结果表明，东堤游园滨水绿地植物群落中乔灌木种类丰富，但地被植物种类较少，尤其是水生植物景观较单一。滨水绿地植物配置以乡土植物为主，其中观赏价值高的乔灌木的应用频率及物种多样性相对较高；不同植物群落问物种组成存在明显的差异。该研究为城市滨水绿地植物景观的生态建设与保护提供了一定的科学依据和参考借鉴。

Study on the Plant Communities of Waterfront Green Space in Liuzhou Dongdi Garden

Species of plant communities(Simpson index),species diversity index(Shannon-Wiener index),as well as community similarity index(Jaccard index) of waterfront green space plant communities of Dongdi garden in Liuzhou were analyzed.And the research result were as follow: the species of tree layer and shrub layer were abundant,but the ground cover plant layer was less,especially the aquatic plant landscape was relatively simple;most waterfront green space plant disposition was native plants,where there was relatively high application frequency of the high ornamental value trees and shrubs;the species were diversified and there were significant different species compositions between different plant communities.The study provided scientific basis and reference for the construction and protection of the urban waterfront green plants landscape.
