摘　　要：在调查的基础上,将徐州地区河岸带绿化结构分为5类,并计算了河岸带植被的Shannon—Wiener多样性指数。研究结果表明,城市地区与农村地区在河岸带绿化结构上差异明显,城市的河岸带结构以园林绿化型和高挡墙型为主,农村以种植型为主;在河岸带植被多样性方面,农村与城市的木本植物的多样性相差不大,但农村河岸带草本植物多样性显著高于城市;不同类型河岸带绿化结构对于河岸带植被多样性也有一定的影响,乔木的多样性差别不大,高挡墙型河岸带的灌木多样性明显高于其它类型,而在草本植物多样性方面,种植型河岸带是最高的;同时,河岸带宽度对河岸带绿化结构具有重要影响。最后对徐州地区河岸带的改造提出了相关建议。Based on investigation,greening structure on riparian zone of Xuzhou area is divided into five categories,and Shannon—Wiener diversity index of the riparian vegetation is quantified.The study shows that there are significant differences between urban area and rural area in the riparian structure.The riparian structures in urban area are dominated by the types of garden and high-grade wall,and plantation is the main type of riparian structure in rural area.The diversity of woody plants in rural area is similar to that in urban area.But in rural area,there is higher herb diversity than the one in urban area.The riparian structure types have remarkable effects on the riparian vegetation diversity.The diversity of trees varies slightly among different structure types.The type of high-grade wall is significantly higher than other types in shrub diversity,and the type of plantation takes highest grass diversity.The riparian width gives a significant impact on riparian structures.At last,some suggestions on the transformation of riparian zone in Xuzhou area were given.
