摘　　要：为了分析西北地区城市公园植物配植组成的多样性,采用指标分析方法,对乌兰察布市6个公园进行调查研究。结果表明:6个公园中除白泉山公园外,Margalef指数均为乔木层>灌木层,榆树湾公园的物种丰富度最低;乔木层和灌木层的生态优势度指数普遍偏高,其中霸王河公园乔灌木层的Simpson指数相差最大;Shannon-Wiener指数在某种程度上变化趋于一致,乔灌木层的不确定性差别都较大;平均密度的分析表明公园内的植物种植密度普遍偏大。指出了乌兰察布市公园建设存在植物选择面小、设计理念不合理、植物配植不丰富等问题。基于此,提出了在该地区公园的建设及后期的景观提升工作中,应采取适地适树的举措,保持和恢复植物多样性,从而发挥公园保障城市景观,促进城市生态健康可持续发展的重要作用。In order to analyze the diversity of species composition in urban parks in northwest China,6 parks in Ulanqab City were investigated by index analysis method.The results showed that the Margalef index of all the six parks except Baiquanshan Park was tree layer>shrub layer.Yushuwan Park had the lowest species richness..The ecological dominance index of tree layer and shrub layer is generally high,and the Simpson index of tree layer in Bawanghe Park has the biggest difference.Shannon-Wiener/Simpson index of species diversity tends to be the same to some extent,and the uncertainty difference of tree and shrub layer is large.The analysis of average density shows that the plant planting density in the park is generally too high.The prominent problems of limited plant selection,unreasonable design concepts,and insufficient plant species allocation in the construction of Ulanqab City Park have been exposed.Based on this,it is proposed that in the construction of parks in this area and the later landscape improvement work,measures should be taken to maintain and restore plant diversity,so as to play the important role of parks in protecting urban landscape and promoting the healthy and sustainable development of urban ecology.
