摘　　要：以宣城市10个公园内148个样地为研究对象进行公园绿地树木多样性分析,结果表明:有绿化树种171种,隶属于69科121属,蔷薇科树种最多,有11属17种;重要值最大的乔木是香樟,灌木是垂丝海棠,分别为37.236、10.322。乔木树种丰富度指数较高是敬亭湖公园(3.611)和鳌峰公园(3.607),较低的是府山广场(1.276)和昭亭广场(1.028);灌木丰富度指数较高是敬亭湖公园(3.348)和鳌峰公园(3.294),较低是府山广场(0.962)和昭亭广场(0.910)。乔木Simpson指数与Shannon-Wiener指数具有一致性,最高是响山公园(分别为0.900和2.512),最低的是昭亭广场(分别为0.571和0.956),其他相差不大;灌木Simpson指数与Shannon-Wiener指数也具有一致性,最高是鳌峰公园(分别为0.896和2.461),与敬亭湖公园(分别为0.894和2.480)接近,最低是昭亭广场(分别为0.568和0.937)。乔木和灌木Pielou均匀度指数最高均是鳌峰公园,最低均是泥河公园。The result of the research of park green tree species diversity based on 148 sampled plots in 10 parks in Xuancheng City shows that there are 171 kinds of tree species, belonging to 69 families and 121 genera. Most of them are Rosaceae trees with 11 genera and 17 species. Tree with the most important value is camphor; shrub is Malus halliana, respectively 37.236 and 10.322. Jingting Lake Park(3.611) and Aofeng Park(3.607) have the higher tree species richness index, Fushan plaza(1.276) and Zhaoting square(1.028) lower. The richness index of shrub in Jingting Lake Park(3.348) and Aofeng Park(3.294) are higher, while in Fushan plaza(0.962) and Zhaoting plaza(0.910) are lower. Tree's Simpson index and Shannon-Wiener index are consistent. The highest is Xianshan Park(0.900 and 2.512), the lowest is Zhaoting plaza(0.571 and 0.956). And the other places are similar. Shrub's Simpson index and Shannon-Wiener index are consistent too. The highest is Aofeng Park(0.896 and 2.461), similar to Jingting Lake Park(0.894 and 2.480). The lowest is Zhaoting square(0.568 and 0.937). The highest Pielou evenness index of both trees and shrubs is Aofeng Park, and the lowest is muddy river Parks.
