合肥市城市绿化乡土灌木树种的调查研究

An Investigation on Native Shrub Species for Gardening City of Hefei

在对合肥市城市绿化树种系统调查的基础上,统计、分析得出:合肥市城市绿化灌木树种共144种,其中乡土树种47种,占灌木树种总数的32.64%。47种乡土树种,隶属25科、36属,均为被子植物。根据合肥市园林绿化乡土树种应用现状,提出今后合肥城市绿化应坚持以"乡土树种为主,外来树种为辅"的原则,构建乔、灌、藤等复合植物群落,增大城市绿地绿量,对城市生态环境进行科学合理的系统规划布局,为合肥创建国家生态园林城市创造条件。
