根据资料收集和实地调查的数据,对安国市各类绿地绿化植物群落结构与多样性进行分析。结果表明:绿地中重要值大于10%的乔灌木有16种,均为当地适生树种。道路绿地中植物群落多为乔木、或乔灌结构;附属绿地中多为乔灌草、灌草复合结构;公园绿地中乔灌草复合结构。各类绿地中,乔木均匀度指数最高,灌木次之,草本最小;灌木层的多样性指数最高,乔木层次之,草本层最低。
根據資料收集和實地調查的數據,對安國市各類綠地綠化植物群落結構與多樣性進行分析。結果錶明:綠地中重要值大于10%的喬灌木有16種,均為噹地適生樹種。道路綠地中植物群落多為喬木、或喬灌結構;附屬綠地中多為喬灌草、灌草複閤結構;公園綠地中喬灌草複閤結構。各類綠地中,喬木均勻度指數最高,灌木次之,草本最小;灌木層的多樣性指數最高,喬木層次之,草本層最低。

Different vegetation of green space in Anguo City was discussed ,in its plant com-munity and diversity by analyzing the data from field survey .The results showed that there are 16 kinds of trees and shrubs with more than 10% important value in its green specie , which are all well growing local species .The majority of greening plants are arbors ,or ar-bors and shrubs in the road green space .The plant community of subsidiary green space is mostly composited of herbages ,shrubs and arbors or herbages and shrubs .The city park green space is coverd mostly with plant community of herbages ,shrubs and arbors . The Pielou indexes of arbors is the highest and that of herbages is the least .T he highest diversity indexe is from shrubs with the least from herbage .
