摘　　要：采用典型抽样法,对重庆市主城区城市森林公园绿地植物的树种组成、不同绿地公园的物种多样性指数以及不同公园绿地木本植物的多样性指数等进行了调查统计及比较分析。结果表明:重庆市公园绿地内植物种类比较丰富,共有44科125属138种;重庆市不同类型公园绿地乔木物种丰富度稍小于灌木的指数值;Simpson多样性指数(D)和Shannon-Wiener(H′)多样性指数表现出相同的趋势,即乔木的多样性指数D和H′均大于灌木的指数值;Pielou均匀度在不同类型的公园绿地之间变化不一,集中在0.3～0.8。大部分灌木均匀度指标值表现出大于乔木的均匀度指标值。Adopted the model sampling law,varieties of trees composition of the predominantly urban city Forest Park Greenland plant in Chongqing,species diversified index and diversified index of different parks green land xylophyta of unique green land parks,etc.had carried on investigation statistics and comparative analysis.The results showed that the research institute was selected the plant kind in the park green land of Chongqing more abundant,125gerus for 44 families in all belongs to 138species.The different kinds of park green land arbor species in Chongqing enrich one degree of index values below the bush slightly;simpson diversified index（D） with Shannon-Wiener（H′）.The diversified index demonstrated the same trend,namely the diversified index D and H′of the arbor was greater than the index value of the bush;the change among different kinds of park green land of Pielou degree of consistency differed,concentrate among 0.3～0.8.The index value of the degree of consistency of most bass demonstrated the index value of the degree of consistency of the greater than arbor.
