Abstract:

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，125 gerus for 44 families in all belongs to 138 species.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.
