In order to reveal the landscape application green present situation,the community structure and plant diversity were studied in 3 types 12 residential district spaces area in Kalamay oilfield mining area.By typical sampling methods,the species composition,the species composition,community structure and the species diversity index of plant community were surveied and comparative analysised.The results showed that the total landscape plants belong to 17 families,30 genera and 45 species,and most of them are native spacies.In arbor layer,in terms of the species richness,Shannon-Wiener diversity index,Simpson diversity index and Pielou evenness index,type A>type B>type C.In shrub and ground herb layer,different testing indexes of type A was still hightest,type B and type C were similar.The study proved that the species composition were obsolescence and simple,community structure and type were unreasonable,In order to promote the total ornamental value and ecological benefites about mining residential district green space,it is urgently needed to focus on new species application and increasing the species richness of community in middle and lower layer.
