Abstract: By investigating and analyzing the bio-diversity and distribution patterns of Lagerstroemia indica+Toona ciliate community(Jia), Lagerstroemia indica+ Lagerstroemia indica+Phoebe neurantha community(Yi), Lagerstroemia indica-Ardisia crenata+Lonicera fragrantissima community(Bing) and Lagerstroemia indica-Pilea hookeriana+Cyrtomium macrophyllum community(Ding), we attained the main results as follows: (1)In Jia, Yi, Bing and Ding communities, Patrick richness index(R) followed the order of Ding>Bing>Jia(=Yi)(P<0.05), Simpson bio-diversity index(D) followed the order of Jia(≈Yi)>Ding>Bing(P<0.05), Shannon-Wiener bio-diversity index(H) followed the order of Bing(≈Ding)>Jia(≈Yi)(P<0.05), Pielou evenness index(E) followed the order of Jia(≈Yi)>Bing(≈Ding)(P<0.05); (2)Jia or Yi communities took on evenness distribution pattern, and Bing or Ding communities took on clump distribution pattern. Clump intensity(K), Clump index(I), Mean crowding(m*) and Green index(GI) were followed the order as Bing(≈Ding)>Jia(≈Yi)(P<0.05)。This study will to some degree enrich and broaden the vegetation ecology, and provide theoretical basis for the protecting of wildlife Lagerstroemia indica.
