摘　　要：以马鹿花5种配置模式的调查资料为基础进行多样性分析,结果表明:(1)5种配置模式中,马鹿花-墨西哥柏林总体丰富度指数、Simpson指数、Shannon-wiener指数以及Pielou指数最高,马鹿花纯林(泸-2)总体丰富度指数、Simpson、Shannon-wiener、Pielou指数最小;(2)马鹿花-三年桐林与马鹿花纯林(泸-2)为同一环境条件下的不同配置模式,马鹿花-三年桐林丰富度、Simpson、Shannon-wiener指数指数均比马鹿花纯林(泸-2)高,说明同一环境条件马鹿花与三年桐混交林比马鹿花纯林物种更丰富、多样性更高;(3)多样性指数在不同群落间的垂直变化幅度均为草本层>乔灌层,说明草本层较发达,对马鹿花5种配置模式物种多样性贡献较大。Based on the data of five kinds of configuration mode with Pueraria wallichii DC, the species diversity was analyzed. The results showed that： （1） The global richness, Simpson index, Shannon-wiener index and Pielou index of the P. wallichii DC-Cupressus lusitanica forest was the highest in these five kinds of configuration mode, while the P. wallichii DC pure forest （lu-2） was the lowest; （2） P. wallichii DC-A leuvites fordii Hemsl forest and P. wallichii DC pure forest （lu-2） were planted in the same environmental condition, but the richness, Simpson index and Shannon-wiener index of P. wallichii DC-A. fordii Hemsl forest were higher than P. wallichii DC pure forest （lu-2）, and this result indicated that the forest of P. wallichii DC planted with A. fordii Hemsl was superior to the P. wallichii DC pure forest in the same environmental condition; （3） The variation of species diversity index for different strata were herb layer 〉 tree ＋ shrub layer. This result indicated that herb layer was developed and it had great contribution to the species diversity of P. wallichii DC. in five kinds of configuration mode.
