马鹿花5种配置模式物种多样性比较

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，结果表明院（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。

Species diversity comparation of Pueraria wallichiiDC. in five kinds of configuration mode

Based on the data of five kinds of configuration mode with Pueraria wallichii DC, the species diversity wasanalyzed. 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 pureforest (lu-2) was the lowest; (2) P. wallichii DC-Aleuvites fordii Hemsl forest and P. wallichii DC pure forest (lu-2) were plantedin the same environmental condition, but the richness, Simpson index and Shannon-wiener index of P. wallichii DC-A. fordiiHemsl forest were higher than P. wallichii DC pure forest (lu-2), and this result indicated that the forest of P. wallichii DC plantedwith A. fordii Hemsl was superior to the P. wallichii DC pure forest in the same environmental condition; (3) The variation ofspecies diversity index for different strata were herb layer > tree + shrub layer. This result indicated that herb layer was developedand it had great contribution to the species diversity of P. wallichii DC. in five kinds of configuration mode.
