| 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-Aleuvites 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. |
