Topological indexes of A , B , C and D were all obtained from the different combination of topological vertex degree. A QSAR equation for this series of compounds was established based on the multi-linear regression method and a new group of autocorrelation topological indexes. The results showed that the biological activity is linearly correlated with the volume and branching size of the quinclorac derivatives. Finally, new herbicide was designed based on all QSAR results.

The species diversity of Dipentodon sinicus communities in Yushe National Forest Park of Guizhou province was studied based on the quadrate method. The results showed that Rosaceae, Ericaceae, Betulaceae, Fagaceae, Theaceae, Lauraceae, Caprifoliaceae, Cornaceae were the dominant families in D. sinicus communities of Yushe National Forest Park. In the 10 sample plots, there were 8 which were absolutely dominated with D. sinicus population, the importance value came up to 135.69 on average, and it was far higher than the others. For D. sinicus communities, the abundance index (2.847), Simpson index (0.601), Shannon-Wiener index (1.523), probability of inter-specific encounter (0.601) and species evenness (0.569) of the tree layer were lower than those of the shrub layer (5.580, 0.830, 2.377, 0.829, 0.672, respectively) on the whole. It markedly showed a species diversity characteristic of the mixed broadleaved evergreen and deciduous forest in middle subtropics. In the 10 sample plots, the species diversity level of Q1 was the highest, followed by Q3, Q5 and Q6 was the lowest.
