There were lesser and fewer in commercial species and its numbers in the cover net, and the sum of Nemipterus virgatus , Saurida tumbil , Upeneus bensasi , Trachinocephalus myops comprised 95.4% in number and 86.0% in weight of sample catch in the cover net,respectively. The high percentage of juvenile commercial species that were undersized in the codend showed 30.3 mm square mesh codend had more serious damage to most juvenile commercial species, approaching or exceeding 50% in percentage of juvenile species which body length is smaller than fishable size- Trichiurus haumela, Priacanthus tayenus , Navodon tessellatus, Argyrosomus argentatus, Nemipterus bathybius and so on, even exceeding 90% in percentage of juvenile Sepia spp, Loligo spp and Parastromateus niger. In particular, 50% selection lengths ( L 0.5) caught Saurida tumbil and Nemipterus virgatus were smaller than their minimum fishable size.

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.
