Strengthening scientific research and public awareness, which are other two aspects in the management of biodiversity conservation were also discussed.

Protection of bio-diversity-human beings' common responsibility;

Theory discussion on the assessment angle and category of bio-diversity value;

Conservation and Utilization of the Bio-diversity in the Diancangshan Mountain;

Effects of windbreak belt structure in agroforestry on plant biodiversity;

The impact of biological invasion on biodiversity and grassland agroecosystem;

The significance and sustainable utilization plan of biodiversity conservation in West Guangxi Limestone Region;

Plant species diversity of revegetation communities rehabilitated at the beginning of the 1990s and local secondary shrub community on degraded mountainous area of dry-hot valley in Nanjian was studied in 2003.

and clari-fies the latent effects of transgenic plants on species diversity.

The results shows that the species in community are considerably rich,the species abundance of the tree layer,shrub layer and the stratum+shrub layer correspond with Weibull distribution;Compared with other layers,the species diversity index,species richness index and dominant index of the stratum layer are higher,but the evenness is lower.
