The results were as follows:(1) Seeds of 80 species or subspecies could be classified into two groups. Group Ⅰ included the seeds of Gramineae, Cyperaceae, Polygonaceae and Amaranthaceae, and Group Ⅱ included the seeds of Compositae, Euphorbiaceae, Brassicaceae and Umbelliferae.(2) Only FTIRs of the seeds of Brassicaceae were clustered together in the dendrogram,while those of the other families all appeared farraginous.(3) Among FTIRs of the 11 groups of the congeneric species,8 groups were clustered with other genus species, and 6 out of 7 groups of conspecific seeds appeared farraginous in the dendrogram.

At the same time, the biomass of species-rich community was more sensitive to the change of environmental conditions, while communities with fewer species had a little change in biomass.2 There were a total of 87 vascular plant belonging to 27 families and 68 genus in the six communities. Most species had a narrow distribution and a lower local abundance, while few species had a wider range and higher local abundance, and this distribution trends varied in different communities. The endemics were positive correlation to y diversity.
