In June and July of 2003, a field survey on the vegetation of 22 Chinese alligator habitats distributed in Nanling county, Jingxian county, Guangde county, Langxi county and Xuancheng city of Anhui province was conducted, and the plant species of the habitats were recorded and analyzed. The results showed that the vegetation of the whole habitats was secondary, and there were 294 species vascular plants, belonging to 92 families. Pteioblastus amarus shrubbery could be found in all sites, and part differences of the vegetation consisted in different habitats. The relationship between Chinese alligator and habitat vegetation was also analyzed. All of these could offer some basic botanical data for the further protection of the Chinese alligator.
