The floristic aspect of pteridophytes in Guuiujiang region and their relation in contact with Huangshan, Jiubuashan, Qiyunshan, Lushan and Wuyishan, Dinghushan, Qinling regions as well as with the regionalization of chinese flora are discussed. The relation of ecological enveroment and distri bution of pteridophytes in Guniujiang natural reserve is also discussed.
