Floristic analysis of spermatophyte in Jing Bo Hu Geopark

In order to study the floristic characteristics of spermatophyte in Jing Bo Hu Geopark, the Kitagawa standard was used to make floristic analysis of 815 wild spermatophyte spices in this area. The results indicated that, spermatophytes in Jing Bo Hu Geopark have four big floras, including Changbai flora, North China flora, Da Xinganling flora, and Mongolia flora. Changbai flora is the main flora in this area. Besides, there are some common compositions in this four floras, and common compositions take up 73.50％ of the total spermatophyte spices.
