Characteristics of species distribution in the Baekdoo Great Mountain Chain of Kangwon Province were discussed. Resulting from Detrending Correspondence Analysis based on the floristic composition of 48 mountains, the mountains of the Baekdoo chain tended to aggregate on DCA axis. it represented that there was the peculiar floristic composition of the Baekdoo chain separated from the other mountains. High altitude, longitude near the East Sea and large number of vascular species were main factors for the distribution pattern. And exponential relationships between endemic rare species and number of species were clarified. Even though the regions of the Baekdoo Great Mountain Chain had been conserved relatively well, many regions have been faced to be disturbed for tourism, agriculture, forestry, livestock industry and mining since the local autonomy. Thusm, the necessity for the establishment of large area network through the connection of scattered protected areas in the Baekdoo Great Mountain Chain was suggested. it would play a role as a core of nature conservation to sustain species diversity in Korea.

Extracted genomic DNA from 16 accessions of Codonopsis lanceolata collected from South Korea and the Baekdoo Mt. areas of China were analyzed for their genetic relationships by RAPD. Twenty 10-mer-oligonucleotide primers having reproductive polymorphism were selected for the RAPD analysis. The size of amplified DNA was almost between 125 bp and 2.0 kbp. Sixteen collected Codonopsis lanceolata were analyzed with 20 primers which generated 73(49.3%) polymorphic bands among 148 PCR products. The mean number of polymorphic bands were 7.4 and varied $1{\sim}9$ per primer. It was, thus, demonstrated that RAPD was useful for detecting polymorphism in Codonopsis lanceolata. The range of 1-F value(genetic similarity) was from 0.682 to 0.959. These results indicate variable genetic similarities. By UPGMA (Unweighted Pair Group Method using an Arithmetic average) cluster analysis based on 1-F value, genetic distance among the 16 collected Codonopsis lanceolata was $0.133{\sim}0.400$. It was certainly classified into two groups between collected accessions from Korea and China, and the genetic distance was about 0.281. Both accessions collected from Korea and China showed miner differences, while the genetic relationships of Tonghua Xian and Liuhe Xian from China was farthest with other accessions collected.
