Abstract
Mt. Cheongok, Mt. Doota and Mt. Joongbong located at $37^{\circ}25^{\prime}26^{{\prime}{\prime}}{\sim}37^{\circ}27^{\prime}20^{{\prime}{\prime}}N$ in latitude, at $128^{\circ}55^{\prime}20^{{\prime}{\prime}}{\sim}129^{\circ}01^{\prime}58^{{\prime}{\prime}}E$ in longitude. The results of vascular plants - collecting and their investigation from June, 1995 to Octorber, 1997 are as follow ; The vaular plants collected and investigated in this area consist of 103 families, 324 genera, 516 species, 2 subspecies, 81 varieties, 10 formae, total 610 taxa in Mt. Cheongok, 104 families, 338 genera, 568 species, 2 subspecies, 84 varieties, 9 formae, 1 hybrid, total 664 taxa in Mt. Doota, 99 families, 303 genera, 453 species, 1 subspecies, 73 varieties, 10 formae, 1 hybrid, total 538 taxa in Mt. Joongbong. The Korean endemic plants were 22 taxa, 25 taxa and 17 taxa in each surveyed area. Rare or endangered plants were 19 taxa, 20 taxa and 11 taxa in each surveyed area. Also, naturalized plants were 17 taxa, 16 taxa and 14 taxa in each surveyed area.
청옥산, 두타산, 중봉산(북위 $37^{\circ}25^{\prime}26^{{\prime}{\prime}}{\sim}37^{\circ}27^{\prime}20^{{\prime}{\prime}}$, 동경 $128^{\circ}55^{\prime}20^{{\prime}{\prime}}{\sim}129^{\circ}01^{\prime}58^{{\prime}{\prime}}$)을 대상으로 식물상(植物相)을 조사한 결과, 조사지역내의 관속식물(管束植物)은 청옥산 103과(科) 324속(屬) 516종(種), 2아종(亞種) 81변종(變種) 10품종(品種) 1잡종(雜種)으로 총 610종류(種類), 두타산 104과(科) 338속(屬) 568종(種) 2아종(亞種) 84변종(變種) 9품종(品種) 1잡종(雜種)으로 총 664종류(種類), 중봉산 99과(科) 303속(屬) 453종(種) 1아종(亞種) 73변종(變種) 10품종(品種) 1잡종(雜種)으로 총 538종류(種類)가 분포하였다. 그리고 소산식물(所産植物) 중 한국특산식물(韓國特産植物)은 청옥산 22종류, 두타산 25종류, 중봉산 17종류가 분포하였으며, 희귀(稀貴) 및 멸종위기식물(滅種危機植物)은 청옥산 19종류, 두타산 20종류, 중봉산 11종류가 분포하는 것으로 나타났고, 조사지역내의 귀화식물(歸化植物)은 청옥산 17종류, 두타산 16종류, 중봉산 14종류가 출현하였다.
