        김윤식(Yun Shik Kim),엄정숙(Jung Sook Um),박선주(Seon Joo Park),장창기(Chang Gee Jang),박찬호(Chan Ho Park) 한국환경생물학회 1998 환경생물 : 환경생물학회지 Vol.16 No.3

        Mt. Ungil (610.2m) is located at 37°33` 38 ∼ 37°35` 38N in latitude and at 127°16` 19 ∼ 127°19`42E in longitude. It also belongs to Choan-Myun, Namyangju-Gun, Kyo^nggi-Do. The vascular plants collected and investigated from July, 1993 to September, 1994 consist of total 360 taxa : 6 forms, 44 varieties, 310 species, 232 genera, 79 families, 39 orders, 5 classes, 3 phyla. The endemic plants of Korea in this area are 10 taxa ; Melandrym seoulense Nakai, Clematis trichotoma Nakai, Lespedeza thunbergii var. intermedia (Nak.) T.Lee., Viola kamibayashii Nakai, Viola seoulensis Nakai, Forsythia koreana Nakai, Scutellaria insignis Nakai, Paulownia coreana Uyeki, Weigela subsessilis L.H. Bailey, Saussurea seoulensis Nakai.

Ungil, the proportion of common distribution with Jeju-Do, Island of Ulreung, the southern and northern part of Korea is 81.67%, 62.87%, 94.44%, 84.72% respectively. Among the useful plants there are 168 taxa of edible plants, 158 taxa of medicinal plants, 50 taxa of industrial plants and 45 taxa of ornamental plants, and 19 taxa of poisonous plants. The individual numbers of endemic, endanger, and rare species tend to decreae in nature. Therefore, it is necessary to strengthen the governmental regularity to limit disturbances by human activities. This action will help the process to maintain the balance in biodiversity resulted from homestasic and to conserve the natural ecosystem.
